Sicilian Najdorf Opocensky

Same idea as Marshall Attack. First out-of-book move is 6 Be2, letting the computer compute which Najdorf variation to play.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be2 e5 7. Nb3 Be7 8. Qd3 Be6 9. O-O O-O 10. Rd1 Nbd7 11. Qg3 Kh8 12. Be3 Rc8 13. Bf3 Nb6 14. Nd2 Rg8 15. h3 Nbd7 16. Nf1 b5 17. a3 a5 18. Nxb5 Rxc2 19. Nxd6 Qb8 20. Nf5 Bxf5 21. exf5 Rxb2 22. Bc1 Rb3 23. Qh4 Bc5 24. Be3 Rxa3 25. Rxa3 Bxa3 26. Qc4 Rf8 27. Bc6 Qc7 28. Qa4 Bd6 29. Bxd7 Nxd7 30. Rc1 Qb7 31. Rd1 Qc7 1/2-1/2 (Draw by repetition)

The variation 28. Rxd7 is interesting as Glaurung thinks white is losing (so avoids that move and goes to draw), whereas another chess engine (Spike) thinks white is winning.

Here is the full log.
