Round 7 World Cup Ufa

Kudriavcev - Getmanski 0-2
Kudriavcev - Getmanski 0-2

Kudriavcev and Getmanski played a very adventurous game. 33.23-18(?) It was probably better to play   33.34-29 30-34 34.39x30 35x24 35.29x20 15x24 36.44-39 with an interesting position.   22x13 34.31x22 17x28 35.33x22 The white right wing is in a really bad shape now. 3-8 36.38-33 8-12 37.36-31(?) And now the white left wing becomes vulnerable too. 14-19! 38.37-32 12-17! 39.32-28 16-21! 40.33-29 9-14 41.29-23 21-27 42.26-21 27x29 43.21x12 11-16 Here   29-33! was a much more efficient way to win the game.   44.34x23 6-11 45.25x34 11-17 46.12x21 16x36 47.39-33 36-41 48.23-18 13x22 49.28x17 41-47 50.33-28 47-20 51.17-11 19-24? It is not clear what Getmanski had in mind with this move. Here black could still win with   20-25! 52.34-29 14-20!! 53.11-7 19-24 54.28-23 24x33   52.11-7! 14-19 53.7-1 20-14 54.34-30 14-3 55.28-22 3-26 56.1-34 26-3 57.34-1 4-9 58.1-34 9-14 59.34-48 3-26 60.22-18 24-29 61.18-13 35x24 62.48-34 19x8 and now the white player made a painful mistake with 63.34x25?? which gave black the opportunity to catch the white king with 26-3! B+.

Valneris - Dusseldorp 1-1
Valneris - Dusseldorp 1-1

Valneris has outplayed his opponent, and here he could for example win using 43.34-29 11-17 44.38-33 17-22 45.28x17 21x12 46.33-28! etc. But the plan he chooses in the game also looks OK.   43.24-20 11-17 44.20x9 13x4 45.38-33 17-22 46.28x17 21x12 47.43-38 18-23 48.33-28 19-24 49.28x19 24x13 50.38-33 4-10! The only move for black. 51.15x4 26-31 52.4x1 31x42 White has two pieces advantage, yet it is a difficult endgame. 53.27-22 42-47 54.34-29(?) It seems safer to play   54.1-29! here.   16-21! 55.22-18(?) The problem for white is that after the backwards exchange   55.44-40 35x44 56.39x50 47-42! there is no easy way to get his pieces safe.   47-42! 56.18-13 35-40!! 57.44x24 42-48 58.24-20 48x4 59.20-15 21-26 and van Dusseldorp had completed his miraculous escape.

Tsjizjow - Ndjofang 2-0
Tsjizjow - Ndjofang 2-0

In this 'classical' position Ndjofang has a disadvantage due to the inactive piece on 6. 21-26 43.43-38 11-17 44.38-33 6-11 45.47-41 4-9 46.41-36 9-14(?) 47.34-30! 23-29 48.37-31 26x37 49.32x41 29x38 50.28-23 19x28 51.30x10 38-42? Here black needed to play   28-33 52.39x28 38-43 to make a draw.   52.27-21! 16x27 53.41-37 42x31 54.10-5! Suddenly the black position is completely lost. 28-33 55.39x28 13-19 56.5x23 31-37 57.23-19! Normally a position like this is a draw, but Tsjizjow has looked further. 37-42 58.19-8! 42-48 59.8x38 48-34 60.38-27 34-12 61.35-30 12-17 62.28-23 17-12 63.23-19 12-8 64.27-13 W+

Mukhametov - Baljakin 0-2
Mukhametov - Baljakin 0-2

There is nothing wrong with 21-26!, but it is safe to assume that Baljakin would rather have won using   21-27! 40.31x11 12-17 41.11x22 24-30 42.35x24 13-18 43.22x13 8x48!   40.31-27 13-18 41.27-21 26-31 42.21-16 2-7 43.42-37 31x42 44.38x47 B+

Ishmuratov - Schwarzman 0-2
Ishmuratov - Schwarzman 0-2

After 35.44-39? Schwarzman gained a decisive advantage using 18-23! Now black threatens to take the combination   24-30 25x34 23-29 34x23 19x46 and white cannot neutralize this threat with   36.41-37? due to 24-30 37.25x34 23-29 38.34x23 19x28 39.32x23 7-11 40.6x17 12x41B+ Therefore he had to play   36.39-33 23-29! 37.43-38 29-34! and the strong outpost on 34 was decisive: 38.27-22 24-30 39.32-28 8-13 40.22-17 12x21 41.26x17 7-12 42.17x8 13x2 43.28-22 30-35 44.41-37 19-24 45.38-32 35-40 46.32-27 40-44 47.37-31 24-30 B+

Ldokow - Georgiev 0-2
Ldokow - Georgiev 0-2

Another very spectacular game! The locked formation on the left side of the board is highly unusual. 26.30-25(?) 7-11 27.24-20 10-14? Here black could win a piece using   13-19! 28.20-14 (note that   28.29-24? 19x30 29.35x24 does not work after 8-13! 30.33-29 10-15 31.39-33 13-19 32.24x13 15x24 33.29x20 23-28 34.32x23 18x40 B+)   9x20 29.25x14 10-15 30.32-28 19x10 31.28x19 4-9 etc.   28.29-24 23-28 29.32x23 18x40 30.35x44 5-10 31.20-15 14-19 32.44-40 19x30 33.25x34 10-14 34.40-35 13-19 35.35-30? White needed to create space using   35.34-30 followed by   36.39-34. Now Georgiev forced a win using   19-23! 36.33-29 23-28! and white sacrificed a piece, since 37.38-33? is followed by the lethal 27-32! B+   37.36-31 27x36 38.38-32 21-27 and white resigned.

Fedin - Amrilloew 1-1
Fedin - Amrilloew 1-1

In this tricky endgame Amrilloew spoiled the victory with 49-27? 70.20-14! 27-4 71.19-24! 33-39 72.24-15 4-13 73.15-47! = Black should have played   33-38! 70.19-41 50-22 71.20-14 22-4 72.41-47 38-43 73.47-15 43-48 74.14-10 49-32 75.10-5 32-46 76.15-47 4-36 77.47-15 35-40 78.15-29 48-34 79.29-38 40-45 and according to the computer black can win, although it is not immediately clear how. So I will leave this as an exercise to the reader :-)

M.Milsjin - W.Milsjin 0-2
Milsjin - Milsjin 0-2

After junior's 28.45-40? Milsjin senior forced a winning advantage using 20-25! 29.29x20 15x24 30.40-34 17-22! 31.28x6 24-30 32.35x24 19x28 33.32x23 18x29 and black had no problem to break through the weakened white right wing: 34.49-44 25-30 35.31-27 30-35 36.27-22 29-34 37.37-31 26x37 38.42x31 34-40 39.44-39 40-45 40.38-33 35-40 41.31-26 12-18 42.22-17 45-50 43.17-11 40-44 44.11-7 1x12 45.6-1 50-45 46.39x50 12-17 B+
