Round 7

Vilcinska - Overes 0-2
Vilcinska - Overes 0-2 (2011)

In an adventurous game Overes increased the pressure on the white position with 12-17! Now 27.39-33? 18-22! is very bad for white, for example 28.37-31 10-15 29.31-26 24-29 30.33x24 22x42 31.48x37 27x38 32.43x32 20x29 and the material advantage for black should be decisive, despite the vulnerable black right wing.   27.38-33? White doesn't find a solution for the problems. The best defense was   27.39-34! 18-22 28.38-33! 27x29 29.37-32 22x33 30.32-27 21x32 31.43-38 32x43 32.48x28 23x32 33.34x23 19x28 34.30x8 and black should probably go for a draw with 9-13 35.8x19 14x23 36.25x5 4-9 37.40-34 9-14 38.5x19 23x14 .   27x29 28.39-34 23x32 29.34x12 17x8 30.37x28 13-18 31.36-31 11-17 32.43-38 9-13 33.48-42 18-22 34.38-33 21-26 35.42-37 13-18 36.41-36 18-23 37.40-34 23x41 38.36x47 26x37 39.34-29 10-15 40.29-23 19x39 41.30x10 4-9 42.25x21 15x4 43.45-40 16x27 44.40-34 39x30 45.35x24 27-31 46.24-19 4-9 47.49-43 31-36 B+

Fedorovich - Doumesh 2-0
Fedorovich - Doumesh 2-0 (2011)

Fedorovich has some advantage in this position, and this results in an impressive victory. 39.42-38! 14-20 40.39-34! 19-23(?) Obviously   20-24? was not possible, but   19-24! was a serious alternative. After 41.28-23 black can successfully defend the position with 18-22! 42.43-39 11-16 43.40-35 21-27! 44.37-31 20-25 45.29x20 15x24! etc. But it must be noted that this line is not without danger for black, since any deviation from it can lead to a quick loss.   41.28x19 13x24 42.29-23! 18x29 43.34x23 White penetrates the black center. Now the formation 15/20/24 has become useless, and black needs to find a way to develop these pieces. 11-17? This move is probably losing. It was better to play   11-16 44.23-18 24-30 45.43-39 30-35 46.37-32 35x44 47.39x50, although white keeps a substantial advantage.   44.23-18 21-26 45.43-39! 24-30 46.40-35! 20-24 47.33-28 White has paralyzed the black left wing. 15-20 48.28-23 20-25 49.38-32 17-21 50.18-12! An elegant sacrifice to finish the game. 8x17 51.23-18 24-29 52.35x33 25-30 53.33-29 W+

Motrichko - Sadowska 2-0
Motrichko - Sadowska 2-0 (2011)

Sadowska is in a lot of trouble because of the inactive piece on 6. 38.39-34? With   38.33-28! Motrichko could already force a winning advantage. The main reason for this is that after the logical reply 24-29 white plays 39.39-33!! and 20-24? fails due to 40.28-23 29x18 41.27-22 17x39 42.26x17 12x21 43.38-33 39x28 44.32x3 W+   12-18 39.33-28 8-13 40.27-22! Here   40.34-30? is not a good idea due to 13-19! etc., and after   40.37-31 black can easily make a draw with 17-22 41.28x17 21x12 42.27-21 16x27 43.31x22 18x27 44.32x21 13-18 etc.   18x27 41.37-31 17-22 42.28x17 21x12 43.31x22 Just like in the previous game the black player is faced with a powerless formation 15/20/24. In the game she does not find a solution for this problem. 6-11 44.32-28 20-25 45.36-31 11-17 46.22x11 16x7 47.28-22 7-11 48.38-33 The inactive piece on 15 is now the main theme of the position. With 12-18! 49.31-27 13-19 50.22x13 19x8 51.33-28 8-12! black could defend the position.   12-17? 49.33-28! But now the exchange 11-16 50.22x11 16x7 is hopeless for black after 51.26-21!   25-30 50.34x25 24-29 51.35-30 29-33 52.28x39 17x28 53.30-24 13-18 54.25-20 11-17 55.20-14 28-32 56.31-27 32x21 57.14-9 21-27 58.9-4 17-22 59.24-19 W+

