After 11-17? van der Wijk realized his advantage using 48.34-29! 35-40 49.29x20 18-23 50.28x19 13x15 51.33-28! 8-13 52.27-22 17-21 53.28-23 9-14 54.22-17 14-19 55.17x8 and black resigned. In the position of the diagram Silva could have escaped using the sacrifice ≡ 35-40! 48.34x45 11-17! and now for example 49.37-31 24-29 50.33x24 18-22 51.27x7 8-12 52.7x18 13x42 with a draw.
