Seaport Masters 2012 round 3

In an already lost position Kroesbergen played 4-9? Now Borghetti could have decided the game immediately using 44.37-31 26x37 45.25-20 14x25 46.48-42 37x48 47.33-28 48x19 48.23x3 W+ But also after the exchange ≡ 44.37-32 27x38 45.33x42 his advantage was big enough to win the game. 26-31 46.42-37 31x42 47.48x37 11-17 48.39-34 17-21 49.47-41! 36x47 50.23-19 14x23 51.34-30 23x34 52.30x39 47x20 53.25x3 12-17 54.3-14 18-22 55.14-32

Zhou tried to attack the black piece on 24, but he underestimated the tactical possibilities of black. 35.39-34? It was better to play the neutral move ≡ 35.41-36. ≡ 22-27! (prevents 36.34-29? with 12-18 37.29x20 19-24 38.20x29 27-32 39.38x27 21x45 B+) ≡ 36.37-32 13-18 37.34-29? (here ≡ 37.42-37 was necessary) and Shaibakov finished the game with ≡ 18-23!! 38.29x20 21-26 39.32x21 23x32! 40.38x27 19-24 41.20x29 17-22 42.27x18 12x45 43.21-17 16-21 44.33-29 21x12 45.29-24 45-50

When Golubeva played 30-35? Mbongo replied with the brilliant sacrifice 43.23-18!! 12x23 44.28x19 13x24 45.22-17! 35x44 46.39x50 Now black is in serious trouble. It is only a matter of time before white makes a break through, while the black counter attack is severely hampered by the strong defending piece on 50. 8-13 47.33-28 25-30? 48.28-23 30-34 49.27-22 24-29 50.23-18 34-39 51.18x9 29-33 52.38x29 39-43 53.50-45! To prevent black from making a king with 43-49? 54.9-3! W+. ≡ 20-25 54.9-3 43-49 55.32-28 49-35? 56.22-18 35-19(?) Now that he has the victory within reach ( 57.3-14 19x46 58.14-5 W+) Mbongo makes a terrible mistake. ≡ 57.29-23?? 16-21! 58.23x14 21x41 and the game ended in a draw after 59.3-17 41-46 60.14-9 46-14
