Getmanski underestimates the power of the Ghestem attack 36.28-22! 23-29 Since after 8-12? 37.22-17! black is the victim of a terrible 'zugzwang'. 37.44-40 18-23 38.33-28 8-12 39.39-33 6-11

Boomstra - Getmanski 1-1

40.35-30? Boomstra cannot resist the combination that leads to an endgame with a piece advantage. However, it turns out that it is not enough for a win. Instead the backwards exchange 40.40-34 29x40 41.35x44 was hopeless for black. The main variant is 23-29 42.44-40 13-18 43.22x13 19x8 44.48-43 8-13 45.43-39 11-17 46.39-34! 13-18 47.34x23 18x29 48.27-22!

Valneris - Mogilianski 1-1

Here Valneris played 52.24-20? At first sight this looks winning, but it turned out that black can make a draw in the resulting endgame with two pieces less. The endgame 52.29-23! 13-18 (note that 21-27? 53.32x12 13-18 54.28x17 18x38 55.12-7 38-43 56.24-20! is not possible) 53.23x12 17x8 54.28x17 21x12 55.24-20 would have given much better opportunities. 14-19 53.29-23 25x14 54.23-18 14-20 55.18x16 20-24 56.31-27 24-29 57.33x24 19x30 58.27-21 17-22 59.28x17 13-18 60.32-27 30-34 61.16-11 34-39 62.11-7 39-44 63.21-16 18-23? The draughts program Kingsrow indicates that this is a losing move. After 44-50! it was still a draw. 64.7-2 23-29 65.2-30 44-50 66.27-22 50-44 67.16-11? But after this move the white pieces are too vulnerable. White should have waited with 67.30-25 44-50 before playing 68.16-11. Then the black king is out of position on square 50. 44-35! Mogliljanski grabs his chance and finds a magnificent escape 68.30-48 35-19 69.48-42 19x41 70.42x15 41-14 71.22-18 26-31 72.11-6 31-37 73.15-47 14-3 74.18-12 3-9 75.12-8 9-36 76.8-3 37-41 77.17-12 41-46 78.6-1 36-18 79.12x23 46x5 80.1-12

The white left wing has become too weak. 44.39-33 31-36 45.41-37 27-32 46.28-22 32x41 47.22-17 41-46 48.17-11 2-7 49.11x2 14-20 50.2x19 46x5
