Danger on the Dark-Squares
As an aspiring young player, I heard much about "light-squares" and "dark-squares" but I'm sure that I did not understand. So lets take a BLOG-day and look at an important theme.
Most players are aware of the simple mate with a white pawn on f6 and a white Qh6-g7#. Change the f6-pawn to a Bf6 and the result is the same. Place the same checkmate within a black pawn structure with pawns on f6,g7, and h6 and you can immediately see that white has dominated the dark-squares on the black kingside. Here are two dozen games that involve this theme. All involve a Q(x)h6 sacrifice that succeeds in most (but not all) of the games. I hope that you play through at least the following two games if not all of the games in this small collection. You may find that your chess improves as a result. You'll certainly begin to see the connection between some fun chess concepts, dominating the center with e4-e5, forcing black to weaken te kingside with g7-g6, and taking advantage of the dark-square weaknesses that result.
