37.41-37?!

Until now Groenendijk didn't manage to obtain a concrete advantage. But here he grabs the opportunity to complicate the game.

3-8!

Of course the combination 42.27-21 16x36 43.37-31 36x27 44.32x3 would be suicidal now.

42.47-41!!

More logical was 42.47-42 8-12 43.39-34. At first sight this looks problematic for black: 22-28? 44.33x22 17x28 45.27-22 18x36 46.34-29 W+. But using the combination 23-28 44.32x23 18x40 45.27x29 16-21 46.35x44 21-27 47.31x22 17x50 black can escape with a draw.

17-21?

Yoan becomes the victim of a tactical trap. Instead he should have played 8-12! 43.41-36 17-21 44.31-26 22x42 45.26x8* 13x2 46.38x47 and black has the advantage.

43.31-26 22x42 44.26x6 42-47 or? 45.6-1 47x36 46.32-27! 36x22 47.33-29 23x32 48.1x37 and black resigned.

Thomy Lucien Mbongo - Karol Dudkiewicz 2-0 (26-4-2018)

1.32-28 17-22 2.28x17 12x21 3.34-29 7-12 4.40-34 11-17 5.45-40 6-11 6.33-28 19-23 7.28x19 13x33 8.39x28 9-13 9.37-32 14-19 10.31-27 10-14 11.44-39 1-6 12.38-33 21-26 13.41-37 5-10 14.43-38 17-21 15.49-44 20-25 16.27-22 18x27 17.28-23 19x28 18.33x31 14-19 19.32-28 10-14 20.37-32 26x37 21.42x31 21-26 22.47-42 26x37 23.42x31 16-21 24.46-41 21-26 25.41-37 4-9 26.39-33 14-20 27.44-39 19-24 28.48-43 12-18 29.50-45 2-7 30.31-27

7-12(?)

After 11-16 the position would be about equal. But after this logical move Mbongo was able to grab the initiative.

31.28-22! 24-29 32.34x23 18x29 33.33x24 20x29 34.36-31!

White leaves his opponent no time to reorganize his defence with 9-14.

12-18 35.39-34! 18-23 36.43-39 13-19?

This allows Mbongo to decide the game using a combination. Also 11-17? 3.22x11 6x17 4.39-33 and 15-20? 37.35-30 were lost for black. But with 11-16! 37.38-33 29x38 38.32x43 15-20! 39.34-30 25x34 40.40x18 6-11 41.39-33 11-17 42.22x11 16x7 black could still make a draw.

37.27-21 26x28 38.39-33 28x30 39.35x2
