Sharafutdinov - Silva 0-2
Sharafutdinov - Silva 0-2

After 34.47-42? the Brasilian player found an elegant way to win the game: 18-22!! 35.49-44 (since   35.43-38 22x33 36.38x20 17-22! followed by   21-27 is hopeless for white)   22x33 36.43-39 13-18 37.39x28 18-22 38.48-43 22x33 39.43-39 24-29! 40.39x28 19-23! 41.28x19 17-22 42.32-28 22x33 43.44-39 33x44 44.40x49 9-13! 45.19x8 3x12 46.42-38 12-18 47.45-40 18-22 48.38-32 21-27 49.32x21 16x36 W+

Tsjizjow - Kychkin 2-0
Tsjizjow - Kychkin 2-0

After 24-30 24.35x24 19x30 25.28x19 14x23 Tsjizjow reacted with the sacrifice 26.27-22! 18x27 27.40-35 11-17(?) 28.35x24 17-22 29.47-41! Now the black position is defenseless against the next white moves. 13-18 30.45-40! 8-13 31.40-35 10-15 32.34-30! 25x34 33.39x30 23-29 or? 34.37-31! 26x39 35.43x12 W+

Baljakin - Bobkow 2-0
Baljakin - Bobkow 2-0

36.39-33! Baljakin ignores the tactical possibility   36.38-33!? Then the threat   47-41 36x47 39-34 47x29 32-28 forces black to play   23-29, but it turns out that 37.35-30 29x49 38.30-25 49x35 39.25x14 13-19 40.14x23 only leads to a draw.   8-12 37.26-21 7-11 38.21-16! 20-25 39.16x7 12x1 40.33-28! Now black is faced with an inflexible formation in the center, and an inactive piece on square 9. 24-29 41.40-34 29x40 42.45x34 9-14 43.38-33 14-20 44.33-29 20-24 45.29x20 25x14 46.43-38 14-20 47.27-21 20-24 48.21-16! It is very instructive how Baljakin manages to suffocate the black pieces. 24-29 (since   1-7 49.34-30 7-12 50.28-22 18x27 51.32x21 is losing too)   49.34-30 18-22 50.28x17 13-18 51.16-11 29-33 52.38x29 23x25 53.11-6 19-23 54.32-27 23-28 55.17-11 18-23 56.11-7 1x12 57.6-1 36-41 58.1x45! 41-46 59.45-50! 28-33 60.50x11 46-10 61.11-33 10-23 62.27-21 23-12 63.21-16 12-7 64.33-38 7-2 65.38-24 W+

Bonadikov - Schwarzman 1-1
Bonadikov - Schwarzman 1-1

It was a bit surprising that Schwarzman failed to win this position against Bonadikov 40.48-43 14-19(?) The most convincing way to win was   22-28! 41.33x22 18x27 42.39-33 13-18! and now for example 43.43-39 (not   43.33-28? 25-30 44.28x10 30x48 B+)   18-22 44.33-29 14-19 45.29x18 22x13 and the lock of the white left wing is decisive.   41.34-29 23x34 42.39x30 25x34 43.33-28 22x33 44.38x40 18-22 45.43-39 19-23 46.39-33 2-8(?) This is perhaps a waste of time. 47.40-34 8-12? And now white forces a draw. 48.33-29! 12-18 49.35-30 21-27 50.32x21 16x27 51.29-24 23-28 52.34-29 13-19 53.24x13 18x9 54.30-24 9-14 55.42-38 26-31 56.37x26 28-33 57.29-23 33x42 58.24-19 14-20 59.15x24 42-47 60.19-13 47x20 61.13-8 20-14 62.8-2 14x46 63.2-13 =

Tolchikov - Nikitsjoek 2-0
Tolchikov - Nikitsjoek 2-0

After 15-20? Tolchikov surprised his opponent with 42.33-29!! 23-28 43.32x23 21x41 44.47x36 19x28 45.35-30! 9-13 46.30-24 White not only wins his piece back, but also has a decisive advantage due to the weakened black left wing. 12-18 47.24x15 13-19 48.34-30 18-22 49.29-24 11-17 50.24x13 28-33 51.39x28 22x33 52.13-8 33-39 53.8-3 16-21 54.3x20 39-44 55.15-10 W+

M.Milsjin - Valneris 0-2
Milsjin - Valneris 0-2

The white player has neglected his right wing, and the next exchange was the fatal mistake 40.34-29? With the sacrifice   40.36-31! 23-28 41.33-29 28-33 42.37-32! 33x24 43.34-29! 24x33 44.38x29 white could still make a draw.   23x34 41.33-28 22x33 42.38x40 20-24! 43.37-32 24-29! 44.32-28 The alternative   44.42-38 11-17 45.40-35 29-34 46.38-33 15-20! 47.32-28 14-19 48.25x23 18x38 quickly loses too.   11-17 45.42-38 14-19 46.40-35 29-34 47.28-22 17x28 48.35-30 19-23 49.30x39 23-29 50.47-42 18-22 and white resigned.
