Here at Queensac, we adore queen sacrifices. Almost as exciting is the double-rook sac! Yassar Seirawan and Nikolay Minev have produced a compelling book, Take my Rooks!, devoted to this theme. They have found more than 130 games that involve the theme and help us to understand when it works, when it doesn't, and what some players missed along the way.

Here are all of the games in the book and here are two examples. The first is a quick look at the nature of the double rook sacrifice; the second is a battle between two titans that ends quite quickly.

In 1965, Vladimir Vukovic authored perhaps the premier manual on tactics, The Art of Attack in Chess. More than just a presentation on how to attack a castled king, he classifies attacks and focuses upon grandmaster games to illustrate his points. He provides a special section on the games of Capablanca and Alekhine, a real treat for those who have not yet seen these games.

The book is available in a new edition, which fortunately makes it available to the next generation of chess players. Here are all of the games and positions in the book and here is just one example, a nice attack conducted by Yugoslavian GM S. Gligoric.

Five time Russian champion Rashid Nezhmetdinov sustained his standing atop the world of chess by attacking... always attacking. As the story goes, he defeated Mikhail Tal so many times that Tal hired him as his trainer.

In 2000, Thinkers' Press published Russian Correspondence master Alex Piskin's Super Nezh: Chess Assassin, a collection of 100 well annotated games from this Russian champion previously little known in the west. The book is full of surprises (Nezh invented the poisoned pawn variation of the Najdorf!) and many ferocious attacks. Unfortunately, the book is now out of print, but it shows up used at an affordable price from time-to-time.

Here are all of the games in the book and here is, perhaps, Super Nezh's most famous win.

Chess lessons occupy my weekend mornings. For years, I've shared my own games and ideas and, of course, reviewed my students' games. During the past year, I've introduced something fun into the agenda. Thanks to the Internet Chess Club, my students and I watch live Grandmaster games and to predict their moves and plans. I know that many players join the ICC to play. The great benefit, in my view, is the ability to watch these games as they are played.

Today, we were following some of the games live from the Russian Chess league. Apart from wtching some interesting chess, it's also quite instructive to observe how the strongest players allocate their time. While many of us finish our games early, they are aware that even the smallest early inaccuracies can cost the full point. So it's quite common to see just 20 or so moves fill most of the time control.

Today's game was no exception, but I call your attention to the diagram. That position dwelled on our screen for about 30 minutes. I wish that I could tell you that my students and I figured out all the complications. The fact is, I wound up devoting a few afternoon hours to the task and, indeed, there were a more than a few surprises that we had missed.

I recommend that you set up a diagram position on the board, turn off the TV, and write down your analysis. You may find, as my students have, that the exercise builds chess muscles!

The most exciting defense for black? Thanks to adherants like Bobby Fischer and Lev Polugaevsky, the Sicilian Najdorf might get the most votes. It certainly remains at the cutting edge of opening theory.

There are many books on the Najdorf. Today, I focus on one, a 1993 effort by Danny King Winning with the Najdorf. He reviews all of the mian lines in 61 well annotated games played between the early 1940s and the mid 1990s.

He includes a few of his own games, but the majority are highly instructive examples such as the following

Ader - Fischer [B99]
Santiago Santiago, 1959

1.e4 c5 The Sicilian Defense 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 Nf6 attacks the e-pawn 5.Nc3 Defending the pawn. The sequence prohibits c2-c4 and the Maroczy bind (pawns on c4 and e4). 5...a6 The Najdorf variation. 6.Bg5 Fischer tried many different moves here, but used mostly Bc4 and Bg5 6...e6 idea Be7 7.f4 idea Qf3 7...Be7 8.Qf3 Qc7 9.0-0-0 All standard stuff 9...Nbd7 10.f5 More common is g2-g4, Bxf6 and g5 10...e5 A normal reaction. Black creates a hole on d5, but the f5-pawn now blocks the normal Nf5 11.Nb3 b5 idea b4 and Bb7 with pressure upon the fixed e4-pawn. 12.a3 To prevent b4, but a3 weakens the queenside. 12...Bb7 Two attacks upon e4 13.h4 Rc8 Delaying ...0-0, which would give white a target for the attack. Black is preparing the ...d5 break and stops Nd5 (Qxc2#) 14.Bd3 Over-protecting both c2 and e4 14...h5! A lovely move, stopping g2-g4 and, in fact, stealing the g4 square for the Nf6 15.Kb1 Nb6 Idea Nc4xb2 and Qxc3 16.Nd2 Trying to stop Nc4 16...Ng4 Trading the bad Be7 for white's good Bg5 17.Bxe7 Qxe7 idea Rxc3! 18.Nf1 Diagram

As a correspondence chess player, I'm accustomed to writing out pages and pages of analysis before I mail a move. German GM Robert Huebner rose quickly through the ranks in the 1970s through steadfast devotion to thorough analysis over-the-board. When ChessBase was in version 4.0, there was a limit to the amount of analysis that one could place inside a game. They set it quite high, expecting that no normal players would hit it. I did regularly, requiring that I split my games into parts. So too with Huebner, whose detailed analysis is legend.

In 1996, Huebner authored a memorable book, 25 Annotated Games. That may sound like a thin book, but those 25 games occupy 413 dense pages (with more diagrams within the analysis than within the game scores)! The analysis is detailed and comprehensive, a real joy to those who demand proof or just enjoy chess as science.

