Round 10

Fedorovich - Makarenkova 1-1
Fedorovich - Makarenkova 1-1 (2011)

After 37.27-22? Makarenkova made a draw with 17-21! 38.26x17 12x21 39.31-26 13-18! 40.22x2 21-27 41.32x21 23x45 42.21-17 29x38 43.35-30 24x35 44.2x47 16-21 45.17-12 45-50 46.26x17 50x11 47.12-8 11-2 48.25-20 2x46 49.20x9 35-40 50.47-33 40-45 51.33-50 46-14 52.9x20 15x24 53.50-28 24-29 54.28-46 45-50 = The backwards exchange   37.40-34! 29x40 38.35x44 would have given good opportunities to white, for example 6-11 39.27-22! 15-20 40.44-40 12-18 41.26-21! 16x36 42.40-35 18x27 43.32x3 23x34 with a difficult position for black.

Overes - Motrichko 1-1
Overes - Motrichko 1-1 (2011)

After 39.38-33(?) 21-27 40.44-39 20-25 Motrichko could have played the unorthodox move   19-24! in an attempt to suffocate the white position. But it is not sure this would be enough to win the game, for example 41.48-43 2-7 42.43-38 7-11 43.41-37 11-16 44.37-32 5-10 45.32x21 26x17 (this is better than taking forward) 46.36-31! 12-18 47.23x21 16x36 48.28-22 and the game will end in a draw.   41.48-43 15-20 42.34-30 25x34 43.29x40 5-10 44.43-38 2-7 45.41-37 7-11 46.40-35? 10-15? But here   20-24! was certainly winning, for example 47.39-34 10-15 48.34-30 11-16 49.30-25 15-20 50.37-32 26-31 51.32x21 16x27 B+   47.33-29 11-16 48.38-33 16-21 49.37-32 27x38 50.33x42 12-17? 51.23-18! 21-27 52.35-30? And now Overes misses a winning move:   52.39-34! (prevents 19-24? with 53.36-31 24x13 54.31x11 W+)   20-25 53.35-30 15-20 54.28-23! 19x28 55.18-13 27-32 56.13-8! 17-22 57.42-37 32x41 58.36x47 28-32 59.8-2 etc.   17-22 53.28x17 27-31 54.36x27 19-23 55.17-11 23x43 56.11-6 43-48 57.42-38 48x25 58.6-1 25-30 59.1-6

Round 11

Tansykkuzhina - Doumesh 2-0
Tansykkuzhina - Doumesh 2-0 (2011)

Doumesh was under pressure here, and she chose the wrong plan. 9-14(?) This is still OK for black, but   18-22 55.28x17 21x12 56.32-28 9-14 was safer.   55.28-22! 19-23 56.22x13 23x34 57.13-8 34-40? After this logical move Tansykkuzhina wins beautifully. Here   14-19 58.8-2 19-23 59.27-22 34-40 was the correct defense for black.   58.8-3! 14-19 59.3-8 19-23 60.8-12! 40-45 (since after   23-28 61.12x45 28-33 white can choose how to win)   61.12x29! 45-50 62.37-31! 26x28 63.29-15 and Doumesh did not await 21x32 64.43-39 50x33 65.15x27 28-33 66.27-43 W+

Motrichko - Fedorovich 0-2
Motrichko - Fedorovich 0-2 (2011)

