Mejia - Getmanski 0-2

Getmanski paved the way for a victory with a strong Ghestem attack. 23-29! 33.44-40 7-11 34.39-33? White should have played 34.39-34 18-23 35.42-37 8-12 36.48-43 An important difference with the game is that white has the possibility to play 37-31. 18-23! 35.28-22 8-12 Here 36.36-31 12-17! 37.33-28 21-26 38.42-37 17-21 39.48-42 11-17 40.22x11 6x17 41.27-22 21-27 42.32x12 23x41 was also losing for white. 36.48-43 12-18 37.43-39 21-26 38.42-37 11-17 39.22x11 16x7 40.33-28 7-12 41.28-22 6-11 42.38-33 29x38 43.32x43 12-17 44.43-38 17x28 45.27-21 26x17 46.40-34 10-15 47.36-31 24-29 48.38-32 29x40 49.35x44 15-20 50.39-34 28-33 51.44-39 33x44 52.34-29 23x34 53.30x50 18-22 54.32-27 13-18 55.37-32

Shaibakov - Lognon 2-0

Shaibakov had launched a promising attack through the center. However, in such positions a draw is usually still possible for the defending player. 20-24 48.39-33 2-8 Also 2-7 was possible, and now for example 49.31-27 7-11 50.34-29 25-30! 51.29x20 30-34 52.20-15 34-40 53.44-39 40-45 49.31-27 12-17! And certainly not 8-13? 50.27-22! and the game is over. 50.34-29 8-12? Here Lognon needed to play 25-30! 51.29x20 30-34 52.20-15 34-40 53.44-39 40-45 to make a draw. 51.29x20 25x14 52.33-29 14-20 53.27-21! With an elegant move Shaibakov finishes the game. 17-22 54.23-19! 26x17 55.19-13 22-28 56.13-9 17-21 57.9-4 12-17 58.4-18 21-26 59.18-27 20-25 60.27-49

Ano - Boomstra 1-1

Ano was in big troubles against Boomstra. 14-20! This introduces the threat 18-23 28x8 17x28 32x23 4-9 8x17 11x33 41.48-42? White should have ignored the threat and play 41.34-30! Then after 18-23 42.28x8 17x28 43.32x23 20-25 ( 4-9 44.8x17 11x33 45.48-43! is also insufficient) 44.8x17 11x33 45.30-24 33-39 46.26-21! white has enough compensation for the lost piece. 3-8 42.50-44 20-25? After 20-24! 43.44-40 4-9 44.40-35 9-14 45.38-33 14-20 46.42-38 20-25 47.34-29 15-20 Boomstra would probably have won the game. 43.34-29? 15-20? And here 25-30! 44.44-40 30-34 45.29-24 34x45 46.24-19 13x24 47.22x2 45-50 48.2x30 50x36 would have resulted in an extremely difficult endgame for black. Note that 49.30-34? is not possible due to 17-21 50.34x27 36x22 B+ 44.26-21! Ano grabs his chance to get out of the locked position. 17x26 45.37-31 26x48 46.44-39 48x23 47.28x19 13x24 48.22x2 24-29 49.2x16 29-34 50.32-28 34-40 51.28-22 40-44 52.22-17 12x43 53.16x35 4-10 54.35-19 6-11 55.19x5 25-30 56.5-28 11-16 57.28-46 30-34 58.46-5 34-40 59.5-46 40-45 60.46-5 20-25 61.5-46 25-30 62.46-5 30-34 63.5-46 34-39 64.46-5 39-43 65.5-46 43-49 66.46-5 45-50 67.5-46
