Ten Hertog,H (2386) – Bok,B HSG Open 2015 Hilversum NED (3.1), 20.06.2015

  1. g3 d5 2.Bg2 Nf6 3.d3 c6 4.f4 Nbd7 5.Nf3 Qc7 6.0–0 e5 7.fxe5 Nxe5 8.Nxe5 Qxe5 9.d4 Qh5 White has shown no ambition in the opening which allows Black to equalize with no problem. 10. Nc3 [Still passive. 10. c4 was called for.] 10…Bb4 Diagram

By now black is already slightly better owing to the pressure he intends to put after castling on the semi-open “e” file as well as the option of undermining white’s pawn structure at some point by Bxc3. 11.Rxf6!? Gambling on a vague compensation along the dark squares however as long as long castling is still available black shouldn’t worry too much. 11…gxf6 12.Qf1 Bf5 13.e4 Bxc3 14.bxc3 dxe4 15.Ba3 Qg5! Protecting the vulnerable pawn before castling long and at the same time starting kingside dangerous assault with 16 ….h5.  16. Rb1 0–0–0 into the open file however black’s king position is easily defendable since while black’s own kingside attack seems unstoppable. 17. Bc5 Bg4?! [Stronger was the consistent 17…h5 18.Bxa7? h4! with a winning attack] 18.Bxa7 Qe3+ 19.Qf2 Qxf2+ 20.Kxf2 Rhe8 the material advantage is sufficient yet a final appealing finesse is still to come.  21. Ke3 Rd5 22.Bc5 Rh5 23.h4 Rf5 24.c4? Diagram

[Allows a nice counter combination.24.Re1 was essential.] 24…Rf3+! 25. Bxf3 exf3+ 26.Kf4 [While following 26.Kf2 Re2+ Black will collect too many white pawns] f5! The white king is all of a sudden in a mate net as 27…f6 followed by 28 …Re4# is threatened.  27. Kg5 Re6 28.d5 [The fashionable modern Dutch harakiri in action. The unpleasant alternative was naturally 28.Bf8 Bh3 29.d5 Rg6+ 30.Kf4 f2 etc.] 28…h6+ 29.Kf4 Re4# 0–1
