rnkrbbnq/pppppppp/8/8/8/8/PPPPPPPP/RNKRBBNQ w KQkq - 0 1

Position #666

1. e4 e5 2. Nf3 g6 3. Nc3 c6 4. g3 d6. Perhaps Black should look for something more programmatic. 5. d4 Bd7 6. Rd3. White prepares to castle on the a-side. 6. ... Na6. Black, too, prepares to castle on the a-side. 7. a3 Bh6+ 8. Bd2 Bg7 9. Be3 exd4 10. Bxd4 Nc5 11. Rd2 Nf6? “[...] a pretty poor move. Levon, who was already in a difficult position had to go for 11. ... f5!. However, the move 11. ... Nf6 showed a complete disregard for this Pawn break and the fight for space”, Ganesh Dorairaj wrote in his notes for ChessBase India. 12. Ng5 Rf8. Castling on the h-side would be an awful idea due to 13. e5. 13. 0-0-0 0-0-0. But, even after Black’s castling on the a-side, the push of White’s Pawn to e5 turns out to be disruptive. 14. e5 Ng4 15. f4 Ne6 16. Nxe6 Bxe6 17. h3 dxe5 18. Bxa7 Nf6? Ganesh Dorairaj calls 18. ... exf4 “a much better try”, but he is quite wrong as it would follow 19. Ba6! very much the same! Another try might be 18. ... e4, but after 19. Na4! Black’s castle is about to fall apart.


19. Ba6! Threatening Qh1xc6#. 19. ... e4 20. Qg1! Rxd2. If 20. ... Nd7 then 21. Rxd7! Rxd7 22. Qb6 finis. 21. Bxb7+! Kxb7 22. Qb6+ 1 : 0.