Here are all of the games in the book and here are my rather paltry annotations of one of the games. I hope that you get some sense of what in store to those who own this treasure.

Huebner,R - Visier Segovia,F [B89]
Spain, 1974

1.e4 c5 The Sicilian Defense 2.Nf3 e6 3.Nc3 A frequent move, measuring black's intentions. White is unlikely to play a Closed varaition with the Nf3 blocking f2-f4 3...Nc6 4.d4 cxd4 5.Nxd4 Back to a main line... Black can choose among ...a6, ...Qc7, and ...d6 5...d6 6.Be3 Nf6 7.Bc4 Transposing to the Sozin Sicilian. The more usual move order is: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Bc4 e6 7.Be3 7...Be7 8.Qe2 The Velimirovic attack 8...a6 9.0-0-0 Qc7 10.Bb3 All known and book 10...0-0 And an interesting choice now for white. If 11.g4, black plays Nxd4 when the natural Bxd4 fails to e6-e5. So white would have to play 11.g4 Nxd4 12.Rxd4 e5 13.Rc4. Better to prepare g4 with... 11.Rhg1 Na5 12.g4 b5 13.g5 Nxb3+ 14.axb3 Nd7 Again, all well known to theory. Huebner offers just a half page to the first 14 moves, and 26 pages to last 13 moves! 15.Rg3 There's much to learn from Huebner's method. First, analyze the key candidate moves 15.Nf5 and 15.f4... not necessarily to play them, but to find out why they may not yet work. And then play the moves that help to set them up. 15...Bb7 16.f4 [16.Qh5 Rfe8 17.Rh3 Nf8] 16...b4 Diagram

Most books on chess openings have a bias towards one side or another. The bias is natural because players tend to play the opening as white or black but rarely both.

An exception is The Caro Kann in Black and White by Anatoly Karpov and Alexander Beliavsky. Beliavsky authored the first half of the book, looking at the opening from the white perspective. Karpov takes on the black view in the the second half. Again, a game perspective, and a refreshing balance.

Of course, there's much to wonder about here. I get the impression, hard to prove, that both players have held back on the best strategies to defeat their pet lines, but the games are well annotated and worth your attention.

Here are all of the games in the book and here are my annotations to the last game, a nice theoretical novelty that Karpov had prepared for Kasparov but unleashed instead on Kamsky.

Kamsky - Karpov [B17]
Dortmund, 1993

1.e4 c6 The Caro-Kann Defense 2.d4 d5 Counter-attacking as in the French, but here, avoiding a bad Bc8 by not having played e6 3.Nd2 Avoiding Nc3 when black has the additional option of playing g6 and Bg7. The fianchetto does not work well here because white can respond with c2-c3 3...dxe4 4.Nxe4 Nd7 A solid variation, preparing rather than playing Ngf6 5.Ng5 Sharp, third move for the knight but an ideal post. ...h6 Ne6! 5...Ngf6 [5...h6 6.Ne6 fxe6 7.Qh5+ g6 8.Qxg6#] 6.Bd3 idea Qe2 and 0-0 6...e6 7.N1f3 Guarding the d4-pawn and eyeing e5 7...Bd6 8.Qe2 h6 9.Ne4 Nxe4 10.Qxe4 Nf6 11.Qh4 Diagram

Just how bad are bad bishops? And are all bad bishops equally bad? These are some of the questions explored in a 1989 Thinkers' Press book Strategical Themes by Senior Master Tom Unger.

I adore books that focus on themes, and this book has several: Bad Bishops, Double Fianchettos, central pawn rollers, and centralization. The book provides a good discussion on each theme and, as important, useful examples to drive the points home.

I offer all of the games in the book as well as an instructive example from the section on bad bishops. As you'll see, some bad bishops are worse than others.

Here's the position from which Unger starts. The first question is which bishop is worse, the white Bf3 or the black Be717.Qe1 The answer lies in the pawn structure.

You don't become world champion without mastering the endgame. That's probably fair to say, and Botvinnik's On the End Game gives a pretty fair view of what it takes. Certainly experience, but also a fair imagination and a strong dose of creativity.

The book contains 25 of Botvinnik's endgames against some of the strongest players of the day, Alekhine, Keres, Bronstein, Fischer, Larsen, Portisch, Najdorf, Taimanov, and many others. The plans and more orders are crisp, well annotated, and worth your time.

Here are all 25 games in the book. Where I could find them, I included the full game score rather than just the endgame so that you'll have a chance to see the transition to these interesting endgames.

Finally, here is the game of the day, one of the endgames in the book. There are undoubtedly several winning ideas here, but I think that you will find it interesting to see how Botvinnik planned out the win. Before you play it through, take five minutes to see what ideas you can assemble.

When I write stories, I like to have to have a good sense of how the story will finish. If I know the ending, I can more easily get there. So too in chess, expertise in the endgame is a great aid throughout the middlegame. If I trade off my pieces, is the endgame favorable? It's a key question that underlies much good chess.

I like Peter Griffith's book Exploring the Endgame in no small part because he often provides complete games. It's not simply a question of showing off some exemplary endgame technique. These folks knew what to do in these endgames. It's interesting to see how they got there.

Here are the 54 games in the book. Griffiths divides them into pawn, knight, bishop, rook, and minor piece endgames. Here's one example from the King and pawn section with my own annotations.

