Seaport Masters 2012 round 11

Kroesbergen - Schwarzman 2-0
Kroesbergen - Schwarzman 2-0 (2012)

In this uncomfortable position Kroesbergen decided to burn all ships behind him and go for a confrontation. 22.39-34! 18-22 23.27x18 13x22 24.43-39!? 12-17 25.48-43 14-19! 26.31-27 22x31 27.36x27 19-23! Schwarzman reacts with an original piece sacrifice. 28.29x18 17-22 29.35-30!? A spectacular reply from Kroesbergen. However,   29.18-13 9x18 30.27-21 16x27 31.32x21 26x17 32.34-30 25x34 33.39x19 was more realistic here.   22x31 (after   24x35? white can play 30.18-13 8x19 [not   9x18? due to 31.33-29 22x31 32.29-24 20x29 33.34x1 W+]   31.27x18 3-8 32.32-27! and black cannot threaten the white outpost)   30.30x19 31-36 31.32-27! A truly unique position has emerged on the board. The two white outposts look very vulnerable, but it is far from straightforward for black to take advantage of it. 7-12 32.18x7 11x2 33.34-30 25x34 34.40x29 It may be considered a success for white that he managed to defend the material advantage. Schwarzman will have to invest a second piece in order to make a break through. Even though the position is clearly better for black, the game is by no means over yet. 20-25 35.44-40 26-31 36.37x26 36-41 37.38-32 2-7 38.39-34 41-47?? An unprecedented black out from Schwarzman. He did not even await the white response 39.43-39 47x38 40.33x42 , and resigned immediately.

Thijssen - Mbongo 2-0
Thijssen - Mbongo 2-0 (2012)

When Mbongo played 6-11? Thijssen replied with a strong Ghestem attack 40.28-22! 18-23 41.47-42! 9-14? It was necessary to play   2-8 42.42-38 8-12 43.33-28(!) It is crucial that 9-14? now fails due to the combination 44.34-29! 24x31 45.30-24 19x30 46.28x6 W+   12-18 44.38-33 9-14 45.30-25 11-17 46.22x11 16x7 47.27x16 18-22 48.28x17 24-29 49.33x24 19x39 and black can still fight for a draw.   42.33-28! 24-29!? Due to the earlier mentioned combination   2-8 43.42-38! 8-12? 44.34-29! etc. black had no other choice.   43.30-24! 19x39 44.28x10 The problem for black is now that he cannot advance with his front piece due to 39-44? 45.37-31! 26x17 46.10-4 21x32 47.4x26. Because of this he will lose material.   29-34 45.10-4 13-19 46.4-10 19-24 47.10-28(?) Here   47.42-38! was more convincing.   39-43 48.28-39 34-40? 49.39x48 40-45 50.48-34 45-50 or? 51.34-48! and without awaiting 50x17 52.37-31 26x28 53.48-43 21x32 54.43x30 black resigned.

NDiaye - Borghetti 2-0
NDiaye - Borghetti 2-0 (2012)

Just like in his game against Golubeva, Borghetti is under pressure due to a huge tempo difference. 8-12? This is a dangerous move, although it is not fatal yet. 41.17x8 13x2 42.21-17! The white outpost is very strong, since it keeps two black pieces busy. 2-7? This is already losing. 43.38-33 4-9 44.40-34? But here white needed to be more active with   44.33-29! 9-13 45.43-39! The idea behind these moves is to prevent the exchange 7-12? 46.17x8 13x2 with the small but charming combination 47.29-23 19x28 48.39-33 28x39 49.40-34 39x30 50.35x15 W+   9-13 45.34-30 20-24 46.43-39 NDiaye has chosen another way to prevent the exchange of the strong piece on 17. If black plays 7-12? 47.17x8 13x2 now, white can simply win the piece on 24. But black has a better defense:   13-18! Now 47.17-12? fails due to 24-29! 48.33x22 7x27 with a draw.   47.39-34 18-23? This is wrong. With   7-11! 48.34-29 11x22 49.29x20 19-23 50.20-15 23-28 51.33-29 28-32 52.15-10 22-27! black could have escaped.   48.30-25! 7-11 49.17-12 11-17 50.12x21 6-11 51.34-30 and black resigned.

Zhou - Georgiev 0-2
Zhou - Georgiev 0-2 (2012)

Zhou had played well against the world champion. But after 37.33-28 22x33 38.38x29 19-23! 39.30-25 23x34 40.44-39? he became the victim of a beautiful tactical trap that Georgiev set up for him. 34-40! 41.45x34 10-15!! All of a sudden the white position is lost. The black threat 14-20 25x14 13-19 14x23 18x40 cannot be neutralized by   42.34-29? because of 26-31! 43.36x27 18-22 44.27x20 15x44 45.43-39 44x33 46.42-38 33x42 47.47x38 12-18 with a double opposition. And after   42.34-30? 15-20! white will lose the piece on 30, since 43.39-34? is prevented by 14-19 44.25x23 18x40 B+ Therefore Zhou sacrificed a piece with   42.43-38 14-20 43.25x14 13-19 44.14x23 18x40 45.39-34 40x29 46.38-33 29x38 47.42x33 and lost the game after 15-20 48.33-29 20-25
