I will be starting a series of top 10 lists. This one is the top 10 blunders in the history of chess. I am interested to hear your comments - maybe you might disagree with the blunders and the order. Enjoy!
BLUNDER #10: Reshevsky-Savon 1973
Here, white is down a piece, but he has managed to use his major pieces to hunt out the black king. In fact, he has a mate in 3 with 40. g5+ Kxg5 41. h4+ Kxh4 42. Qf4#. White has 4 other moves that mate soon, and 2 other moves that maintain at least a rook's worth advantage. Reshevsky, however, announced mate with 40. Qxg6+. He missed the bishop on b1, and resigned after 40... Bxg6. Reshevsky was in time pressure.
BLUNDER #9: Taimanov-Fischer 1971
Taimanov had already lost the first four games of this match. This endgame is drawn, but Taimanov was already discouraged by losing four games in a row. He managed to lose again with 46. Rxf6??. After 46... Qd4+ Taimanov resigned, as the rook is lost. After 47. Rf2 comes 47... Ral+.
BLUNDER #7: KARPOV-BAREEV 1994
Here is another easily drawn position. Bareev pictured the variation 35... Rxd5 36. Nxd5 Ba7. He played it - but mixed the move order up! After the terrible 35... Ba7?? white mated with 36. Rxd8#. Note that 35... Ba7?? is the only move on the board to allow a mate in one!
BLUNDER #6: CHIGORIN-STEINITZ 1892
This is a crucial game in the world championship match. Steinitz sacrificed a piece to get 2 rooks on the seventh, but Chigorin is winning. Instead of playing the obvious (and good) 32. Rxb7, Chigorin had a major oversight and played 32. Bb4??. After 32... Rxh2+ white resigned. After 33. Kg1 would come 33... Rdg2#.
BLUNDER #5: POPIEL-MARCO 1902
This blunder is not like the others. In this position, black's bishop is pinned. Black, however, had the opportunity to win the queen with 36... Bg1!. The queen would be attacked, and mate would be threatened on h2. Instead, what did Marco do? He resigned! This is the earliest example of premature resignation.
BLUNDER #4: SHORT-BELIAVSKY 1992
Have you ever heard of the saying "Nigel Short?" This means a bizzare mate in the endgame with limited pieces. This is the game that saying came from. Here, white could win with 58. Nxf6. Instead, Short came up with 58. Ke6??. A crazy mate occurs after 58... Bc8#!
BLUNDER #3: CHERNIAEV-CONQUEST 2004
In this position, white should win, but the win is not easy at all. The players have been playing for a long time, and are exhausted. Maybe that explains 87... Ke6??. Another "Nigel Short" mate occurs after 88. Bf5#! ==========================================================
BLUNDER #2:PETROSIAN-BRONSTEIN 1956
BLUNDER #1: DEEP FRITZ (COMPUTER) - KRAMNIK 2006
In this position, a draw would result after 34... Kg8. Kramnik, however, made the worst blunder in the history of chess. 34... Qe3?? Kramnik made this move and went to take a walk. After he came back, he was shocked that he had been mated by 35. Qh7#! The spectators were equally surprised.
That's my list. Please comment, and what is your opinion? Do you think there are better ones? Do you think the order is wrong?