Balthazi - Yuldasheva 1-1
Balthazi - Yuldasheva 1-1 (2011)

Black has some weaknesses due to an uneven piece distribution. It is instructive how Balthazi takes advantage of that. 17-21 40.31-27 11-17 41.43-39 21-26? Yuldasheva plays too passively. For example   17-22 would have given much better opportunities to defend the position.   42.39-34 17-22 43.34-29 22x31 44.36x27 6-11 45.32-28 11-17 46.37-32 17-22 47.28x17 12x21 48.29-24 8-12 49.30-25? This gives black an escape route to a draw. White should have played the moves in a slightly different order to eliminate this possibility:   49.33-28! 12-17 50.38-33! 17-22 51.28x17 21x12 52.42-37! 12-17 53.33-28 17-21 54.30-25 14-19 55.28-23! 18x20 56.25x23 W+   12-17 50.33-28 17-22 51.28x17 21x12 52.32-28 12-17 53.42-37 At first sight everything looks alright for white. But black can force a break-through using a well known piece sacrifice: 16-21! 54.27x16 18-22 55.28-23 22-27 56.35-30 27-31 57.23-19 31x33 58.19x8 33-38 59.8-2 15-20 60.24x15 38-43 61.2-13 17-21 62.16x27 43-49 63.13-18 49x21 64.18-45 21-3 65.45-23 3-8 66.23x5 8x35 67.15-10 35-2 68.10-4 2-35 69.25-20 35-2 70.5-46 2-16 71.46-37 16-49 72.20-14 49-35 73.4-27 26-31 74.27x36 35-2 75.37-23 2-16 76.14-9 16-2 77.36-27 2-11 78.9-3 11-6 79.3-12 6-39 80.27-16 39-22 81.12-1 22-17 82.1-6 17-3 83.6-39 3-8 84.16-2 8-26 85.39-48 26-17 86.48-34 17-33 87.34-45 33-38 88.45-50 38-42 =

Round 8

Nogovitsyna - Motrichko 2-0
Nogovitsyna - Motrichko 2-0 (2011)

In this crucial game between the numbers 1 and 2 in the ranking, Motrichko is under pressure due to a 6 tempi disadvantage. 20-24 44.29x20 25x14 And after this backwards exchange the tempi difference has grown to +8 for white. 45.43-38 14-20 46.34-29 11-17 47.22x11 16x7 48.38-33 4-9 49.30-25 9-14 50.28-22 The position is still a draw, but black must be careful. 19-24(?) Almost any other move was less dangerous, for example   7-12 51.33-28 21-26 52.29-23 8-13 = or   8-12 51.33-28 21-26 52.36-31 26x37 53.32x41 19-24! =.   51.32-28 21-26 52.22-17 8-13? It looks completely over, but black could still make a draw by the paradoxical   7-12?! 53.17-11 8-13! 54.11-6 14-19! 55.25x23 13-18 56.29x20 18x38 etc.   53.28-23! 13-19 54.23-18 19-23 55.17-12 23x34 56.12x1 24-29 57.33x15 34-39 58.1-6 39-43 59.6-28 43-49 60.28x5 W+

Round 9

Vilcinska - Doumesh 0-2
Vilcinska - Doumesh 0-2 (2011)

It seemed like Vilcinska had found a clever defense in this difficult position with 45.34-30!? The idea behind it is 20-25 46.29x20 15x24 47.37-31! 25x34 48.31-26 and on the next move white forces a break-through with   49.28-22. But Doumesh simply played   21-26! 46.30-25 26-31! and won the game after 47.25x23 31x42 48.29x20 18x38 49.32x43 15x24 50.45-40 42-47 51.40-34 47-36 52.28-22 17x28 53.34-30 36x9 54.30x19 28-32 55.35-30 32-37 56.30-25 9-4 In the position of the diagram, white should have taken the combination   45.28-23! 19x30 46.29-23 18x29 47.27-22 17x28 48.32x14 to make a draw.