Shamkovich - Watken
USA USA, 1976

Diagram

1...Kf8 Black must begin by moving within the square of the pawn. Just imagine a square, in this case reaching from b4-b8-f8-f5. To prevent the b-pawn from queening, the black king must be able to stay within the shrinking square as the b-pawn advances. 2.Ke3 White knows that the king needes to move ahead of the passed pawn to clear its advance 2...Ke8 3.Kd3 Heading towards b5 3...Kd7 4.Kc4 Kc7 5.Kb5 Kb7 Diagram

Black takes the opposition, blocking the further advance of the king.6.f4 White will win quickly if the black pawns run out of safe moves. The king would then move to a5 and assist the advance of the b-pawn. So more accurate may be g5 immediately limiting the movement of the black f- and h-pawns. [6.g5 e6 7.f4] 6...e6 7.g5 It sure works here! 7...Kc7 exd5 and e5 fail, but so does giving ground to the king 8.Ka6 exd5 9.Kb5 Kb7 10.Ka4 The point is simple. White will capture the d-pawns and wind up near black's kingside. 10...d4 11.Kb3 d5 12.Kc2 Kc6 13.Kd3 Kb5 14.Kxd4 Kxb4 15.Kxd5 Kb3 16.Ke5 With an easy win by capturing on f7. 1-0

There are many game collections, and playing through them will improve your chess. In 1952, R.N.Coles wrote Epic Battles of the Chessboard, an unusual collection because most of the games feature astounding recoveries. To be sure, there are exciting contests and often astounding combintations, but these games were selected because they are tenacious, resourceful, and more closely resemble the type of chess that one might aspire to play at the club.

Here are all of the games in the book and here is one of them with my own annotations. It's a game played between two Swedish masters during World War 2. I think that you will enjoy it.

When Mikhail Botvinnik defeated Capablanca in a 1925 simultaneous match, the Cuban world champion predicted great things for the young 14-year-old. And so it was to be for the great Botvinnik, a cool pragmatist who precisely dismanted the competition for four decades.

His 1982 book, 15 Games and their stories takes us from that 1925 match through 40 years of great chess punctuated by the stories behind the matches.

Here are all 15 games in the book as well as my notes to one of his efforts from 1934, a nice example of the calculating care that propelled Botvinnik to the World Championship.

What's the most important discovery of the 1490s? Columbus's discovery of American in 1492? Nah! It was Lucena's discovery in 1497 of how to win Rook and pawn endgames! After all, the Vikings had already discovered the Americas, and without Lucena, there'd have been no hope for chess.

I feature today Edmar Mednis's famous book, Practical Rook Endings. It's a small, 70 page booklet, but it's chock full of what you need to compete in a rook and pawn endgame. Many games between equally matched players end in the endgame, and rook and pawn endgames are by far the most common. We all have learned to make sure that we keep our rooks active on open files and to place our rooks behind advanced passed pawns. But there are subtleties, and the key is recognizing early on when to exchange down to an advantageous rook endgame and, of course, what to do once you get there.

Here are all of the games and positions in Mednis's book and, in honor of the 500th anniversary of Lucena's historic discovery (which surely deserved more recognition than it got), I offer an example of his contribution. Note that white has correctly placed his king on the queening square (and kept the white king from getting to the queening square to prevent the queening of the pawn), but how to advance the pawn? It appears that the white king simply cannot move out of the way without being subject to perpetual checks from the Black rook.

Lucena
1497

Diagram

It's white to move and win, but I doubt that anyone would discover it over-the-board without some knowledge of Lucena. 1.Rg2+ First, move the black king away and give the white king a chance to move out. 1...Kh7 Approaching the rook as quickly as possible 2.Rg4 Here's the key move. White sees ahead to move 7, the first steps of "building a bridge" 2...Kh6 Trying to reach the rook 3.Kf7 The threat, of course, is e8(Q) 3...Rf1+ Getting behind the pawn and capturing it is not an option. White can mate with a king+rook vs king. Can black check the king perpetually? 4.Ke6 Re1+ Continuing the attack on the king or the pawn will queen 5.Kf6 Not Kf5? or Kd5? when black draws with Rxe7. The additional threat is Rh4# 5...Rf1+ 6.Ke5! Everything is coming together. Again, the threat is e8(Q) 6...Re1+ 7.Re4 And white queen's. Not bad for 1497! 1-0

Volume two of Polugaevsky's Sicilian Labyrinth looks at pawn structures, key central squares, open files, piece placement, and strategic sacrifices. He also covers typical endgame features in the Sicilian, notable the importance of the open c-file for black and using the two bishops when you are fortunate enough to have them.

The discussions in the book provide excellent proof of the importance of playing through master games, especially when they are well annotated. Here are all of the games in volume two, and here is an example from the book with my annotations. Note the importance of the e5 square for black and the use of the semi-open c-file.

Tarnowski,A - Boleslavsky,I [B82]

Lev Polugaevsky played the Sicilian throughout his GM career and introduced many new, sharp vaiations, including a key Najdorf line now named after him.

In 1991, he introduced a wonderful two volume set, The Sicilian Labyrinth, that draws upon his many years of experience and insight. Volume 1 focuses upon avoiding opening disasters, preparing theoretical surprises for your opponents, and a variety of counter-attacking measures for black.

Here are all of the games in Volume 1, and here are my annotations to one of the games presented. The game is the 24th in the 1985 Kasparov-Karpov match and represents the culmination of their Sicilian discussion in the match. And yes, it's yet another Hedgehog!

