Behind Enemy Lines

World Chess Champion Bobby Fischer said every game had a “critical position,” and a player MUST be aware when a critical position arises on the board. The following game caused me to reflect upon the comments of the greatest Chess player of all-time.

Gonzalo Muniz (URU) FM (2281)

Herman C. Van Riemsdijk (BRA) IM (2285)

Open of Montevideo Marcel Duchamp Cup 2018 round 09

C68 Ruy Lopez, exchange variation

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Bxc6 dxc6 5. O-O Bd6 6. d4 exd4 7. Nxd4 Ne7 8. Nc3 O-O 9. f4 Re8 10. Nb3 f6 11. Be3 Nf5 (Not exactly a critical position. Nevertheless there is only one move for White to retain a small advantage, as all other moves leave his opponent with a small advantage.)

12. Bc5? Bxc5+ 13. Nxc5 (We have now reached the critical position. Black did not find the best move. Can you find it without consulting the clanking digital monster?)

13…Ne3? 14. Qxd8 Rxd8 15. Rf2 b6 16. Re2 Nc4 17. Nd3 Be6 18. h3 c5 19. Rae1 Na5 20. Rf2 Nc6 21. f5 Bf7 22. Nf4 Ne5 23. Ncd5 Ra7 24. Rd1 Re8 25. Re2 b5 26. Nd3 Nxd3 27. Rxd3 c6 28. Nf4 Bc4 29. b3 Bxd3 30. cxd3 Rd7 31. Rc2 Re5 32. Kf2 Kf7 33. Ke3 Rd6 34. a3 a5 35. g3 g5 36. Ne6 Rdxe6 37. fxe6+ Kxe6 38. b4 axb4 39. axb4 Kd6 40. Rf2 Re6 41. bxc5+ Kxc5 42. Rf5+ Kb4 43. h4 h6 44. d4 Ka4 45. Kd3 b4 46. d5 cxd5 47. exd5 Rb6 48. Kc2 Ka3 49. d6 b3+ 50. Kc3 Rc6+ 0-1

In the first position White should simple “advance to the rear” with Bf2. The line given by Stockfish at the ChessBomb is: 12. Bf2 Nh6 13. Qf3 b6 14. h3 Bb7 15. Nd2 c5 16. Rad1 Nf5 17. Qd3 Nd4 18. Be3 Nb5 19. Nxb5 axb5 20. Qxb5 (https://www.chessbomb.com/arena/2018-open-of-montevideo/09-Muniz_Gonzalo-Van_Riemsdijk_Herman_C_)

In the second position Black missed 13… Qe7 14. Nd3 Ne3.

Now that is a move one does not see every day!
