In this equal position Buzinskij played carelessly 6-11? 39.31-27! 22x31 40.36x27 9-13 What else? 41.26-21! 17x26 42.27-22 18x27 43.32x21 26x17 44.33-29 24x33 45.38x16 Nevertheless the position is still a draw. 10-14 46.43-38 13-18 47.42-37 18-22 48.38-32 14-20 49.37-31 19-23 50.32-27 22-28 51.27-22 28-33? This piece goes in the wrong direction. After ≡ 28-32 52.22x11 23-29 53.34x23 25x34 a draw was still possible. In a few moves it will become clear why the 51st black move was an unfortunate one. ≡ 52.22x11 23-29 53.34x23 25x34 54.35-30! 34x25 55.11-7! 25-30 56.7-1! 30-35 The problem for black is that after ≡ 30-34 57.23-19! 34-39 58.1-6 his front pieces are blocked, and after 20-25 59.19-13 25-30 60.13-8 30-35 61.8-3 35-40 62.3-12 40-45 63.12-29 33x24 64.6x50 white is just in time. If Buzinskij had played 28-32 on the 51st move, then now he had the possibility to cross the diagonal with 30-34. ≡ 57.23-18? Now that Schwarzman is almost there he picks the wrong move. It turns out that ≡ 57.1-6 33-38 58.6-44 was winning. But for humans the subtle differences between those moves are very difficult to calculate. ≡ 35-40! Buzinskij claims the important square 45, and this guarantees him a narrow escape. 58.1-6 33-38 59.18-13 40-45 60.13-9 38-42 61.6-50 42-48 62.31-26 20-24 63.9-4 24-29 64.4-22 29-34 65.22-44 48-42 66.16-11 42-24 67.44-40 24-29 68.40-49 29-24 69.11-7 24-35 70.26-21 34-39 71.50x6 35-8 72.21-16 45-50 73.7-2 8-17 74.6x22 50x17
After 33.27-22? Meurs won the game in a very instructive way. 18x27 34.31x22 8-12! 35.48-42 11-17 36.22x11 16x7! 37.36-31(?) After ≡ 37.38-33 12-18! 38.42-38 black can play a probably winning Ghestem attack with 23-29 39.36-31 18-23. ≡ 3-8 38.43-39 13-18 39.39-33 8-13 40.40-34 4-9 41.34-29 23x34 42.30x39 7-11 43.31-27 11-16 44.28-23 Silva sacrifices a piece, because after ≡ 44.28-22? 19-23! white cannot play 45.39-34 due to 24-30 46.35x24 23-28 47.32x23 18x40 B+ ≡ 18x29 45.32-28 12-18 46.39-34 29x40 47.35x44 18-23 48.37-32 13-18 49.44-40 9-13 50.40-35 26-31
The computer program Kingsrow showed that Ndjofang could play the unexpected move 12-17! Then both combinations 26.27-22 18x27 27.32x1 and ≡ 26.28-22 17x28 27.32x1 fail due to 13-18! 28.1x20 14x21. And thus white has to retreat with ≡ 26.28-23 18x29 27.27-22 17x28 28.32x34. The game ended in a draw after ≡ 18-23.
