Black lost time with the last set of moves, but every trade of minor pieces should dilute White's attacking chances. The operative word here is 'should'. } 11. Rd1 Nc6 12. e4 Bxg3 13. hxg3 cxd4 14. cxd4 dxe4 15. Nxe4 { Black has made all the right decisions so far. White's pressure on the h-file has to be weighed against the weakness of the d4-pawn and a king who might be in trouble if Black ever achieves ...e6-e5. } 15... Rc8 (15... Nb4! { A wonderful multi-purpose defensive resource. The knight vacates the c6-square, reducing the power of White's 16. Nf3-e5, and re-deploys to the d5-square where it defends its colleague on f6. } 16. Ne5 Nbd5) 16. Ne5 Nd5?? { Black's lone defender of the kingside leaves its post and, just like that, Black is completely lost. } 17. Qh5 h6 18. Ng4 Qe7 (18... f5? 19. Nxh6+ gxh6 20. Qg6+ Kh8 21. Rxh6#) 19.