Karpov,A - Kasparov,G [B85]
Moscow (24), 1985

1.e4 c5 The Sicilian. Black's idea is to inhibit d2-d4 and to open the c-file for his major pieces 2.Nf3 d6 Very flexible, with the possibility of a Najdorf (...a6), Dragon (...g6), or Scheveningen (...e6) 3.d4 cxd4 Capturing towards the center, opening the c-file. 4.Nxd4 Nf6 Attacking the e-pawn in order to stop c2-c4. 5.Nc3 The main line, but now white cannot establish the "Maroczy bind" with pawns on c4 and e4 (stopping counterplay with d7-d5) 5...a6 The Najdorf variation. In many lines, Black can now play ...e5 without having to face Nb5 or Bb5 6.Be2 A solid continuation. More challenging, perhaps, are Bg5, Bc4, and the English Attack with Be3 or f3 6...e6 A Kasparov favorite, establishing a solid pawn center, lessening the possibility of e4-e5 7.0-0 Be7 8.f4 0-0 9.Kh1 Removing the king from the diagonal. 9...Qc7 A natural post for the queen in these lines. The a- and e-pawns prevent knight attacks on b5 and d5. 10.a4 To prevent ...b5 10...Nc6 Hedgehog players often prefer to develop the queen knight on d7, but here, white can quickly play g4-g5. The Nf6 needs d7 for its escape. 11.Be3 Re8 Typical play, with the idea of Bf8 and a late kingside fianchetto 12.Bf3 Rb8 and removing the rook from the long diagonal 13.Qd2 Bd7 Aiming towards c6 and maintaining contact with the e6-pawn 14.Nb3 Threatening a4-a5. Black would then have a structurally weak b-pawn. 14...b6 Completing the Hedgehog structure. Black's development remains sub-optimal... The Nc6 and Bd7 are misplaced, but the structure offers black plenty of time to reorganize. 15.g4 Idea g5... Black must vacate d7 15...Bc8 16.g5 Nd7 17.Qf2 Bf8 With no pressure on d6, black pursues the idea of Rg6 and Bg7 18.Bg2 Readying f4-f5 18...Bb7 19.Rad1 g6 20.Bc1 Rbc8 [20...Nc5 After the game, Kasparov preferred Nc5] 21.Rd3 Idea Rh3, Qh4 21...Nb4 22.Rh3 Bg7 Diagram

After the game, Karpov believed that he missed a win here with f5. Kasparov felt that he could have held.23.Be3 [23.Qh4 Nf8] 23...Re7 24.Kg1 Rce8 25.Rd1 f5 And just like that, black's position comes alive. 26.gxf6 Nxf6 threat Ng4 27.Rg3 [27.Bxb6 Ng4 28.Bxc7 Nxf2 29.Kxf2 (29.Bxd6 Nxd1 30.Bxe7 Nxc2 31.Nxd1 Rxe7~~ 32.e5) 29...Rxc7 30.Rxd6 Nxc2+/=] 27...Rf7 28.Bxb6 Qb8 29.Be3 Nh5 30.Rg4 Nf6 31.Rh4 g5! 32.fxg5 Ng4 [32...Nxe4] 33.Qd2 [33.Qxf7+ Kxf7 34.Rxg4 Nxc2 35.Bf2 Ba8-/+] 33...Nxe3 The absense of the dark-squared bishop will be felt.

A long Township Committee meeting tonight (so a shorter BLOG). Yes, I ran for office 5 years ago... and got elected! To make matters worse, I ran for re-election and won again! So I have civic obligations on many nights of the week, but I still find time for my real passion ... because chess is fun!

Some thoughts about new directions for the web site. Please feel free to comment on these possibilities and to offer your own suggestions on the Message Board here. During the coming year, I'm going to try to add a tactics page that will randomly offer a different position every time you load it... It will take some time to load in 3000-4000 positions, so I ask for some patience!

I built Chess is Fun to provide free instruction, and the site has obviously grown and grown over the past 12 years. Time now to consider a special "for-pay" component. Everything here (including the BLOG) will remain free. So what will be offered?

A huge archive of openings, great games, and about 200 online books. I may also offer my Hedgehog book in a special teaching area... I haven't succeeded in interesting any publishers in the book, essentially the Hedgehog for Kids, but perhaps there will be some online interest. I hope to be ready by the fall. I'll update you as I approach completion.

And of course, there's the interactive lesson facility. A few more tests will be needed to make sure that it's up to higher demand, but I suspect that there must be folks out there who'd enjoy being able to interact in such an instructional setting.

That's it for today. During the next two days in the BLOG, I hope to cover Polugaevsky's two volume Sicilian Labyrinth. Some great games, and excellent analysis. But I need more time to enter all the games! Good chess, all.

Correspondence chess has a reputation for long, careful, positional games with detailed, accurate analysis. All the more reason that a book of correspondence chess miniatures might be hard to assemble.

Tim Harding, the editor of Chess Mail, the wonderful publication and web site, took on this task with Startling Correspondence Chess Miniatures. Here is a collection of 100 entertaining, often theoretically important short games all played via e-mail or through the post. The games are enjoyable and also contain traps into which your next opponents just might fall.

Here are all of the games in the book and here is one of mine that I hope will be included in volume two... yes, my way of sneaking one of my correspondence chess miniatures into the BLOG!