Tkachenko - Nogovitsyna 0-2
Tkachenko - Nogovitsyna 0-2 (2011)

The reigning world champion Tkachenko is playing a difficult tournament. In this classical position she is under pressure due to the over-development of the white pieces, and due to the strong black defensive pieces on squares 2 and 4. She chooses the wrong plan, and this results in a heavy loss. 39.38-33 17-21 40.43-39(?) White needs to look for expansion somewhere. Here   40.27-22 12-17 41.22x11 16x7 42.32-27 21x32 43.28x37 7-12 44.34-30 12-17 45.37-32! was a possibility to break the classical structure.   12-17! 41.48-42 2-8 42.42-38? Here   42.42-37 8-13 43.27-22 4-10 44.22x11 16x7 45.37-31 was needed.   8-12! 43.34-30 23-29! Nogovitsyna finds a winning plan. After 44.27-22(?) 21-26! 45.22x11 16x7 white can not play 46.32-27 due to 29-34 B+   44.39-34 29x40 45.35x44 24x35 46.33-29 12-18 47.29-24 19x30 48.25x34 14-19 49.34-29 4-10 50.44-39 10-15 51.39-34 15-20 52.27-22 18x27 53.29-23 17-22 54.23x25 22x42 B+

Makarenkova - Overes 1-1
Makarenkova - Overes 1-1 (2011)

24-30? 43.40-34! 30-35 44.38-33? Makarenkova started right, but now she missed the winning combination   44.34-29! 23x34 45.39x30 35x24 46.32x23 18x29 47.38-33 29x49 48.47-42 49x21 49.26x10 W+   12-17(?) Here   14-20! 45.33x22 11-17 46.22x11 16x7 47.39-33 20-24 was a better continuation.   45.33x22 17x28 46.43-38 14-20 47.47-41 20-24 48.38-33 11-17! Overes sacrifices a piece to make a draw. 49.33x11 16x7 50.39-33 13-19 51.27-21 24-30 52.34x25 35-40 53.21-17 40-44 54.33-29 23x34 55.17-12 19-23 56.12x1 23-29 57.1x23 29x18 58.25-20 44-49 =

Tansykkuzhina - Fedorovich 2-0
Tansykkuzhina - Fedorovich 2-0 (2011)

At first sight it seems that the white strategy has not been very successful. But Tansykkuzhina finds a very clever way to create problems for her opponent. 40.26-21! Based on 11-16 41.39-33! 28x30 42.38-33 16x27 43.33-29 24x33 44.35x4, although black can make a draw after 33-39 45.42-38 22-28 46.4x31 28-33 47.38x29 39-43.   7-12 41.42-37! And now 11-16? even loses due to 42.38-33 16x27 43.34-29!! W+   19-23 42.38-33 14-19 43.21-16 11-17 44.37-31! It came out of nowhere, but now black is in extreme danger. 9-14? Here black should have sacrificed a piece with   22-27! 45.31x11 9-14 46.33x22 23-29 47.34x23 19x6 48.39-33 14-19 and black has enough compensation for a draw.   45.31-27 22x31 46.33x11 31-37 47.11-6 37-42 48.39-33? Analytically this is not the strongest move, but again it creates the maximum amount of problems for the black player. 14-20? With   23-29! 49.34x23 19x39 50.6-1 42-47 51.1x9 39-43 black could make a draw, but one can easily understand that black did not trust this endgame.   49.6-1 12-17 50.1x29 42-48 51.35-30? 24x35 52.29x15 48x25 53.15-10 19-24? Here black could still make a draw with   25-14.   54.10-28 17-21 55.16x27 35-40 56.28-14! 25x31 57.36x27 24-30 58.27-21 30-34 59.21-16 and black resigned because of 40-45 60.16-11 34-40 61.11-6 40-44 62.50x39 45-50 63.6-1 W+
