Virny - Silva 1/2-1/2

17-21? Black is under heavy pressure, but here he could still escape using the combination   26-31! 34.37x26 17-21 35.26x17 27-31 36.36x27 23-29 37.34x23 19x39 38.30x10 9-14 39.10x8 3x43 etc.   34.36-31! 27x36 35.34-29 23x34 36.40x20 The white position is practically winning, because of the breakthrough opportunity on the weakened black left wing. 7-12 37.20-15 21-27 38.33-29 27-31 39.30-24 19x30 40.35x24 3-8 41.45-40 12-17 42.40-34 17-21 43.37-32 21-27 44.32x21 26x17 45.38-32 8-12 46.42-38 16-21 47.29-23 17-22 48.25-20 14x25 49.15-10 13-18 50.34-29?

Ndjofang - Domchev 1/2-1/2

39.31-26? With the attack   40.28-23! 19x28 41.32x23 white could get a decisive advantage. The exchange 12-18 42.23x21 16x36 loses after 43.30-24, so black must play   15-20, but after for example 42.31-27 14-19 43.23x14 20x9 44.37-32 white controls all strategic squares.   15-20 40.28-23 19x28 41.32x23 17-22 42.38-33 6-11 43.33-29 14-19 44.23x14 20x9 45.29-23 9-13 46.30-24 12-18! Although not necessary, this sacrifice is enough to secure a draw for black. 47.23x12 11-17 48.12x21 16x27 49.48-42 22-28 50.26-21 27x16 51.42-38 16-21 52.38-32 28-33 53.37-31 21-26 54.31-27 13-18 55.24-19 25-30 56.34x25 33-39 57.19-14 39-44 58.14-9 44-50
