Ba6 9. e4 O-O 10. Bg5 h6 11. Bh4 g5 {Whether now or after White plays e5, g5 
will have to be played, so Black decides to get it out of the way.} 12. Bg3 d6 
13. f4 Na5 14. fxg5 hxg5 15. O-O Nh5 {#} 16. Bxd6 $3 {The sheer imagination 
and depth are flabbergasting.} Qxd6 17. e5 Qe7 18. Ng3 $1 {This seemingly 
innocuous move is in fact a deflection and not an exchange!} Nxg3 {#} 19. Rf6 
$3 {Down two pieces, White ensures the kingside remains cut off with this move. 
} (19. hxg3 $6 f5 {and the attack is harder to conduct.}) 19... Kg7 {#} (19... 
Bxc4 {to try and take some of the steam out of White's attack by exchanging 
pieces, doesn't quite do it.} 20. hxg3 Bxd3 21. Qxd3 {The problem is that 
White still has a myriad of threats, whether the simplistic Qd2-Qxg5, to Raf1 
with queen or even a d5 thrust if called for.} {A sample line might go} Kg7 22.

21. hxg3 Nb7 {Desperately trying to bring some support for f7} 22. Raf1 Nd8 23. 
Qe4 Qb7 24. d5 Rh8 {#} 25. Qg6+ $3 {Just incredible.} fxg6 ({If} 25... Kf8 { 
then} 26. dxe6 {and there is no defense against Rxf7+.}) 26. Rxg6+ Kh7 {The 
final windmill is an inescapable mating net.} 27. Rxg5+ Kh6 28. Rg6+ Kh7 29. 
Rg4+ Kh6 30. Rf6+ Kh5 31. Rh4+ {The next move is mate.} 1-0