In 1991, Mihai Suba authored Dynamic Chess Strategy, an exciting collection of 36 of his games. Notable is his willingness to break free of conventional chess wisdom and seek new, flexible structures. I first took note of the book because Suba had embraced the Hedgehog and had even used it to achieve his GM title.

Here were games and annotations that attempted to reconcile classical chess with new ways of thinking about the game. I have enjoyed this book. To make it easier to read, I offer all of the games in the book and one example with my own annotations, one of Suba's hedgehogs.

Vukic,M - Suba,M [A30]
Vinkovci, 1977

1.Nf3 A perfectly reasonable opening move, often with the idea of a kingside fianchetto, d3, and a delayed e4 1...Nf6 Awaiting events. ...d5 and ...c5 are perfectly reasonable alternatives 2.g3 Here's the fianchetto, with the idea of placing the Bf1 on the long diagonal 2...b6 Required now if you want to play a Hedgehog 3.Bg2 Bb7 Another forced move pair. 4.0-0 e6 or ...c5 in order to make sure that white's d4 meets the pawn exchange. 5.c4 c5 6.d4 cxd4 again, required, to bring a piece to d4. Now Nbd7 will have access to both c5 and e5 7.Qxd4 Avoiding the exchange of bishops after Nxd4 7...d6 Not the natural Nc6 because the knight there would block the Bb7 and the action later down the c-file. 8.Nc3 a6 Completing the Hedgehog pawn structure. The pawns on e6 and a6 prevent the white knights from harrassing the black queen when it posts on c7 9.Rd1 Qc7 The usual move, with the idea of Nbd7, Be7, Rc8, and 0-0 10.b3 Defending the c-pawn against the coming threat of Rc8 10...Nbd7 The normal Hedgehog square. The Qd4 is poorly posted and will likelt repost without black having to play Nc6 11.Bb2 Be7 12.e4 A position that could be reached from many different openings, including the Sicilian and Queen's Indian. 12...0-0 13.Qe3 Rfe8 Typical placement, anticipating Bf8 and a ...d5 pawn break. 14.Nd4 Bf8 15.Rac1 Rad8 Or Rac8 16.h3 g6 Typical in the Hedgehog, a late kingside fianchetto once the d6-pawn is secure 17.Kh2 Bg7 18.Qe2 Qb8 Also typical, often with the idea of Qa8 putting more pressure on the white e4-pawn 19.Qc2 Rc8 20.Qd2 Nc5 Three attacks on e4 21.Re1 Three defenses 21...Qa8 Four attacks. Most players would crumble under such pressure. 22.f3 The new structure weakens the g3-pawn and locks in the Bg2 22...Qb8 TRansferring back to pressure g3 23.Rcd1 Ba8 Again typical, idea b6-b5 24.Nde2 Two attacks on d6 24...Red8 25.Nd4 White would be content with the a draw. 25...Ncd7 Suba has used the Nc5 to gain the f2-f3 concession... He now transfers the Nc5-d7-e5 26.Qf2 Ne5 27.Qe2 Avoiding f3-f4, again weakening e4 27...Nc6 28.Nc2 Nh5 Looks bad, but the simple powerful threat is ...d6-d5 and Qxg3 29.f4 Preventing ...d5, but now black has 29...b5 The typical pawn break in the Hedgehog 30.cxb5 axb5 31.Bf3 [31.Qxb5 Bxc3 32.Qxb8 Nxb8; 31.Nxb5 Bxb2] 31...Ne7 idea Bxc3 32.Nd4 b4 33.Na4 Nf6 34.e5 Usually unplayable in the Hedgehog 34...dxe5 35.fxe5 Bxf3 36.Nxf3 Nfd5 Diagram

And Black emerges with a powerful position, notably an unassailable central Nd5 and the better dark-squared bishop37.Rc1 Bh6 38.Rc4 Ne3 Knight to the 6th! 39.Rcc1 N7d5 40.Rxc8 Rxc8 threat Rc2 41.Qf2 Nf5 42.Re2 Be3 43.Qe1 Qb5 44.Nd2 Qd3 another nice entry square. 45.Nf1 Rc2-+ 46.Rg2 Rxg2+ 47.Kxg2 Qe4+ 0-1

Chess draws have the reputation for being dull and boring, the end-product of over-preparation or simply agreements between GMs in order to get early to the tennis court. Wolfgang Heidenfeld knew better. He had just completed a manuscript featuring the most exciting draws ever played when he died in 1981. We are fortunate that the manuscript was published the next year.

Here are all 70 of the games in the book. Taken from tournaments over a 100 year period, you are likely to find more excitement in this collection than in many modern touranments.

Of all of the games in the book, Heidenfeld felt that the following game was probably the best draw ever played. You be the judge. The game is especially noteworthy because it involve a truly great player in a correspondence game.

A new book just out Bobby Fischer Goes to War: How the Soviets Lost the Most Extraordinary Chess Match of All Time recounts the historic events surrounding the famous 1972 match. The book has been met with acclaim, in part, according to reviewers, because it does not interrupt the narrative with the occasional game. I have not read the book and you are welcome to join the masses in harkening back to that amazing event in chess history.

I thought, however, that I might focus instead on a true classic about Bobby Fischer, the 1965 account by Frank Brady: Profile of a Prodigy: The Life and Games of Bobby Fischer. Brady's book predated Fischer's classic My 60 Memorable Games by four years. The first 100 pages are an excellent, highly readable narrative about Fischer's life and accomplishments. The second half focuses briefly on 75 Fischer games, including many that subsequently appeared with more extensive notes in Fischer's book.

