1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O b5 6. Bb3 Bb7 7. c3 Nxe4 8. d4 Na5 9. Bc2 exd4 10. b4








   
10...d5?!
A dubious novelty. In the game Smeets, J - Beliavsky, A, Corus B/Wijk aan Zee (11) 2006 Black played 10...Nc4 11. Bxe4 Bxe4 12. Re1 12...f5?! and after 13. Bg5 Be7 14. Bxe7 Kxe7 (14...Qxe7) 15. Nbd2 Kf7 White could obtain an edge with 16. Nxc4 bxc4 17. Ne5+ Kf8 18.f3. Also 13. Qxd4!? is interesting, 13...d5 14. Nbd2 Nxd2 15. Bxd2 Qd6 16. a4 bxa4 17. Rxa4 c6 18. Ra5.
Probably 12...d5 is preferable, 13. Nxd4 c5 14. bxc5 Bxc5 15. f3 O-O 16. fxe4 dxe4 17. Rxe4 Qd5 18. Rh4 Rad8 19. Nd2 Ne3 20. Qf3 Nf5 21. Qxd5 Rxd5 22. Rh5 g6 23. Rxf5 Rxf5 24. N2b3 Rc8 25. Nxc5 Rfxc5, Goloshchapov, A - Malaniuk, V, Nova Gorica op 2003.
11. bxa5 dxc3 12. Qe1
Or 12. Re1!?.
12...Qf6?
More precise is 12...Bb4 13. Ng5 O-O 14. Nxe4 dxe4 15. Nxc3 Bxa5 16. Qe3 with a small advantage to White.








   
13. Bg5!
White attacks.
13...Qe6
The first player has a huge advantage and after 13...Qc6 14. Be3 Be7 15. Nd4 Qf6 16. f3 Nd6 17. Nb3 O-O 18. Bd4.
14. Nxc3 Bb4








   
15. Nxd5!
A powerful blow.
15...Qxd5
Or 15...Bxd5 16. Qxb4, 15...Bxe1 16. Nxc7+.
16. Qxb4 Nxg5 17. Rfe1+ Ne6 18. Be4








   
18...Qd6 19. Qxd6 cxd6 20. Bxb7
Winning.
20...Ra7 21. Bc6+ Ke7 22. Nd4 Kf6 23. Rad1
Black resigned. 1-0
