I think f4 followed by f5 wins on the spot: f4 Rb8 f5 exf5 Nd5! Qd8 c5! or f4 Bc6 f5 exf5 exf5 Qd7 hxg6 fxg6 5 +4.13 bxa5 bxa5 hxg6 fxg6 e5 dxe5 Bd3 (1.68) 6 +3.81 bxa5 (3.07) 6 +3.67 bxa5 bxa5 hxg6 fxg6 (3.37) 6 +3.72 hxg6 (3.43) 6 +3.72 hxg6 fxg6 (4.01) 6 +3.73 f4 (4.24) 6 +3.82 f4 Bc6 Rd4 Rc8 (4.53) 6 +3.83 Rhd3 (5.04) 6 +3.84 Rhd3 Rc8 Rf3 Bc6 Rf4 d5 (5.36) 6 +3.85 Rf3 (6.50) 6 +4.09 Rf3 Bc6 hxg6 fxg6 b5 Bb7 Rxf6 Nxf6 (6.70) 7 +4.02 Rf3 Bc6 Bd3 axb4 axb4 Ra8 Bc2 (8.27) 8 +3.87 Rf3 Bc6 Kh1 d5 exd5 exd5 hxg6 fxg6 Rxf6 Nxf6 (18.75) 8 +3.88 f4 (21.80) 8 +4.30 f4 Rc8 f5 axb4 axb4 gxf5 exf5 d5 fxe6 fxe6 (29.15) 9 +4.32 f4 axb4 axb4 Bc6 f5 exf5 exf5 (59.51) 10 +4.64 f4 (159.09) 10 +4.64 f4 Bc6 f5 exf5 exf5 Qd7 fxg6 fxg6 hxg6 (169.23) 11 +4.89 f4 Rb8 f5 exf5 Nd5 Qd8 Rf1 Bc6 hxg6 fxg6 (541.13) 12 +4.99 f4 Bc6 f5 exf5 exf5 Qd7 hxg6 fxg6 fxg6 (1570.23) Interestingly Hiarcs postion evaluator judges the position as won for white from the beginning. Either a bug or it gives it a high score for the mating net. regards Andy
