World championship match 2013 round 2

Schwarzman - Georgiev 1-1
Alexander Schwarzman - Alexander Georgiev 1-1

The game with normal time control ended in a draw. 32.37-32 14-20 Here   12-18 was not really an alternative, because white can play 33.32-27 followed by the exchange 29-23 18x29 34x23 to bring all his pieces into play.   33.29-23 16-21 34.23x14 20x9 35.34-29 It was also possible to advance to 17 with   35.22-17 11x22 36.28x17, since black cannot attack the piece with 12-18? 37.17-11 6x17 38.36-31 26x28 39.33x11 W+   12-18 Georgiev decides to force a draw, which is indeed the most sensible plan in the defensive black position. 36.29-24 18x27 37.28-22 27x18 38.24-19 13x24 39.36-31 26x28 40.33x2 9-13! Of course both players had calculated this king capture in advance. 41.2x9 4x13 42.40-35 13-18 43.39-34 6-11 44.34-29 24x33 45.38x29 11-17 46.42-37 18-22 47.29-23 3-9 48.48-43 17-21 49.43-39 21-26 50.39-34 22-27 51.23-18 27-31 52.37-32 31-36 53.18-12 36-41 54.12-7 41-46 55.32-27 46-23 56.7-1 23x45 57.1-6 9-13

Georgiev - Schwarzman 1-1
Alexander Georgiev - Alexander Schwarzman 1-1

In the rapid game Georgiev had some advantage in a classical game, due to the tempo difference of -5. In closed classical positions like this it is usually a disadvantage to have the lead in tempo's. 42.34-30 25x34 43.39x30 8-12 44.45-40 21-26 45.48-42 23-29?! May be Schwarzman did not trust the normal continuation   9-14 46.42-37 17-21 47.43-39 12-17 48.40-34 which results in the famous position Ottina-Weiss:

Ottina - Weiss 1-1 (1910)
Ottina - Weiss 1-1 (1910)

In that game black lost after 17-22? 44.28x17 21x12 45.33-28 23-29 46.34x23 18x29 47.30-25 etc. But with the temporary piece sacrifice   24-29! 44.33x24 17-22 45.28x17 21x12 black can make an easy draw. In the game it turned out that Schwarzman's 45th move was entirely correct. There is no way for white to take advantage of it.   46.42-37 18-23 47.30-25 9-14 48.43-39 13-18 49.40-34 29x40 50.35x44 17-21 51.28-22 12-17 52.22x13 19x8 53.33-28 14-19

After a draw in the blitz game the tie break with 2 seconds added time per move had to bring a decision. In the second game Schwarzman played very agressively.

Schwarzman - Georgiev 0-2
Alexander Schwarzman - Alexander Georgiev 0-2

16.37-31!? 26x37 17.42x31 8-12 18.30-24 3-8 19.31-26 14-20 20.33-29!? A dangerous move, since it locks up the white right wing. 21-27 21.48-42 10-14 22.38-32 27x38 23.43x32 2-7! With an unconventional move Georgiev disrupts the white strategy. Schwarzman is now forced to play 24.32-28, which was probably not what he had in mind. After the logical   18-22 24.36-31! white would have taken control over the left side of the board. That control would be enough to compensate for the immobile white pieces on 35 and 45.   18-22! Black develops his pieces towards the understaffed white left wing. 25.28-23 13-18! 26.42-37 9-13 27.49-43 Here the game ended abruptly, because Schwarzman lost on time. The position looks better for black, for example with the exchange 14-19 28.23x14 20x9 he can try to take advantage of the rigid white right wing.
