World championship match 2013 round 1

It's later than expected, but finally the revenge match for the world title is taking place in the beautiful Estonian town Tallinn, between title defender Alexander Georgiev and challenger Alexander Schwarzman. The system for the match is quite unusual. In seven days a game with normal time controls is being played, if needed followed by a rapid game, a blitz game, and a tie break. So in each of the days a winner will be decided. However, for the final result the games with normal time control still have the highest weight.

In the first game of the match Georgiev challenged his opponent with 17.32-27!? 22-28! Of course Schwarzman grabs the opportunity to attack through the center. 18.33x22 17x28 The structure of the white right wing is far from ideal, so white will have a hard time to put pressure on the black outpost 28. 19.34-30 19-24! Takes the opportunity to gain 6 tempo's. 20.30x19 14x23 21.25x14 10x19 22.38-33 12-17 23.33x22 17x28 24.42-38 8-12 25.47-42 3-8 26.40-34 15-20 27.38-33 For lack of a more constructive plan, Georgiev decides to neutralize the black attack. 12-17 28.33x22 17x28 29.42-38 8-12 30.44-40 20-24 31.34-30 5-10 32.48-42 10-15

33.38-33 24-29 Here black could have continued the attack with ≡ 12-17 34.33x22 17x28 35.42-38 2-7 ≡ 7-12 37.33x22 12-17 and now for example 38.43-38 17x28 39.40-34 9-14 40.38-33 15-20! 41.33x22 20-25 42.45-40! 23-28 43.22x33 24-29 44.34x12 25x43 45.27-22 with a draw. ≡ 34.33x22 29-34 Of course not ≡ 29-33? 35.39x28 23x21 due to 36.31-26 18x27 37.26x6 W+. ≡ 35.40x29 23x25 36.31-26 12-17 37.42-38 17x28 38.38-33! 28-32 Black could not defend the piece with the exchange ≡ 18-22 39.27x18 13x22 due to the combination 40.39-34 28x48 41.45-40 48x30 42.35x4. ≡ 39.27x38 11-17 40.45-40 15-20

In the blitz game Georgiev played a risky attack. The construction of the white left wing looks dangerous, but Georgiev has a lot of experience with it. 15.38-33 14-20! 16.42-38!? Georgiev ignores the development of his left wing. This is extremely dangerous, and in the game he does not manage to repair the damage. 20x29 17.33x24 10-14 18.39-33 7-11 19.44-39 14-20! 20.48-42 With this ugly move white further weakens the left wing. But he did not have an alternative, since both ≡ 20.34-29? 18-23 21.29x7 20x29 22.33x24 8-12 23.7x18 13x35 and ≡ 20.33-29? 18-23 21.29x7 20x29 22.34x23 8-12 23.7x18 13x35 lose immediately, while also ≡ 20.34-30 is prevented by 20x29 21.33x24 25x34 22.39x30 15-20 23.24x15 18-23 24.28x19 13x44 B+. ≡ 20x29 21.33x24 9-14 22.34-30 25x34 23.40x29 17-21 24.38-33 12-17 25.28-23 8-12 26.32-28 3-9

27.42-38? The decisive mistake. With ≡ 27.39-34 14-20 28.43-38 9-14 29.38-32 white could have continued to fight. ≡ 18-22 28.45-40 12-18! 29.23x12 17x8 30.28x17 11x22 The white left wing is paralyzed now, since 31.38-32? is impossible due to the combination 22-27 32.31x22 13-19 33.24x13 9x49 B+ ≡ 31.40-35 14-20 32.35-30 20-25 33.29-23 25x34 34.39x30 9-14 35.23-18(?) 22-28 36.18x20 28x48
