Yesterday, a solid method for improving in chess was presented, which involves learning only five positions per week.
Below are the solutions to the three positions that were published yesterday, so you can see how the training concept works in practice and become comfortable with it. You may have already looked at at least one of the positions. If you haven’t had a chance to examine any of them, I suggest you pause at the first one below, but be cautious not to scroll down too quickly, as you might accidentally see the solution just under the diagram. It’s pedagogically correct for you to form your own opinion about the position before checking what actually happened. Take at least 5 minutes and up to about 30 minutes to assess the position, followed by a proposed move or a series of moves. After you’ve done this, you can check the answer key and compare your thoughts with what actually transpired between Bogoljubow and Alekhine in the fourteenth match game of 1929. If your proposed solution went completely awry, try to learn from the game position and review it again in a week to see if you understand the key principle regarding play with opposite-coloured bishops. Don’t forget that ”repetition is the mother of learning,” and this certainly applies to serious chess training. However, your repetition should focus on attempting to comprehend the fundamental idea in the position and how it is executed. Otherwise, the forgetfulness curve will inevitably gradually eliminate what you haven’t grasped and therefore haven’t learned.
Position 86 – Middlegame – The Bishop Manouevre – White to move Bogoljubow – Alekhine, World Championship match 1929 (14)
19. Rad1! At first glance, this position appears to be balanced, but appearances can be deceiving. The reason is the presence of opposite-coloured bishops. This means that the player who seizes the initiative essentially gains an extra piece, as Black’s bishop cannot defend the white squares. 19. Bxb7? is met with 19… Rab8. The natural 19. Rac1 only leads to a rook exchange after 19… Rac8. 19… Rac8 20. Rd3! Rc7 21. b3 b5 22. Rf3 White is the first to exert pressure on f7, as Black’s rook lacks a similar pressure point against f2. 22… Qb6 23. a4 bxa4 24. bxa4 Qb4 25. Qa2 Qb2 26. Qxb2 Bxb2 27. Rb1 Bd4 28. Rb5 Ra7 29. h4 h5?! 30. Rb7! Rxb7 31. Bxb7 Rd8 32. Bd5 Rd7 Black’s rook has managed to trade the passive f8 square for a more active one, but it is still less active compared to the white rook, which has considerably greater mobility. 33. Rb3 Kf8 34. Rb5 Ra7 35. Bb7 Black’s rook is temporarily trapped. 35… Ke7 36. g3 Kd6 37. Kg2 Kc7 38. Bd5 Kd6 39. f4 f6?! 40. Bb3! White prepares Bd1 to exert pressure on the h5 pawn. Black’s …g6 can be met with f5. 40… Ra6 41. Bf7 Rc6 42. Rd5+ Ke7 43. Bxh5 Rc5 44. Rxc5 fxe5 45. Bf3! Kf6 27… Rxd5 28. exd5 and White is practically two pawns up, as the e5 pawn is not practically relevant. 46. Rd6+ Ke7 47. Rg6 Kf8 48. Bh5! Be3 49. Kf3 Rc3 50. Ke2 Bc5 51. Re6! g6 52. Bxg6 Re3+ 53. Kd1 Rxg3 54. h5 Kg7 55. Re5 Bb4 56. Ke2 Ra3 57. Be8 Rh3 58. Bd7 Rc3 59. Re6 Bf8 60. Ra6 Bb4 61. h6+ Kf7 62. Be6+ Kf6 63. Bf5+ Kf7 64. Ra7+ Be7 65. Ra5 Rc2+ 66. Kd3 Rb2 67. h7 Bf6 68. e5 Bg7 69. Ra7+ Kf8 70. e6 Be5 71. e7+ 1-0 A very instructive example that highlights the advantage of opposite-coloured bishops when one has the initiative.
