Catalan Opening E06

1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. g3 Be7 5. Bg2 0-0 6. 0-0 dxc4 7. Qc2 a6 8. a4 c5 9. dxc5 Bxc5 10. Nbd2 b5 11. axb5 Bb7 12. Nxc4 axb5 13. Rxa8 Bxa8 14. Nce5 Qc7?!TN [14. ... Bd6 15. Rd1 Qc7 16. Qxc7 Bxc7 17. Bg5 h6 18. Bxf6 gxf6 19. Nd3 Bxf3 20. Bxf3 Nd7 21. Rc1 Bd6 22. Rc6 Bb8 23. Ra6 Ne5 24. Rb6 Nxd3 25. exd3 Be5 26. Rxb5 Rb8 27. Rxb8+ Bxb8 28. b4 f5 29. b5 Ba7 30. Kg2 Bb6 31. Bh5 Kf8 32. f4 Ke7 33. Kf3 Bg1 34. h3 Bb6 35. g4 fxg4+ 36. hxg4 f6 37. Ke4 Kd6 38. Bg6 e5 39. Be8 Bg1 40. Kf5 Be3 41. Kxf6 exf4 42. Bc6 Kc5 43. Bf3 Kxb5 44. Kg6 Kb4 45. Kxh6 Kc3 46. g5 Kxd3 47. g6 Bd4 48. g7 Bxg7+ 49. Kxg7 ½ : ½ 余泱漪 (Yú Yāngyī) – So, 43rd Chess Olympiad, Batumi 2018] 15. Be3 Na6 16. Bxc5 Qxc5 17. Qxc5 Nxc5 18. Nd4 Bxg2 19. Kxg2 Rd8 20. Nxb5 Rb8 21. Nd6 Rxb2 22. Rc1 Nfd7 23. Nxd7 Nxd7 24. Rc7 Nf8 25. e3. As a consequence of her opening misconduct, Black must now lose a Pawn, eventually ending up defending a very difficult ending.


25. ... Rd2? Now, this may even be the wrong way. After 25. ... f5! 26. Ne8 Ng6 27. Nxg7 Ne5 28. Nxe6 Ng4 Black, though temporarily two Pawns behind, seems much closer to a draw. 26. Nxf7 Rd5 27. f4 Rd7 28. Rxd7 Nxd7 29. Ng5 Nc5 30. Kf3 h6 31. Ne4 Nd7 32. g4 Kf7 33. Ng3 Nc5 34. h4 Ke7


35. g5 hxg5? This is very wrong, of course. 36. fxg5! A concrete exception to the principle of taking with a Pawn toward the centre. Black must have felt as though she’d fallen into a nightmare, so she can’t do nothing but hope for an awakening. 36. ... Kf7 37. Ne4 Nd3 38. h5 Ne5+ 39. Kf4 Nd3+ 40. Kg3 Ne5 41. Kf4 Nd3+ 42. Kg4 Ne5+ 43. Kg3 Nc4 44. Kf4 Nb6 45. Nd6+ Ke7 46. Nb5 Nd5+ 47. Ke4 Kf7 48. Nd6+ Ke7 49. Nc4 Nb4 50. Kf4 Nc6 51. e4 Nb4 52. Nb6 Kf7 53. Nc8 Nd3+ 54. Ke3 Ne5 55. Nd6+ Ke7 56. Nb5 Kf7 57. Nd4 Nc4+ 0 : 1. White apparently lost on time in a winning ending, probably due to connection loss.
