12. b4 Rf6

Note the bishop is on c1

13. d5 Rg6 

Here the variation 14 Nd4 Qg5 15 g3 Ne5! leads to this position

(please note that 15..ed5 16ed5 Bd5 17 Bc4! led to White winning Kramnik-Polgar 2005) This exchange sac was played by Grishuk on 16 Nxe6 Rxe6! 17 de6 Qg6 with attack !

14. Bb2 c5  (another idea would be 14..e5)

15.Rad1 exd5 16. cxd5 Rc8

 17. Qb3 a6 18. Nd2 Nxd2 19. Rxd2 b5 20. Qd3 c4 21. Qd4 Nf6 22. Bf3 Qd7 23. Rc1 Re8 24. g3 Rh6 25. Bg2 Ne4 26. Rdd1 Qf7 27. a4 Re7 !

this moves protects g7 and b7, so the black queen can join the attack on h5.

Black has put a knight on e4 again ( the first one got exchanged on d2 with white's knight).

28.axb5 axb5 29. f3? Qh5!
