Difesa Francese, Winawer
1. e4 e6 2. d4 d5 3. Cc3 Ab4 4. e5 b6 5. a3 Af8 For a time Robert Byrne, the American grandmaster, enjoyed considerable success with 5...Axc3+ 6 bxc3 Ce7 7 Dg4 but apparently he found a clear refutation because this sharp defence has dissappeared from his opening repertory. "Undeveloping" pieces though as with 5...Af8?! has little to recomend it. 6. f4 Cc6 Intending to castle Queenside. If 6...c5 7 Cf3 Cc6 8 Ce2?! gives White a clear advantage. 7. Cf3 Ch6 8. Ad3 Ab5 was more precise. 8...Cf5 9. Ce2 h5 ...Ch4!? was a good chance to free Black's game slightly. 10. g3 Ab7 11. c3 Dd7 12. Dc2 O-O-O 13. b4 f6 14. Ad2 Rb8 15. O-O Cfe7 Better was 15...Ae7 and White would answer 16 a4. 16. Tfb1 h4 Black takes a last chance for counterplay.

Dd2 Ce5 28. Tf1 Cd5 29. Af5? De2 with a winning endgame in sight. 29...Cf3+ 30. Txf3 Dxf3 31. Ae4 Dxa3 32. Dxd4 Dc1+ 33. Rf2 Tf8+ 34. Cf5 Cc3? 34...Df4+ and 35...Tf5 wins for Black. 35.

A very clever trap considering it was 5 minute chess. 41. Rg4 or 41 Rh3 Df1+ 42 Rg3 De1 and draws. But being ahead on time I decided to play for a win. 41...Ce3+ 42. Rf4 Cxf5 43. Rxf5 Dxb4 44. Tg7+ Rc8 44...Ra6 gave Black more chances for a win. 45. Ae4 Df8+ 46. Rg6 De8+ 47. Rf5 1/2-1/2