Position 91 – Opening – The Rook Manoeuvre – Black to move
Karpov – Kasparov, World Championship match, Moscow 1985
11…Re8! It is not entirely straightforward to determine how the rooks should be developed in this position. Black wants to expand with …b5 in the near future, making b8 an attractive square. However, if …b5 is met with axb5, then a rook on a8 would be desired. The c-file is semi-open, so it’s natural to develop the rook there. Square d8 also looks useful as it’s generally good to place the rook behind a central pawn. Black can prepare …d5 or …e5 and be ready for White’s e5. Square e8 is also interesting, allowing Black to respond to White’s f5 and prepare …e5. Having the rook on f8 is beneficial when White plays g4-g5, as the break …f6 can be important. In this particular position, it makes sense to place the rook on e8, following the general rule that a rook is often most effective behind advanced pawns. 12.Bf3 Rb8 Black gets out of the long white diagonal and prepares a future …b5. 13.Qd2 Bd7 14.Nb3 b6 15.g4 Bc8 The knight needs room on d7 and the bishop is heading to b7. 16.g5 Nd7 17.Qf2 Bf8 18.Bg2 Bb7 19.Rad1 g6 20.Bc1 Rbc8 The rook no longer has a role on b8. 21.Rd3 Nb4 22.Rh3 Bg7 23.Be3 Re7! 24.Kg1 (Position 92) 24…Rce8!! Black anticipates White’s possible breakthrough with f5 and prepares for this advance with rook doubling on the e-file. It’s an incredibly skillful play by Kasparov. One could even say that Kasparov became world champion due to his ability to play with the rooks. 25.Rd1 25.Qh4 Nf8 doesn’t achieve anything for White. 25…f5! 26.gxf6 26.exf5 exf5 activates both of Black’s rooks. 26…Nxf6 27.Rg3 Rf7! The rook on e8 has lost its purpose, moving to the semi-open f-file. Notice how flexible Kasparov is with the rooks, constantly adapting to the new situation. 28.Bxb6 Qb8 29.Be3 Nh5 30.Rg4 Nf6 31.Rh4? g5! 32.fxg5 Ng4 33.Qd2 Nxe3 34.Qxe3 Nxc2 35.Qb6 Ba8 36.Rxd6? 36.Qxb8 Rxb8 would be a better continuation, even though Black’s position is preferable. 36…Rb7! Black’s kingside rook triumphs and decides the game. With this game, Kasparov secured his world championship title. Karpov didn’t quite keep up with these maneuvers involving the kingside rook!
Position 231 – Rook Endings – Black to move
Kasparov – Short, World Championship match, London 1993
46…Rc5! In the game, Short played the fatal 46…Ke6?? and lost after 47.Ke3 Kd6 48.Kd4 Kd7 49.Kc4 Kc6 50.Kb4 Re5 51.Rc1+ Kb6 52.Rc4 1-0) 47.Ra3 White prevents checks on c3. 47.a5 would have led to a draw after 47…Rc3+ 48.Kg4 Kxe4 49.a6 Rc8 50.a7 Ra8 51.Ra5 Kd4 52.Kf5 Kc4 53.Ke6 Kb4 54.Ra1 Kc5 55.Kd7 Kb6 56.Rb1+ Kc5! (56…Kxa7?? 57.Kc7 and White wins) 57.Rb7 Rh8! and the position is a draw. 47…Rc4! This move can be easily overlooked if you’re not aware of the idea. 48.a5 Rxe4 49.a6 Rf4+! Without this check, Black is lost. 49…Rh4?? 50.Ra5+ followed by a7 wins for White. 50.Kg3 Rf8 51.a7 Ra8 The position is a draw. A possible continuation is 52.Ra6 Kd5 53.Kf4 Kc5 54.Ke5 Kb5 55.Ra1 Kb6 56.Kd6 Rxa7 57.Rb1+ Ka5! Of course, not 57…Ka6?? 58.Kc6 and White wins. 58.Kc5 Rc7+ and Black has escaped the predicament by playing actively with the rook and king.
