Protects the h7 pawn and adds pressure on d5.

19. Bf3, Bxg5
20. hxg5, Qxg5
21. Bb4, Rxd5

22. Rxd5, Bxd5
23. Rh5?? ...

To an untrained eye, this may look like a good move, winning an extra piece.  But Black's reply shows this to be a blunder.  White's best chance to equalize is 23. Bxf8 Kxf8, 24. Qxh7 f6, 25. Qh3 Be6, 26. Qh8+ Ke7, 27. Qh2 Qe5, 28. Qh4 Kd6, 29. Ka1 Kc7, 30. Qh7 Qg5, with a clear (but not yet decisive) Black advantage.

23. .... Qxh5!!

White resigns.  If 24. Bxh5, then 24..... Be4, 25. Qxe4 Rxe4 leaves Black with material advantage.  Impressive victory for Vishy Anand.