I present all of the games in Brady's Profile of a Prodigy. I also add my notes to one of the games that appears in both Brady's and Fischer's book. It's a game from 1963 in which Fischer dusts off an idea of Steinitz's. The move flies in the face of the old adage: "If it looks bad, it is bad." 9.Nh3 does not look appealing and yet, Fischer defeated Bisguier and the move became quite popular as this short collection of additional games demonstrates.

Fischer,R - Bisguier,A [C59]
New York State Open Poughkeepsie (5), 01.09.1963

1.e4 Fischer's favorite move, it places a stake and the center, threatens d4, and opens the lines for the Qd1 and the Bf1. 1...e5 Solid, stopping d4 2.Nf3 Attacking the e5-pawn 2...Nc6 Defending the pawn 3.Bc4 Less ambitious than the Ruy Lopez, Bb5, but a favorite of young players and in chess's romantic era. 3...Nf6 The Two Knight's Defense, a solid choice in the hands of a master 4.Ng5 Often criticized today. After all, the knight, just developed, has moved again, and white's whole queenside remains "in the box." But how to defend the f7-pawn? 4...d5 The usual response, blockling the Bc4's attack on f7. The Wilkes Barre Variation with 4...Bc5 is double edged but playable. 5.exd5 Taking with "the little thing." There's no reason to cede the valuable Bc4xd5? 5...Na5 A key response, avoiding 5...Nxd5 when white has the wonderful choice between 6.d4! and the Fried Liver Attack with 6.Nxf7!? 6.Bb5+ Better than Morphy's occasional 7.d3. 6...c6 7.dxc6 bxc6 All standard and book. Black is down a pawn but has far superiod development. White could try the sharp Qf3 here, but that attack is artificial. Better simply to retreat and develop as quickly the queenside as possible. 8.Be2 h6 Diagram

All book, expecting 9.Nf3 e4 10.Ne5 Bd6 when white will play 11.d4 or 11.f49.Nh3!? Resuscitating a line used successfully by Steinitz in his 1892 world championship match and henceforth forgotten! 9...Bc5 10.0-0 Fischer later improved with d3 (see the following game) with the idea of holding back on 0-0 in case Black captures on h3. The point is that the obvious Bxh3 capture opens the g-file for operations against the Black king [10.d3 0-0 11.Nc3 Re8 12.0-0 Bxh3 13.gxh3 Qd7 14.Bg4 Nxg4 15.hxg4 1-0 Fischer,R-Radojcic,M/Poughskeepie 1963/Fischer (15)] 10...0-0 11.d3 Aiming for f4 11...Bxh3 In the 1992 game, Chigorin never took the knight, preferring instead to leave it there, out of play. [11...Nd5 12.c4 Ne7 13.Kh1 Bxh3 14.gxh3 Nf5 15.f4 exf4 16.Bxf4 Ne3 17.Bxe3 Bxe3 18.Nc3 Rb8 19.Rb1 Qd7 20.b4 Nb7 21.b5 Nd8 22.Bg4 Qd4 23.Rb3 cxb5 24.Nxb5 Qc5 25.Rf5 Qe7 26.Nc3 Rxb3 27.axb3 Bd4 28.Nd5 Qd6 29.b4 g6 30.Rf1 Nc6 31.Qd2 Kg7 32.Bf3 Rd8 33.Bg2 Be5 34.Qe3 Rd7 35.Re1 f6 36.b5 Nd4 37.Qf2 Qb8 38.Be4 Ne6 39.Rf1 Rf7 40.Bxg6 Kxg6 41.Qf5+ Kg7 42.Qxe6 Qb7 43.d4 Bb8 44.Rg1+ Kf8 45.Qf5 Bd6 46.c5 Be7 47.c6 1-0 Steinitz,W-Chigorin,M/Havana 1892/MainBase (47)] 12.gxh3 White remains up a pawn, but the extra pawn is on h3. But the absense of Black's light squared bishop takes the stuffing out of Black's counter-play. 12...Qd7 Attacking the weak h3 pawn 13.Bf3 Avoiding 14.Bg4 Nxg4 when Black gets good attacking chances with ...f5 13...Qxh3 14.Nd2! [14.Bg2 and Fischer gives 14...Qh4 15.Qe1 Rfe8 16.Qxa5 Ng4 17.h3 Bxf2+ 18.Rxf2 (18.Kh1 Qg3-+) 18...Qxf2+ 19.Kh1 e4] 14...Rad8 15.Bg2 Now on Qh4 Nf3! 15...Qf5 16.Qe1 eyeing the e4-square as well as the unprotected Na5. Fischer also needs to over-protect the f2-pawn in order to play Kh1 (off the diagonal) and f4 16...Rfe8 17.Ne4 White's pawn structure is far superior to Black's, so exchanges should lead to a favorable endgame. Note the weak black pawns on a7 and c6 17...Bb6 18.Nxf6+ Qxf6 19.Kh1 Preparing f4 19...c5 Inhibiting d4, but blocking the Bb6. Fischer felt that g5 was needed to prevent f2-f4 20.Qc3 Stops c5-c4 and strengthens f4. 20...Nc6 [20...g5 21.f4! gxf4 22.Bxf4] 21.f4 Nd4 Knight in the the middle of the board, but it can be attacked by a pawn. 22.Qc4 Preparing c3 22...Qg6 23.c3 Nf5 24.fxe5 Activating the bishops 24...Rxe5 25.Bf4 Re2 26.Be4 Diagram

