World Championship 2011 round 1
After 14-20(?) Mogilianski replied with the unexpected attack 33.33-29! 24x33 34.38x29 19-23 35.29-24! 20x29 36.30-25 13-19? It was necessary to defend actively with ≡ 29-33! 37.43-39 33x44 38.40x49 13-19 39.35-30 17-21! 40.26x17 11x22 etc. ≡ 37.25-20 29-34 38.40x29 23x34 39.42-38 17-21 40.26x17 11x22 41.20-15 19-23 42.15-10 23-29 43.41-37 18-23 44.47-41 and black resigned.
Here Dul made a big mistake with 9-13?? but he was not punished for it. After 42.28-23 8-12 43.34-30 white simply wins a piece. ≡ 42.34-30? 20-25 43.30x19 13x24 44.29x20 15x24 45.39-34 8-13 46.34-29 13-19 47.29x20 25x14 48.43-38 21-27 49.33-29?? And now he even gets both points. Silva could make an easy draw using ≡ 50.35-30 18-23 51.33-29 22x35 52.31x11. ≡ 22x42 50.31x24 42-47 51.29-23 47x20 52.35-30 20-42
Van der Wijk's position is passive, but not worrying yet. 40.36-31(?) 8-13! This introduces the threat 23-28 and 12-17. 41.33-28? After ≡ 41.31-26 a draw is the most logical result. In the game Boomstra demonstrates his superior technique. ≡ 14-19! 42.31-27 20-24 43.40-34 15-20 44.34-30 The white position is lost. After ≡ 44.38-33 black plays 1-6! ≡ 23-29! 45.39-34 29x40 46.35x44 24x35 47.43-39 19-24 48.39-34 20-25 49.38-33 13-19 50.34-29 1-7 51.29x20 25x14
Gantwarg had a very good position, but with 3-8? he gave Meurs an opportunity to escape using 40.34-29! 23x34 41.47-41 36x29 42.28-23 19x28 43.32x3. Better was ≡ 36-41 40.47x36 24-29 41.33x24 19x39 42.28x10 4x15 with good opportunities to win the game. ≡ 39.42-38 8-12? A better plan for black was ≡ 17-22 40.28x17 24-29 41.33x24 19x39 ≡ 40.47-42? White could make an easy draw with the standard maneuver ≡ 41.27-22 18x27 42.32x21 23x41 43.34-29 17x26 44.29x7. ≡ 36-41! 41.37x46 24-30? With ≡ 24-29 42.33x24 19x39 43.28x8 12x3 black could probably win the game. ≡ 42.35x24 19x39 43.28x8 39x48 44.8-3 14-20
