In the first game Ivanchuk, playing with the White pieces, obtained only a small advantage after the opening, but a mistake by Shirov led to a difficult position for Black.

1.e4 c5 2.Nf3 Nc6 3.Nc3 e5 4.Bc4 Be7 5.d3 d6 6.0-0 Nf6 7.a3 Be6 8.Ng5 Bxc4 9.dxc4 0-0 10.b3 Nd4 11.Bb2 a6 12.a4 Qd7 13.Qd3 Bd8 14.Kh1 Ba5 15.Nd5 Nxd5 16.exd5 Qf5 17.Ne4 Qg6 18.g4

18...Bd8? The mistake by Shirov. 19.f4! With this move Ivanchuk got a clear advantage, then a strong attack, and finally an easily winning endgame with queen against two rooks. 19...Qxg4 20.Nxd6 exf4 21.Bxd4 cxd4 22.Nf5 Qh5 23.Rxf4 g6 24.Qxd4 gxf5 25.Rg1+ Bg5 26.Qf6 h6 27.Rxf5 Kh7 28.Rfxg5 hxg5 29.Rxg5 Qxg5 30.Qxg5 f5 31.d6 f4 32.d7 f3 33.Qe7+ Kh6 34.Kg1 Rg8+ 35.Kf2 Raf8 36.c5 Rg2+ 37.Kf1 Rgg8 38.Qh4+ Kg6 39.Kf2 Rh8 40.Qe4+ Kg5 41.h4+ Kh5 42.Qxb7 Kxh4 43.Qe4+ Kg5 44.Qe5+ Kg6 45.c6 1-0.

In the second game Shirov repeated his well-known game against Anand, in the Najdorf variation, from Linares Morelia 2008, but Ivanchuk did not play 12…Rc8, preferring 12…Be7. At first White's attack looked promising, but with several strong moves, Ivanchuk demonstrated that his attack was faster, and gained big material advantage, so Ivanchuk obtained a critical advantage of 2-0.

The third game followed Carlsen-Shirov from Linares/Morelia earlier this year. Ivanchuk varied with 18.Kh1 instead of 18.Ra6. The game was about equal after the opening, however Shirov tried very hard to win, and even with very few pieces he came very close.

Black has set up a mating threat (starting with ...Bg3). The best way to defend is 55.Rf7 Bg3 56.Bd7+ Kc5 57.Rxf3. First the rook, then the bishop. 55.Bd7+? Kc5 56.Rf7. Now 56...Rf1 wins: 57.Kf2 Bd4+ 58.Kg3 (58.Kxf3 Rf1+ 59.Kg4 Rxf7) 58...Rg1+ 59.Kh2 f2+–. Unfortunately one of the greatest endgame artists missed it. 56...Bf4? and the game will be drawn. 57.Bg4 f2 58.Rd7 Be3 59.Rd1 Bd4 60.Bf3 Rb3 61.Kg2 Rb2 62.Kf1 Rb6 63.e5 Re6 64.Rc1+ Kb6 65.Rc4 Bc5 66.Re4 Re7 67.Be2 Ra7 68.Kg2 Ra1 69.Bf1 Re1 70.Re2 Kc7 71.e6 Kd8 72.e7+ Ke8 73.Rc2 Re5 74.Re2 Rf5 75.Re4 Bxe7 76.Re2 ½-½.

In the last game Shirov wanted to play for a win, but Ivanchuk got a decent position right after the opening, and the game finished in a draw by repetition of moves. In the press conference Ivanchuk mentioned several interesting lines of the games, the majority of them best lines suggested by Fritz 11. Shirov was satisfied with the interesting games he had played in the match.