26...Rxb2? A significant error at a key moment. Fischer gives the following variation. [26...Re8 27.Bf3 (27.Rg1 Qh5 28.Raf1 Ne3 29.Qb5 Rxe4 30.dxe4 Nxf1 31.Qe8+ Kh7 32.Rxg7+ Kxg7 33.Be5+ Qxe5 34.Qxe5+ f6 35.Qe7+ Kg6 36.Qe8+ Kg5 and Black is winning!) ] 27.Be5 And the two bishops are alive. The two attacks on the Nf4 decide the game 27...Re8 28.Rxf5 Rxe5 29.Rxe5 1-0

During the 1960s, Czech Grandmaster Ludek Pachman produced an important series of instructional books that were subsequently translated into English. Modern Chess Strategy, Attack and Defense in Modern Chess Tactics, Modern Chess Tactics: Pieces and Pawns in Action, Open Games, Semi-Open Games, and Indian Defenses formed the foundation of many 1970s English language chess book collections.

I present today all of the games in Pachman's Decisive Games, a collection of more than 100 encounters between 1870 and 1970 that decided major championships and tournaments. Some are brilliancies, some have blunders, but all were dramatic and entertaining.

Here is one game from early in the book, a key game for Paul Keres in the 1956 Candidates Tournament. One point behind Smyslov going into the final round, Keres sacrificed to go on the attack. Here's the game.

Like many chess players, my record with white is much better than my record with Black. As a young player, I struggled to find a defense with which I felt comfortable... something sound and yet capable of offering chances for a win.

If that sounds familiar you might, like me, turn to Andras Adorjan's wonderful book: Black is OK! For Adorjan, playing black is more than a challenge, it's an opportunity to seek to present well prepared, complex lines that reverse white's normal advantage. My favorite chapter, of course, is "The Quill of the Hedgehog," a great title that summarizes the structure's power. Get too close to Black's pawns and you may live to regret it!

Here are all of the games in Adorjan's book and here is one from the chapter on the Hedgehog. It's a very nice illustration of one of the pawn breaks at Black's disposal. Enjoy.

Nc6 would block both the Bb7 and the c-file. From d7, the N can get to e5 (to attack c4)( and c5 (to attack the e-pawn) 11.Nd2 Permitting the exchange of the light-squared bishops, which often serves black well. Instead, white often plays Re1 and e2-e4 first 11...Bxg2 12.Kxg2 0-0 13.Nde4 Qc7 The usual post for the queen, further defending against e4-e5, providing a counter (Qxc4) to Nxd6, and starting the pressure down the open c-file. 14.Rac1 [14.Nxd6 Rad8 15.Nce4 (15.Bf4 e5 16.Nf5 Bc5) 15...h6 16.Bxf6 (16.Bf4 Nh5) 16...Nxf6-+] 14...Rfd8 15.Kg1 h6 16.Nxf6+ Bxf6 17.Bxf6 Nxf6 18.b3 Rac8 Black offered a draw, and Kortchnoi, who has often expressed his disdain for the Hedgehog, turned it down immediately. 19.f3 With the idea of supporting e4 19...Qb8 Typical Hedgehog manoeuvering.

My thanks to all who took part in yesterday's trial of the online, interactive lesson page. I enjoyed it and hope to try again soon. There were no obvious technical glitches with the chat facility, good news as we move ahead.

In the late 1990s, IM Victor Charushin published a neat 5 volume series on tactical themes. Over time, I hope to introduce each of the books in this series. Today, I look at Volume three, Mitrofanovic's Deflection, an imposing title but a neat idea.

In these examples, a piece is sacrificed seemingly for nothing whatever. From the first composition, a study of Mitrofanov's, through real life uses of deflection, the book, and indeed, all the books in the series, provide a quick way to learn.

To make your job a bit easier, I present all of the games in the book as well as Mitrofanov's key composition. In the following diagram, it looks hopeless for white. Just a few scattered pawns against three pieces and a pawn ready to queen. But it's white to move and win!

INVITATION: First public test of the interactive lesson page today at 2 pm (EST)

Irving Chernev was the author of many wonderful chess books. One of my favorites, now well out of print, is The 1000 Best Short Games of Chess.

As a young fellow, I played through many of these games and my copy of the book is now falling apart. Of course, no one wins so quickly without some help. All of these games involve serious mistakes by the loser, but the fact is that the tactics are rich and flowing and full of fun.

Here are most of the games in the book, and here are three examples, all involving quick losses by some recognizable names!

