12. cxb5 Nf6h5
? A dangerous move, as there's a threat behind the knight at f3. Better, Re8, protecting the e-pawn.
13. a4 c6
Leaving the knight at h5 invites trouble.
14. Nf3xe5
takes the offered pawn, and threatens the knight.
14... cxb5
?? Nf6, Nf4 or Bxe5.
15. Qd1xh5 Qd8e7
loses the b-pawn?
16. Ne5g4
Opens the diagonal to g7 and brings the knight to attack f6 or h6.
16... a6 17. Qh5h6
?! A useless move, but I just couldn't resist. gxh6 Nxh6 1-0.
17... f6
! The best defense.
18. Qh6e3 Bd6e5
Not really crucial anymore as the f6 pawn protects the king position along the diagonal.
19. Ng4xe5 fxe5
now the e-pawn is difficult to protect, being blocked and isolated, and when it falls, the diagonal is open again.
