Draughts analysis by Wieger Wesselink

Georgiev,A. - Schwarzman,A. 0-2 2009.06.21

In the second micro match we immediately jump to the decisive 5th game. At the start of this game Georgiev had a significant advantage on the clock. But it was Schwarzman who took the initiative, and after Georgiev chose a very risky plan in the middle game, Schwarzman finished the game in great style. And so he defended his world title successfully.

Schwarzman has come out of the opening with some advantage. The black position is very compact and has no weaknesses, while white has an inproductive piece on 26.

23.27-21 24-30 24.35x24 20x29 25.33x24 19x30 26.38-33 30-35 27.42-38 35x44 28.49x40 13-19 29.40-34 15-20 30.47-42 8-13 31.45-40 20-24 32.40-35 14-20 33.34-30 20-25 34.39-34!?

Georgiev decides it's time to gamble. He allows Schwarzman to lock up his right wing, and searches for complications. Especially for white this is an adventure with an uncertain outcome.

9-14 35.32-28 23x32 36.37x28 2-8 37.42-37? White brings the threat 38.28-23 19x48 39.30x10 into play. With this he forces black to do a concession on the 39th move. But as GMI Alexei Tsjizjov explains on the Shashki Forum, Georgiev missed a good opportunity in this position. After 37.41-37! 14-20 (and not 18-23? 38.34-29! 23x41 39.29x18 25x34 40.42-37 W+) the white position is preferable after 38.37-32 or (especially) 38.38-32!. A variant to illustrate this is 7-11 39.21-16 1-6? 40.16x7 12x1 41.32-27 1-7 42.37-32! 18-23 (the alternatives aren't any better, for example 8-12? 43.42-38 7-11 44.27-22! 18x27 45.32x21 W+, or 7-12? 43.27-21 18-23 44.32-27! 23x32 45.27x38 and the white strategy becomes a success) 43.43-38! 6-11 (what else?) 44.27-22 24-29 45.33x15 19-24 46.30x19 13x24 47.28x30 17x48 48.15-10 11-16 49.10-5 16-21 50.26x17 48-26 51.17-11 7x16 52.30-24 with a promising position for white.

On the Shashki Forum a user named W.W.O. notes that after 39.21-16 black can immediately force a draw using 19-23! 40.30x19 (not 40.28x19? due to 17-22 41.16x7 22-28 42.33x22 18x47 43.7x9 24x4 B+) 23x14 41.16x7 17-22 42.28x17 12x21 43.26x17 1x21. This probably means that the position after 37.41-37 has to be considered equal, although a thorough analysis is needed to confirm this.

18-23 38.21-16 23x32 39.37x28 14-20 40.38-32 13-18 41.41-37 18-23 42.37-31 12-18 43.31-27 8-13! (not 7-12? due to 44.16-11! 17x6 45.28-22 8-13 46.22-17!! 12x21 47.26x171-7 48.17-12 7-11 49.32-28! 23x21 50.12x14 20x9 51.30x8 W+).

44.27-21 7-12 45.32-27 23x32 46.27x38 18-22

Here white could still escape using the sacrifice 47.16-11! 17x6 48.38-32, since if black plays 22-27 then white replies with 49.32-28 27x16 50.28-23 19x48 51.30x17 48x30 52.35x15.

47.38-32? 1-7 48.32-28? And after this move it is all over for white. Only with the sacrifice 48.43-38 13-18 49.16-11 7x27 50.32x21 white could keep fighting for a draw.

13-18 49.43-38 19-23! and not 18-23? 50.38-32! 22-27 or? 51.28-22! 27x40 52.22x2 25x34 53.35x44 with a draw.

50.28x19 24x13 51.33-29 13-19 52.38-33 20-24! 53.29x20 25x14

Two small combinations bring Schwarzman the victory. White can not play 54.30-25? due to 14-20 55.25x23 18x38 B+. And since 54.33-29? 22-28! is hopeless white has nothing better than to allow the following combination.

54.34-29 7-11! 55.16x7 12x1 56.21x23 19x39 57.30-25 39-43 58.29-24 43-48 59.25-20 14x25 60.24-19 22-27! The white piece on 19 cannot proceed, and after another piece sacrifice 61.26-21 27x16 62.19-13 48-37! Georgiev resigned.
