Here are some games from the past up to a few years ago: The five games between Botvinnik and Keres were remarkable because they have to be the worst series of five games ever played between two grandmasters. Even the strongest grandmaster will occasionally make a horrible blunder. However, these games between Keres and Botvinnik did not merely contain a few outright blunders. Rather, they exuded weakness throughout. They looked like games between two Class A players, or possibly between two experts having a bad day. However, Keres and Botvinnik were two of the strongest players in the world. By far the worst game of the five was the last game, in which Botvinnik lost to Keres. Keres played a patzer opening, always known to be bad. Botvinnik played like an absolute rank beginner. The presumed reason: Botvinnik had already clenched first place and the World Chess Championship. Since Keres had thrown the first four games to Botvinnik, Botvinnik was obliged to throw one back to make the final result of 4-1 in favor of Botvinnik look more reasonable. Consider the third game, which was as follows: [Event "1948 World Championship Match-Tournament"] [White "Keres Paul "] [Black "Botvinnik M "] 1.d4 e6 2.e4 d5 3.Nd2 c5 4.ed5 ed5 5.Ngf3 a6 6.dc5 Bxc5 7.Nb3 Ba7 8.Bg5 Nf6 9.Nfd4 O-O 10.Be2 Qd6 11.O-O Ne4 12.Be3 Nc6 13.Nxc6 Bxe3 14.fe3 bc6 15.Bd3 Nf6 16.Qe1 Ng4 17.Qh4 f5 18.Rf4 Ne5 19.Qg3 Ra7 20.Raf1 Raf7 21.Nd4 Nxd3 22.cd3 c5 23.Nf3 Qb6 24.Rh4 h6 25.Ne5 Rf6 26.d4 cd4 27.Rxd4 Qxb2 28.Rxd5 Be6 29.Rd4 Kh7 30.Nd7 Bxd7 31.Rxd7 Rg6 32.Qf3 Qe5 33.Rd4 Rb8 34.Qf4 Qe6 35.Rd2 Rb5 36.h3 Re5 37.Kh2 Rf6 38.Rfd1 Re4 39.Qb8 Rxe3 40.Rd8 Qe5 41.Qxe5 Rxe5 42.R1d2 g5 43.g4 Rf7 44.R8d7 Kg7 45.gf5 Rxf5 46.a3 Rf2 47.Kg3 Rxd7 48.Rxd7 Rf7 49.Rd4 Rf6 50.a4 Kg6 51.h4 Kh5 52.hg5 hg5 53.Rd3 Rf4 54.Ra3 a5 55.Kh3 Rb4 56.Kg3 Rf4 57.Ra1 Rg4 58.Kh3 Re4 59.Ra3 Kg6 60.Kg3 Kf5 61.Kf3 Ke5 62.Kg3 Rd4 63.Ra1 Kd5 64.Rb1 Rb4 65.Rf1 Ke5 66.Re1 Kd4 67.Kh2 Rxa4 68.Rg1 Rc4 69.Rxg5 a4 70.Kg2 Kc3 71.Kf3 a3 72.Ra5 Kb3 0-1 There were a lot of bad moves in this game. Botvinnik missed an outright win with 28. ... f4, because of 29. exf4 Rxf4 30. Rxf4 Qc1+ followed by checkmate. After that, the game boiled down to a clear draw, but Keres generously gave away a pawn for no particular reason. After move 52, the following position was reached: White pieces: Pawn on a4, Rook on d4, King on g3 Black pieces: Pawn on a6, Rook on f6, Pawn on g5, King on h5 Although White is a pawn down, this is a standard textbook drawn position. This position has occurred, in minor variations, tens of thousands of times. Every tournament chess player, while working his way up, finds it necessary to learn certain basic positions. This is one of those positions. Every player, by the time he has reached about 1600 in chess strength, should be expected to know this position cold. The drawing technique is simple. White leaves his rook on the fourth rank. Eventually, to make progress, Black must advance his pawn to g4. White then must immediately move his rook to the eighth rank and start checking from behind. The Black king cannot escape the checks and the game is a draw. What did Keres do? He made a move that even a 1600 player would be embarrassed to make. He retreated his rook back to d3, allowing Botvinnik to seize the fourth rank with 53. ... Rf4. The game was still probably not completely lost, but a few more bad moves by Keres caused the game to be lost. Anybody can make a blunder. However, when a player blunders, almost always there is a reason. What possible reason could Keres have had for playing a move like 53. Rd3? The answer is obvious. He was a human. http://www.chessbase.com/columns/column.asp?pid=150
