In 1978, Anatoly Karpov "prepared" for his coming World Championship match by taking part in the strongest 16-player chess tournament ever held. All 16 players were grandmasters with an average ELO rating of 2588 (Category 14).

Timman defeated Karpov early in the tournament, but the world champion recovered by winning 6 of his remaining games to tie Spassky for first place. This was Karpov's tenth first prize in the 12 tournaments in which he competed since becoming claiming the world championship from Fischer (the match that never occurred). Bugojno was the second in his remarkable streak of 9 consecutive tournament wins.
Don't miss Karpov's beautiful win in Round 12 against Vlastimil Hort.
The games of Bugojno, 1978
Bogojno 1978 was not only one of the strongest-ever chess tournaments, it may have produced more different postmarks than any other tournament.
A total of 14 different postmarks were produced during the tournament, not quite one for each of the 15 rounds in the tournament. The postmarks exist as both machine and hand cancels. I present a complete set of registered covers from the tournament. Note that 4 additional cancels were produced in Bogojno in the months just prior to the beginning of the tournament.
