It's better to keep this bishop with 12. g2f3  12... e4c5  13. b2b4 [%c_effect b4;square;b4;type;Interesting;persistent;true] An interesting theoretical novelty. 13... c5a4 A knight on the rim is not always dim. The knight gets ready to go to b6 and protect the important d5-pawn. 14. f3f4  14... d8d7  15. d1f3  15... e8g8  16. f1d1  16... a8d8  17. b1d2  17... f7f6 a good move, trying to break White's pawn chain. 18. f3h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] Forcing Black to release the tension. 18... f6f5  19. h5f3  19... g8h8  20. d2f1  20... d5d4 [%c_effect d4;square;d4;type;GreatFind;persistent;true] Black can't wait any longer. 21. c2a4  21... b5a4  22. c1e3  22... d7e6  23. e3d4  23... e7b4 [%c_effect b4;square;b4;type;GreatFind;persistent;true] 24. f1e3  24... b4e7 The game is played at a very high level. The position is balanced. 25. f3e2  25... c6a5 [%c_effect a5;square;a5;type;Inaccuracy;persistent;true] It turns out we never really know when the knight on the rim is really dim. 26. c3c4  26... a5c6  27. d4c3  27... e7c5  28. e3d5  28... c6e7 [%c_effect e7;square;e7;type;Mistake;persistent;true] Now the game goes downhill for Black. The position is still acceptable after 29. d5c7  29... e6c6  30. c3a5  30... d8d1  31. a1d1  31... c6h6  32. e2f3 White is a pawn up and has a better pawn structure. The bishop is ready to go back to c3 and the knight to d5. The position is winning, and Moussard plays good moves until the end. 32... e7c6  33. a5c3  33... c6e7  34. d1d7  34... f8b8  35. g1h2 [%c_effect h2;square;h2;type;GreatFind;persistent;true] 35... e7g6  36. e5e6  36... c5f8  37. c7d5  37... g6h4  38. f3g3  38... b8e8  39. e6e7  39... f8e7  40. d7e7  40... e8e7