In this interesting classical position white's position would not be less after 36.38-33! 6-11 (after   17-21 white can play 37.28-22! 12-17 38.22x11 6x17 39.48-43 24-29 40.33x24 19x30 41.34x25 23-28 42.32x12 21x41 43.36x47 26x37 44.12x21 16x27 45.25-20 3-9 46.39-34! 27-31 47.40-35 31-36 48.20-14 9x20 49.47-42 37x30 50.35x15 with a draw)   37.40-35 etc. But with   36.27-22? Motrichko dug her own grave: 18x27 37.31x11 6x17 38.38-33? Here   38.48-42 was a better defense for white. Note that   36-31? was also losing after 12-18! 31-27 16-21! 27x16 18-22 B+   12-18! This simple move prevents the intended 39.48-43? due to 23-29 40.34x21 16x49 B+, and it also brings the positional threat   18-22 into play. Therefore Motrichko sacrified a piece, and subsequently lost the game.   39.37-31 26x37 40.32x41 23x32 41.48-42 3-9 42.42-37 9-14 43.37x28 18-23 44.40-35 23x32 45.34-29 14-20 46.29-23 19x28 47.33x11 16x7 48.41-37 32x41 49.36x47 13-18 50.45-40 20-25 51.40-34 18-23 52.39-33 8-13 53.47-42 13-18 54.42-38 18-22 55.38-32 7-11 56.34-29 23x34 57.32-28 11-17 58.28-23 17-21 59.33-29 24x33 60.23-19 33-38 61.19-13 38-43 62.13-8 43-49

Tkachenko - Overes 2-0
Tkachenko - Overes 2-0 (2011)

After 4-10? Tkachenko climbed her way up in the ranking with the combination 33.33-28 22x33 34.34-30 25x34 35.23-19 14x23 36.43-39 W+

Yuldasheva - Nogovitsyna 0-2
Yuldasheva - Nogovitsyna 0-2 (2011)

Nogovitsyna had an easy day after 18.50-45? 24-30! 19.35x22 21-26 20.28x19 26x30 21.38-33 17x39 22.43x25 14x23 and with a piece more black easily won the game.

Turiy - Sadowska 1-1
Turiy - Sadowska 1-1 (2011)

After 22.47-42? Sadowska could have followed the example of the two previous games by taking the combination 24-30! 23.35x22 23-29 24.33x24 14-19 25.24x13 9x47 B+. But she played   8-13? and the game ended in a draw.

Round 12

Tansykkuzhina - Makarenkova 2-0
Tansykkuzhina - Makarenkova 2-0 (2011)

Tansykkuzhina has a superior position, and is a bit unlucky that the position is still a draw. 21-27 52.28-22 27x18 53.23x12 13-18! 54.12x23 9-13 55.25-20 14x25 56.23-19 13-18 57.19-14 18-22 58.14-9 22-27 59.9-3 27-32 60.3-9! This prevents both 32-38? 61.9-27! 38-42 62.27-38 42x33 63.29x38 W+ and   32-37? 61.9-14 37-42 62.14-37 42x31 63.36x27 W+ Therefore black had to sacrifice a piece with   25-30 61.24x35 32-38 62.9-25 38-42 63.29-24 As Frank Verdel noted, with   63.25-14! white could force black to give another piece, since 42-47? is prevented due to 64.14-46 47x20 65.36-31 26x37 66.46x25 W+. But it turns out that   15-20! 64.14x25 42-48! is still a draw, for example 65.25-14 48-42 66.29-23 42-38 etc.   42-48 64.24-19! The black king is in an awkward position, which gives white the opportunity to make a second king. 48-42 65.25-43 15-20 66.19-13 20-24 67.13-9 42-48(?) 68.43-32 48-39? 69.9-3? 39-11 70.32-49 11-16 71.3-25 16-7 72.25-48 7-2 73.49-38 26-31? 74.38x15 W+ With   2-19! 74.38x20 black could have made a standard draw. The white piece on 35 is too far advanced. Only when it is on the diagonal 6/50 white can chase the black king from the main diagonal:

Because of the threat   36-31 26x37 49-32 37x39 black has only one safe place on the main diagonal, namely square 5. But after   19-5? white simply waits a move with 49-43 and the black king has nowhere to go. So black must leave the main diagonal, and this gives white the opportunity to make a third king. Then white can for example build the capture position below, in which the black king is always caught within a couple of moves.

Round 13

Yuldasheva - Overes 1-1
Yuldasheva - Overes 1-1 (2011)

In a spectacular game in which Yuldasheva placed an outpost on 18, Overes missed the winning combination 7-11! 30.18x7 21-27 31.32x21 16x27 32.7x16 26-31 33.37x26 27-32 34.38x27 24-30 35.35x24 20x40 B+ and played   21-27 instead.
