Twin Cities Chess Club, 9/20/05, per Fritz

This is the position in question from my previous post. Against the best defense there is no forced checkmate, but there is a win after the correct move (guessed correctly by both The Java Man and Bahus) 9. Bxh7+!

Now, we have to examine black's possible responses.

9. ... Kh8 10. Ng5 and now Black must give away material to avoid mate (10. ... g6 {Nxe5!? prolongs the inevitable} 11. Qf3 Nf5 12. Bxg6 and the hammer will fall.

9. ... Kxh7 10. Ng5+ and now

10. ... Kh6?? 11. Nxf7 wins the queen, as both JavaManIssa and Bahus remarked

or 10. ... Kg8 11.Qh5 Re8 12. Qh7+ Kf8 13. Qh8+ Ng8 14. Nh7+ Ke7 15. Bg5+ Nf6 16. Qxg7 (which shows how hard the follow through was to calculate in g/45)

or 10. ... Kg6 and now White has two possibilities:

11. Qg4 (which I played in a similar position but my opp found a way to capitalize on the weak d4 pawn) f5 12. exf6 Kf6 13. Nh7+ Kf7 and Black has a slight advantage after getting two minor pieces for the rook and pawn

11. Qd3+! (the correct way to proceed, which I never even considered OTB) f5 12. h4! (even though I didn't consider Qd3+, I did see the possibilities of h4 after Kg6) Qe8 13. h5+ Kh6 14. Nxe6+
