11-17!

This is the start of a brilliant long term plan ending in diagram 2. The best reaction for white is now to play 29.39-34! Then the standard reaction 24-29 30.33x24 17-22 31.28x17 23-28 32.32x23 21x43 (  18x40? 35x44 21x41 is even worse for black after 36-31! 12x21 47x36 26x37 42x31)   48x39 18x20 34-29 12x21 30-24 19x30 35x15 results in a satisfactory position for white. But Getmanski has estimated well that the white player does not trust these complications.

  29.27-22 18x27 30.37-31 26x37 31.42x11 6x17 32.36-31 12-18 33.31-27 23-29!?

Black plays a strong Ghestem attack. Now white can take a simple combination using 34.28-22! 17x37 35.39-34 21x43 36.34x3 with a huge advantage. As it is unlikely that both players have missed this opportunity, probably black has played 32... 13-18 instead of 12-18.

  34.47-42 18-23 35.50-45 8-12 36.39-34 29x40 37.45x34 12-18 38.42-37 4-9!

Without the pieces on 5 and 48 this is a well known position. Then the position is lost for black:   43.27-22 18x27 44.34-29 23x34 45.30x39 27-31 46.37x26 17-22 47.26x17 22x11 48.32-27 11-17 49.27-22! etc. But with these extra pieces it turns out that it is not white but black who wins the game.

  39.27-22 18x27 40.34-29 23x34 41.30x39 27-31 42.37x26 5-10!

White can not keep the combination   13-18? 28-23 19x37 38-32 37x28 33x15 into play.

  43.48-42 13-18 44.42-37 9-13 45.39-34 18-23! 46.37-31 10-15 47.31-27 13-18

Since white is out of moves after 48.34-30 15-20 he decides to escape into an endgame with two pieces less. But Getmanski has no problem to convert this to a win.

  48.28-22 17x30 49.25x34 14-20 50.26x17 18-22 51.27x29 24x42 52.17-12 42-48 53.12-7 48x25 54.7-1 25-39 55.32-27 19-24 56.1-12 20-25 57.12-23 39-17 58.23-34 17-3 59.34-18 3-20 60.27-21 16x27 61.18x36 20-14

and white surrendered.

8-13? Here black could win elegantly using   25-30! 53.33-28 or? 26-31!! and now both 54.37x26 23-29 55.26-21 (or   55.28-23 29x18 56.32-28 8-13 B+)   17x26 56.27-22 16-21! 57.36-31 26x37 58.32x41 21-27 59.22x31 30-34 and   54.28x19 31x42 55.19-14 42-47! are lost for white.

(it turns out that   32-37 63.27-22 17x28 64.21-17 12x21 65.26x17 results in a draw)   63.27x38 23-28 64.35-30 34x25 65.43-39 17-22! etc.
