1. e4, c5
2. Nf3, e6
3. d4, cxd4
4. Nxd4, a6
5. Nc3, d6
6. a4, Nf6
7. Be2, Nbd7
8. 0-0, Nc5
9. Bf3, Be7
10. g3, 0-0
11. Bg2, Qc7
12. Be3, Rb8
13. f4!, Re8
14. e5, dxe5
15. fxe5, Nfd7

Knight has to back off.  Black's Queen cannot take the pawn because of 16. Bf4....

16. Rxf7!! ...

 A shocker!  Only at this point has Black realized that his King is exposed.

16. .... Kxf7
17. Qh5+!, Kf8

Not 17....Kg8 because of 18. Qxe8.  If 17....g3, then 18. Qxh7+ Kf8, 19. Bh6 mate.

18. Rf1+, Nf6
19. exf6, Bxf6
20. Ndb5!, axb5
21. Nxb5, Qd7

The Knight at c5 is lost anyway, and the Black Queen has nowhere to go.

22. Qxh7, Qe7

Vishy may have other plans.  Now, Black defends his Knight.

23. Rxf6!! ....

Another stunner!  Now, if 23....gxf6, then 24. Bh6+ leads to mate.

23. .... Qxf6
24. Bxc5+, Re7

If 24.....Kf7, then 25. Nd6+ and White wins instantly.

25. Qh8+, Kf7
26. Nd6+, Resigns

Black's King can only go to g6, and mated after 27. Be4+ Kg5, 28. Qh4+.

Fantastic!
