SWMG 2011 round 2

Alexander Getmansky - Alexander Georgiev 0-2
Alexander Getmansky - Alexander Georgiev 0-2

In the rapid game against Getmansky, Georgiev took a strategic exchange with 24-29! 21.33x13 22x33 22.38x29 1-7 23.13x22 17x26 Clearly black has a long term advantage now. The white left wing is dangerously weak, and there are zero chances for white to put pressure on black's solid left wing. 24.43-38 12-18 25.44-39 7-12 26.39-33 11-17 27.42-37 17-22 28.50-44(?) This makes it possible for black to activate the piece on 14. With   28.30-24! white should have prevented this.   14-19! 29.38-32 9-13 30.49-43 10-14 31.43-38 19-23 32.30-24 21-27 33.32x21 16x27 34.24-19(?) White loses a lot of terrain with this exchange. But one can imagine that he did not trust   34.34-30 23x34 35.30x39 18-23 36.37-32 13-18 37.32x21 26x17 either.   13x24 35.29x9 3x14 36.44-39 5-10 37.35-30 4-9 38.48-42 27-31! 39.36x27 22x31 Black prepares a break-through on the white left wing. 40.38-32? White still had a narrow escape with   40.33-29! 31-36 41.30-24 9-13 42.38-32! 26-31 43.37x26 36-41 44.32-27! 41-47 45.39-33 47x16 46.24-19 13x24 47.29x9.   31-36 41.32-27 12-17 42.30-24 26-31 43.37x26 36-41 44.42-37 41x21 45.24-19 It looks like Getmansky found an escape, but Georgiev has looked deeper: 21-27! 46.19x28 18-23! 47.28x19 14x23 The remaining 5 against 5 position is hopeless for white 48.34-30 10-15 49.39-34 27-32 50.33-29 23-28 51.30-24 32-37 52.34-30 9-13 53.24-20 15x35 54.25-20 37-41 55.29-24 41-46 and white resigned.

Zhou Wei - Roberts Misans 0-2
Zhou Wei - Roberts Misans 0-2

The inexperienced Chinese player Zhou Wei is performing very well in the games with normal time controls. But in games with faster time controls he turns out to be more vulnerable: 17.42-38? 14-20! This brings the threat 18-23 29x18 20x29 34x23 21-27 31x22 17x19 into play. Therefore white sacrificed a piece with   18.29-23 20x29 19.37-32, but after 21-27 20.31x13 8x37 21.34x23 37-42 it became clear that this sacrifice was permanent. Misans had no difficulties to convert the game to a win.

Zoja Golubeva - A La Tenghua 2-0
Zoja Golubeva - Alatenghua 2-0

In the women's tournament Golubeva immediately took the lead with two victories. White has locked the black right wing using an economic fork formation. 19-24! Black needs to find expansion on the other side of the board. 31.49-44 13-19 32.44-40 2-8? It seems logical to develop the piece on 2 towards the center. But after this move black is in big trouble. With   2-7! 33.48-42 20-25 34.39-34 23-29 35.34x23 19x28! 36.32x23 18x29 37.27x18 12x23 black had better opportunities for making a draw.   33.39-34! 8-13 34.43-39 20-25 35.48-43 24-29? Now the game is definitively over. The best chance for black to escape was to create complications with the piece sacrifice   24-30 36.35x24 19x30 37.34-29 23x34 38.40x29 22-28 39.32x23 17-22! Then it is not immediately clear how white can win the game.   36.35-30 29-33 37.38x29 22-28 38.43-38 17-22 39.29-24 11-17 40.24-20 6-11 41.20x9 13x4 42.30-24 19x30 43.40-35 28-33 44.39x19 30x39 45.19-13 18x9 46.27x7 11x2 47.45-40 9-13 48.31-27 and black resigned.
