Round 9 World Cup Ufa

The world cup was won by Alexander Getmanski, who managed to beat Kolesov in the last round. The second place was for the Dutch talent Boomstra.

After 18-23? Getmanski missed the relatively easy win using 47.31-26! 12-18 48.36-31 18-22 49.32-28 23x32 50.31-27 22x31 51.26x28 W+. ≡ 47.42-38 This is probably winning also, but it is much more complicated. 21-26 48.32-27 26x37 49.38-32 37x28 50.33x11 12-17 51.11x22 24-29 52.39-34 29x40 53.35x44 23-29 54.22-17 29-33 55.17-12 33-38 56.12-7? 38-42 57.7-1 42-47 58.44-39 47-42 59.1-45? 42-37 60.27-21 19-24 61.21-16 37-26 62.39-33 24-30 63.25x34 26-17 64.33-29 14-19 65.45-50 17-26 66.50-28 19-24 67.28-33 26-48 68.29-23 48x30 69.23-18 30-34 70.18-13 34-29? The decisive mistake. With ≡ 24-30 71.33x15 34-1!! (and not ≡ 30-35? 72.15-33! 34-1 73.33-6 35-40 74.13-8 W+) black could still make a draw. ≡ 71.33-50! and white won.

Tsjizjow locked up the black center using 36.32-27! 22x31 37.36x27 17-22 38.44-40! 22x31 39.26x37 It is clear that black is in big trouble, since black has only 2 movable pieces on the left side of the board against 3 pieces of white. 8-12 40.37-31 12-17 41.42-37 7-11 42.37-32 10-14 43.31-26 11-16 44.48-42 4-9? Now it is lost for black. With ≡ 17-22 45.32-27 22x31 46.26x37 16-21 47.37-32 21-26 48.42-37 14-20! 49.15x24 4-10! a draw was still possible. ≡ 45.42-38 17-22 46.32-27 22x31 47.26x37 16-21 48.38-32 21-26 49.30-25 19-24 50.29x20 18-22 51.34-30 22-27 52.32x21 26x17 53.30-24 23-28 54.24-19 13x24 55.20x29 17-22 56.40-35 22-27 57.29-23 28x19 58.25-20 14x25 59.15-10 W+

With 49.43-38? Gulyaev gave his opponent a chance to relieve the pressure with 18-23! 50.38-32 30-35 51.22-17 35x44 52.39x50 20-24. Instead ≡ 49.33-28! was winning, since 30-35? fails due to 50.28-23 35x33 51.23-19 13x24 52.22x2 W+. ≡ 30-35? 50.38-32! 35x44 51.39x50 20-24 52.45-40 18-23 53.40-35 13-19 54.33-29(?) Here ≡ 54.35-30 24x35 55.33-29 was easier. ≡ 24x33 55.22-18 23-28 56.32x14 12x23 57.14-9 33-38 58.9-3 8-12? 59.3x17 38-42 60.17-28 23x32 61.27x47 16x27 62.50-44 W+

After 38.37-32 26x37 39.42x31 8-13! Amrilloew had a substantial advantage due to the inflexible white center. 40.48-42(?) It was probably better to play ≡ 40.31-26 here. ≡ 14-19! 41.31-27 18-23 42.27-22 15-20? With ≡ 9-14! 43.22x11 16x7 44.36-31 7-11 black could force his opponent into a lost classical position. ≡ 43.22x11 16x7 44.25x14 9x20 45.36-31? Here Tolchikov should have played ≡ 45.28-22! The main difference with the game is that after 20-25 46.42-37! black can not play 7-11? Because of that it is not possible for black to keep the white left wing locked up. ≡ 20-25 46.31-27 21-26 47.42-37 3-8 48.28-22 7-11 49.33-28 25-30 50.38-33 23-29 51.37-31 29x38 52.32x43 26x37 53.27-21 37-41 54.43-39 41-47 B+
