Game 8: Anand played 17. Qf2!, which trapped Gelfand's queen, resulting in immediate resignation from black.Anand started the game with the same play as in the third game, but Gelfand early deviated by playing 3 ...c5 instead of 3 ...d5, which was seen in the game 3. The game was followed with 4.d5 d6 5.e4 Bg7 6.Ne2 O-O 7.Nec3 Nh5. Gelfand tried to provoke g4 by playing 7 ...Nh5, but Anand did not opt for that line. But after few moves the Black bishop occupied the f5 square and let White the opportunity to play 12.g4 with a fork on the Black's bishop and knight. The game continued with 12 ...Re8+ 13.Kd1 Bxb1 14.Rxb1.[35] Gelfand made a serious error on move 14, overlooking Anand's 17 Qf2, which trapped Gelfand's queen. This idea was also missed by grandmaster commentators Peter Leko and Ian Nepomniachtchi, who preferred Black's position until Anand played 17 Qf2.[36] Gelfand could have saved his queen by sacrificing his knight with 17...Nc6, but his position was still lost.[35]
At only 17 moves, this was the shortest decisive game in World Championship history.[37]
