patzer2: <1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 6 5. Nc3 a6 6. Nxc6>
This move is currently in fashion among GMs. Also frequently played at Master level are 6. Be2 as in Wang Hao vs M Kobalia, 2008, 6. Be3 as in Radjabov vs Ivanchuk, 2008 and 6. g3 as in Svidler vs Rublevsky, 2007.
<6...bxc6 7. Bd3 d5 8. O-O Nf6 9. Qf3>
With this move, White steers the game into familiar territory -- since he previously played it in Leko vs Mamedyarov, 2007.
<9...Be7 10. Qg3 Nh5>
Perhaps worth trying is 10...O-O as in Karjakin vs Rublevsky, 2007.
<11. Qf3 Nf6 12. e5 Nd7 13. Qg3 g6 14. Bh6 c5>
Don't know if it's a novelty, but this is the only game with this move currently in the chessgames.com databse. I suspect we'll not see much of the move in the future as it makes it
difficult for Black to equalize.
Instead, Black can try 14...Bf8 which transposes to the two draw games M Vachier Lagrave vs V Laznicka, 2008 and I Kurnosov vs Movsesian, 2008.
<15. Na4 c4 16. Be2 Bb7 17. b3 Bc6 18. Nb2 Rb8 19. Nd1 Nc5 20. Ne3 Ne4 21. Qh3 Ng5 22. Qg4 c3 23. a3 Bb5?>
This not so obvious mistake appears to
give White a decisive advantage. Instead, Black can try and hold with
23... Ne4 (also recommended by <ezzy> above), when play might continue 24. Rfd1 Bh4 25. g3 Bg5 26. Bxg5 Nxg5 27. Qd4 Qa5 28. b4 Qb6 29.
Qxc3 Bb5 30. Bxb5+ axb5 31. Ng4 Ne4 32. Qf3 O-O with only a small White advantage.
<24. Bxb5+ axb5 25. f3!!>
This initiates a winning double attack combination, threatening to either win the trapped Knight with a pawn or spring a decisive attack on the King should Black try to create an escape square for his suffocating steed.