Oskam - Euwe [D00]
Amsterdam Amsterdam, 1920

1.d4 threat 2.e4 1...d5 Queen Pawn Game 2.Bg5 A very unusual move, aiming to develop the dark-squared bishop without blocking it in with e3 2...Bf5 With the same idea 3.Nf3 Nf6 4.c4 e6 Black is fine 5.e3 Diagram

5...h6 But this is an error. dxc4 or simply Be7 are far better 6.Bxf6 Qxf6 7.Qb3 Attacking the undefended b-pawn and adding a second attack on d5 7...Nc6 Under-estimating the danger 8.Qxb7 Kd7 Perhaps expecting Qxa8?? Bb4+ winning the queen 9.cxd5 exd5 10.Bb5! There's no way to prevent Ne5+ winning the Nc6. Even 11.Qxc6 Qxc6 12.Ne5+ is playable. 1-0

Reti - Tartakover [B15]
Vienna Vienna, 1910

1.e4 c6 The Caro-Kann 2.d4 d5 3.Nc3 dxe4 4.Nxe4 Nf6 Known today as the Bronstein-Larsen variation 5.Qd3?! [5.Nxf6+!] 5...e5 An ambitious bid for equality, or more, after white's inaccuracy 6.dxe5 Qa5+ 7.Bd2 Qxe5 8.0-0-0 Bf5 or Be7 are needed. 8...Nxe4 Diagram

It's mate in three! [8...Qxe4 9.Re1] 9.Qd8+ Kxd8 10.Bg5+ double check! 10...Kc7 [10...Ke8 11.Rd8#] 11.Bd8# 1-0

Borochow - Fine [B02]
Pasadena Pasadena, 1932

1.e4 Threatening 2.d4 1...Nf6 Alekhine's Defense. White's main choices are 2.Nc3 and 2.e5! 2.e5 Knights belong in the center of the board where they CANNOT be attacked by pawns [2.Nc3 d5 3.e5 d4 4.exf6 dxc3 5.fxg7 cxd2+=] 2...Nd5 3.c4 [3.d4 is also good] 3...Nb6 4.d4 Establishing a broad center. 4...Nc6?? Diagram

[4...d6 5.f4 is the Four Pawns Attack] 5.d5! winning a piece! 5...Nxe5 [5...Nb4 6.c5 N6xd5 7.a3] 6.c5 Nbc4 7.f4 [7.Qd4 is also very strong] 1-0

INVITATION: Saturday, April 3, 2:00 pm (EST) First public test of the interactive lesson page.

Many thanks to all who commented upon the interactive online chess lesson page. It obviously needs more work, but I'm grateful for all the help and the good ideas!

The most creative grandmaster of all time? That honor undoubtedly goes to David Bronstein, who has the additional distinction of coming as close the the World Championship title as possible without winning it, tying Botvinnik 12-12 in 1951.

Bronstein was the author of 200 Open Games, a compendium of games, mostly his own, all featuring 1.e4 e5. There are King's Gambit's, Petrof's, Scotch Games, but most important, more than 100 games in the Ruy Lopez. The games are not exhautively annotated, but there are some great stories and usually a lesson or two for each game.

Here are all of the games in the book, arranged in ECO order, and here are my notes to one that features an interesting sacrifice in the Ruy.

Bronstein,D - Winiwarter,F [C86]
Krems it Krems, 1967

1.e4 e5 2.Nf3 Nc6 3.Bb5 The Ruy Lopez 3...a6 4.Ba4 White usually prefers to retain the bishop for later operations against the kingside [4.Bxc6 dxc6 5.Nxe5 Qd4] 4...Nf6 5.0-0 Be7 Nxe4 is playable, with a much more open game. 6.Qe2 Re1 is more common 6...b5 7.Bb3 d6 8.c3 The usual idea is d2-d4, Bc2, and Nbd2-f1 8...Bg4 Bg4 works best if white first plays d2-d4 9.h3 Bh5 10.d3 0-0 11.Nbd2 idea Re1, Nf1-g3 11...Na5 12.Bc2 Preserving the bishop 12...c5 13.Re1 Nd7 14.g4 Bg6 15.Nf1 idea Ng3(or e3)-f5 15...f6 16.Ne3 Bf7 17.d4 Re8 Attempting to preserve the closed character of the game. 18.d5 c4 19.b4 Nb7 20.a4 Qc7 21.a5 I would have preferred a slower buildup with Ra3 and Rfa1. 21...g6 Taking away the f5-square. How can white make progress? 22.h4 Kg7 23.Kg2 h6 24.Rh1 Rh8 25.h5 g5 Further sealing the position. 26.Nf5+ Kf8 27.Be3 Rh7 28.Nd2 Part of an interesting plan to sacrifice on c4 28...Bg8 29.f3 Bd8 30.Bf2 Be7 31.Rhc1 Bd8 32.Qf1 Bf7 33.Bd1 Be8 34.Be2 Rc8 35.Ne3 White's pieces are optimally placed for the sacrifice, but does it work? 35...Nb8 Diagram

36.Ndxc4 bxc4 37.Nxc4 idea Nb6 [37.Bxc4 is also strong] 37...Bb5 38.Nb6+- Bxe2 39.Qxe2 Be7 40.Nxc8 Qxc8 41.Ba7 Nd7 42.Qxa6 1-0

April Fool's Day

One of my favorite holidays, a long tradition back to my college days. But there's no joke planned for the BLOG today, just an update on a fun project.

The next advance for Chess is Fun is an interactive lesson page. It will be a place where many can gather online to observe and talk about a game or an opening, or a lesson. The link to the prototype, working though barely, is just above or right here. Permit me to ask that you try it out and provide your comments at our Message Board. Would you prefer to see the chat area beneath the board?

The idea is that I will post a set time for us all to gather. I'm happy to hear your ideas for what we should discuss, though I will need to post the materials before each lesson/discussion.

That's it for today, save that the game currently on display at the interactive lesson page is undoubtedly my best effort. Some have suggested that I post my worst game, but there are far too many candidates to pick from. But it's easy to spot my best effort... do check it out.
