Sport Accord World Mind Sport Games 2011
The first round of the Sport Accord mind sport games in Beijing started with a couple of surprises. Some players appeared to be not completely ready at the start, and that turned out to be costly.
Amrillaev has ended up in a very suspicious classical position. And 8-12? was already the decisive mistake. Black needed to defend himself with ≡ 24-29! 34.42-38 18-22! 35.28x17 21x12 36.43-39 14-20 37.25x14 19x10 38.48-43 13-18 with a slight advantage for white. ≡ 34.42-38! 12-17 Note that ≡ 24-29? is no longer possible due to 35.38-33 29x38 36.30-24 19x30 37.28x17 21x12 38.35x24 W+ ≡ 35.38-33 14-20? A severe mistake, but the position was lost already. For example ≡ 17-22 36.28x17 21x12 37.33-28! 12-17 38.43-38 17-21 39.38-33! 3-8 40.28-22! leads to a positional disaster for black. ≡ 36.25x14 9x20 37.30-25 17-22 38.25x14! 22x42 39.48x37 19x10 40.28x30 and black resigned. An important victory of Valneris against the almost unbeatable Amrillaev!
In the rapid game Boomstra showed his technical skills in a classical game. It is more than likely that in this phase of the game he already spotted the winning 9x9 position after the 47th move. 24-29 35.50-45 29x40 36.45x34 20-24 37.38-33 4-10 38.43-38 17-22 39.28x17 21x12 40.33-28 24-29 41.48-43 29x40 42.35x44 10-14 43.44-40 14-20 44.39-34 20-24? Black is slowly getting into trouble. The black center is too static, and after his last move black is in danger to run out of moves. With the less obvious ≡ 20-25! 45.40-35 3-9 46.38-33 9-14 47.33-29 14-20 48.35-30 20-24 49.29x20 25x14 black could have saved himself from a lot of troubles. ≡ 45.40-35 3-9 46.34-30 9-14? Black has played logical moves, but this turns out to be the decisive mistake. With the difficult to find ≡ 24-29! 47.30-25 29-34!! 48.43-39 34x43 49.38x49 23-29! 50.35-30 9-14! 51.36-31 18-23 52.49-43 12-17 53.27-22 17-21 54.31-27 29-33 55.28x39 13-18 56.22x24 23-28 57.32x23 21x41 black could still make a draw. ≡ 47.43-39! Suddenly the game ended up in a variation of the famous Ricou-Bonnard position. It is well known that white wins after 12-17 48.39-34! etc. ≡ 24-29 48.39-33 29-34 49.30x39 14-20 50.39-34 20-24 51.34-30 23-29 52.28-22 16-21 53.27x16 18x27 54.32x21 26x17 55.37-31 13-18 56.16-11 17x6 57.38-32 29x27 58.31x13 19x8 59.30x19 12-18 60.19-14 18-23 61.14-9 23-28 62.9-3 8-13 63.3-17 and black resigned.
22.33-28? 24x33! Probably Misans totally missed the now following combination from black. 23.28x17 13-18 24.39x28 8-13 25.17x19 14x41 26.31-27 21x32 27.36-31 26x37 28.47x36 10-14 29.42x31 14-19 The number of pieces is equal, but it is clear that white is in a lot of trouble. Not only due to the strong black outpost on 32, but also due to the passive white pieces on the right side of the board. 30.34-30 4-9 31.30-25 9-14 32.44-39 6-11 33.48-42 11-17 34.31-26 20-24 35.39-34 19-23 36.36-31 23-29!! Here ≡ 24-30!? 37.35x24 32-37 was an interesting alternative. But world champion Georgiev has estimated well that white has good opportunities to defend this position, for example 38.43-39 37x48 39.34-30 48x34 40.30x39 16-21 41.39-34 23-28 42.40-35 18-22 43.34-30 14-19 44.24x13 21-27 45.25-20 etc. ≡ 37.34x21 16x36 38.26-21 36-41 39.42-38 32-37 40.21-16 41-46 41.16-11 37-41 42.11-6 24-29 43.38-32 41-47 44.32-27 47-36 45.27-21 36-9 46.40-34 29x40 47.35x44 46-32 48.45-40 32x49 49.21-17 49-32 50.6-1? A mistake in an already lost postion. 32-23! And white resigned.
