The Semi-Slav Defence.
5. e3 Nbd7 6. Bd3 dxc4 7. Bxc4 b5 8. Bd3 Bd6 9. O-O O-O 10. Qc2 Bb7 11. a3 Rc8 12. Ng5
After 12. b4 Black gets sufficient counterplay with 12...c5! 13. bxc5 Bxf3 14. gxf3 Nxc5 15. dxc5 Rxc5 16. f4 Nd5 17. Bb2 Nxc3 18. Bxc3 Qc7 19. Rfc1 Rc8 20. Bxh7+ Kh8 21. Bd3 Rxc3, Topalov, V - Kasimdzhanov, R, London FIDE GP 2012. Or 16. Bb2 Bxh2+ 17. Kxh2 Rh5+ 18. Kg2 Rg5+ with perpetual check in Malakhatko, V - Khismatullin, D, Chigorin Memorial, St Petersburg 2012.

   
12...c5!
A novelty. The home opening preparation plays a very important role in the modern chess. In the game Wojtaszek, R - Negi, P, Bundesliga, Germany 2012 White had good compensation for the pawn and the initiative after 12. Ng5 Bxh2+ 13. Kxh2 Ng4+ 14. Kg1 Qxg5 15. f3 Ngf6 16. b4. Or 12. Ng5 h6 13. Nge4 Be7, with a small edge to White, Stefanova, A - Ushenina, A, Women's World Chess Championship, Khanty-Mansiysk 2012.
13. Nxh7
13. Bxh7+!? deserves attention, 13...Kh8 14. f4 g6 15. Bxg6 fxg6 16. Nxb5 Bb8, with a wild game.
13...Ng4! 14. f4
Probably 14. h3!? is more precise, 14...Bh2+ 15. Kh1 Qh4 16. d5 Rfd8 17. f4 (17. dxe6? Qxh3) 17...b4, with counterplay.
14...cxd4 15. exd4
Here White could try 15. Nxf8 Bxf8, and Black has compensation for the exchange.

   
15...Bc5!!
A powerful move! World Champion Viswanathan Anand sacrifices his bishop.
16. Be2?!
After 16. dxc5 Nxc5 17. Nxf8 Qd4+ 18. Kh1 Nxd3 19. h3 Ndf2+ 20. Rxf2 Nxf2+ 21. Kh2 Black has a small advantage.

   
16...Nde5!!
Great tactics! White can take a rook, a bishop or a knight.
17. Bxg4
After 17. fxe5 Qxd4+ 18. Kh1 Black checkmates with a queen sacrifice: 18.Qg1+! 19. Rxg1 Nf2, a smothered mate.
17...Bxd4+ 18. Kh1 Nxg4 19. Nxf8

   
19...f5!
Winning. Black's attack is unstoppable, Black's bishops are very strong.
20. Ng6 Qf6 21. h3 Qxg6 22. Qe2 Qh5
Or 22...Qh6.
23. Qd3

   
23...Be3!
The last blow. 24. Bxe3 Qxh3+ 25. Kg1 Qxg2 or 25...Qh2, a checkmate!
White resigned. 0-1

After the game. Viswanathan Anand: "... classic Rotlewi-Rubinstein... It was the same concept: bishop on b6, bishop on b7, and Rubinstein's version was even rook takes c3, h3, but essentially the same idea: queen h4 and queen takes h3, all these ideas work".

Levon Aronian: "I should study openings better".
