Bc2 Nh5 15. e5! f5 16. exf6 Ndxf6 { This is an instructive error in evaluation that many club players make: Black has successfully defended the immediate mating threat on h7. But Black has failed to understand that the way he had to defend it, creating new holes after pushing ...f7-f5, was White's actual goal. } 17. Qg6+ Ng7 18. Qxh6 Qd5 19. Be5 Nfh5 20. Qh7+ Kf7 21.
