World championship 2013 preliminaries round 1

Golubeva - Schwarzman 0-2 (2013)
Golubeva - Schwarzman 0-2 (2013)

Golubeva played 17.31-26 in an attempt to develop the piece on 36. This gave Schwarzman the opportunity to complicate the game with 18-23! 18.26x17 11x22 19.28x17 23-29 20.34x23 19x37 21.40-34!? Here   21.33-28 was much safer   7-11! 22.38-32 37x28 23.33x22 14-19! Brings the threat 24-30 35x13 9x27 into play.   24.34-29 24x33 25.39x28 15-20 26.43-38 2-7 27.36-31 8-13 28.48-42 5-10 29.44-39 10-15 30.39-34 20-25 31.38-33? It was necessary to play   31.34-29 19-24 32.29x20 15x24 33.28-23   19-24! 32.31-26 24-29(?) A convincing alternative was   13-19! 33.46-41 9-13 34.34-29 (the only move, since   34.41-37? 24-30 35.35x24 19x39 36.33x44 13-18 37.22x13 11x33 and   34.33-29? 24x33 35.28x39 7-12 36.17x8 3x12 are losing)   13-18! 35.22x13 11x22 36.28x17 19x8 37.29x20 15x24 38.33-28 25-30! and a break through is unavoidable, for example 39.42-38 30-34 40.38-33 24-29 41.33x24 34-39 etc.   33.33x24 13-18 34.22x13 11x33 35.34-29 9x18 36.29x38 3-8 37.38-33? Now Schwarzman simply captures the white outpost on 24. A better defense was   37.24-19 15-20 38.38-33, although it is unsure if a draw was still possible. With the exchange 20-24! 39.19x30 25x34 black gets a very strong outpost on 34 that keeps three white pieces busy.   8-13 38.26-21 7-12 39.42-38 25-30 40.46-41 30x19 41.33-28 6-11 42.41-37 11-17 43.21-16 18-23 44.37-32 15-20 45.50-44 20-24 46.38-33 4-9

Vipulis - Samb 1-1 (2013)
Vipulis - Samb 1-1 (2013)

33.38-32(?) With   33.27-21! 16x27 34.35-30 24x35 35.28-23 19x28 36.33x11 Vipulis could make a break through for only one piece. But black can react with 20-25! (brings the threat 27-31 36x27 18-22 27x20 15x31 into play)   37.39-33 14-19! 38.43-39 19-23! 39.29-24 25-30 40.24-20 15x24 and now that black has won a second piece, he has good chances for making a draw. The game continued with   24-30 34.35x24 19x30 35.43-38 30-35 36.27-21 16x27 37.32x21 14-19 and Samb had no problems to make a draw.

Huseynov - Atse 0-2 (2013)
Huseynov - Atse 0-2 (2013)

Atse from Ivory Coast outplayed his opponent in a classical game 33.27-22 Perhaps the poor exchange   33.31-26 13-18 34.27-21 16x27 35.32x21 23x32 36.38x27 was the best defense for white.   12-18 34.22x11 6x17 35.31-27 17-21! White is in trouble now due to the misplaced piece on 36. 36.43-39? This is already losing. After normal moves the white position will be suffocated, and thus he had to go for   36.28-22?! 2-7 37.33-28 This looks dangerous, but it is enough to make a draw.   21-26 37.48-42 After   37.48-43 2-7 38.39-34 8-12 39.43-39 black has a nice combination with 23-29! 40.34x14 13-19 41.14x23 18x29 42.30x19 26-31 43.33x24 31x42 B+   2-7 38.42-37 4-9 39.39-34 7-12 40.36-31 9-14 41.30-25 16-21! 42.27x16 18-22 43.28x17 12x21 44.16x27 24-29! 45.33x24 19x39 46.35-30 39-44 47.30-24 23-29 48.24x33 44-50 49.33-29 8-12 50.29-24 50-6 51.27-21 26x17 52.32-27 12-18 53.38-32 17-22 54.27-21 13-19 55.24x13 18x9 56.21-16 22-27 57.32x21 9-13 58.31-27 13-19 59.37-32 19-24 60.21-17 6x37

Ano - Shaibakov 2-0 (2013)
Ano - Shaibakov 2-0 (2013)

Ano surprised his opponent with the piece sacrifice 35.27-22! 18x27 36.34-29 23x34 37.39x30 27-31? Shaibakov wants too much. After   12-18 38.28-23 19x39 39.30x10 39-44 40.10-4! 8-13 41.32-28! 27-32 42.28x37 44-50 a draw was the most likely result.   38.43-39! 8-13 39.39-34 12-18? 40.28-22! A second piece sacrifice brings the decision 18x27 41.34-29! and black surrendered.

Getmanski - Budis 2-0 (2013)
Getmanski - Budis 2-0 (2013)

After 6-11 Getmanski finished the game elegantly with the sacrifice 34.26-21!! 27x16 35.37-32 8-13 36.32-27 16-21 37.27x7 12x1 38.34-30! 20-25 39.29x9 25x23 40.9-3 1-6 41.3x26 22-27 42.31x22 18x27 43.40-34 13-18 44.26-31 27-32 45.31x30 32-37 46.36-31 37x26 47.30-13

Buzinskij - Chizhov 1-1 (2013)
Buzinskij - Chizhov 1-1 (2013)

It was very instructive to see how Buzinskij found his way out of this dangerous position. 38.29-24! 19-23 39.24-19! 23-28 40.19x10 15x4 41.32x23 21x41 42.36x47 18x29 White has given up a piece, but in return he is rewarded with a strong defender on 47, and the possibility to make a break through on the black left wing. 43.40-34! 29x40 44.45x34 4-9 Here   12-18 45.30-24 18-23 46.24-20 8-13 47.35-30 7-12 48.30-24 was also insufficient   45.30-24
