White to move. |

Shirov - Kramnik endgame... White to play: 1.c5! The endgame by blake78613: I quite like 1.c6 here, with the idea 1...bxa5 2.b6 ... Already it's hard to find a reasonable move for Black. |

1. b4 what about 1. b4 ? |

Break on through to the other side White has the nice King breakthrough starting with 1. Kd5! Rf1 2. Rh4 Rxf5+ 3. Kc6 Kg7 4. Bf8+! Kf7 5. Bd6 Rg5 6. Rh8 Rg8 7. Rxg8 Kxg8 White has a very nice Bishop maneuver that ensures him the game. 8. Kb7 f5 9. Kc8 Bh4 10. Bc7 Kf7 11. Bd8! Bf2 12. Bg5! Bb6 13. Bf4 a4 14. Bc7 and the d-pawn Queens. |

Very neat ending... |

Playing for a win with a pawn minus I have some compensation for the pawn because of the pressure on d4 but with correct play, White should be able to win. Or at least not lose. Play continued like this: 27...Red8 28. g3 g6 29. Kg2 h5 30. h3 Kf8 31. g4 Bg5 32. Rd3 Bf6 33. f4 b5 My idea was to create some space on the Q-side while at the same time trying to fix the pawn structure on the K-side, preferably with my pawns on white squares and my opponent's on dark squares. Also, it would be ideal if I could get the King to blockade on d5 so as to free one Rook for active operations on the c-file. There followed: 34. Kf3 a5 35. b3 b4 36. Ke4 Ke7 37. Rc1 Kd6, not very accurately played but at least I had an active plan in mind, whilst my opponent seemed to dabble. To be honest, White is close to winning here, he would just have to transfer the King on the d-file by clearing d3 from the Rook. My opponent thought otherwise and played a weaker move. 38. Kf3?, missing his chance to activate the King. 38...Bg7, freeing the f-pawn to move, if necessary, 39. Rc5, a seemingly active move but I wasn't against exchanging one pair of Rooks 39...Ra8?!, better was 39...hxg4+ 40. hxg4 f5 41. g5 Rh8 with good drawing chances, 40. Rxd5+?, a mistake, after this the King comes to d5 and is a very active blockader, better was 40. f5!, gaining space on the K-side and opening lines for the Bishop to come into play, 40...Kxd5 41. Rd1?, White is pushing himself into complete passivity, much better was 41. Re3 and the d-pawn is immune because of pin or the discovered check. Here the position is more or less equal, White has an extra pawn but his pieces are restricted by it and tied to defending it. Black has good prospects on the Q-side and White can't do very much on the K-side. 41...a4, creating a second weakness, 42. Be1, very passive, 42...axb3 43. axb3 Rb3, tactically defending the b-pawn, 44. Rd3 Bf8 45. Ke3, trying to activate the King, 45...Ra1!, the Black Rook stays active and keeps harassing the White pieces, 46. Ke2 hxg4 47. hxg4 Bd6, a secondary blockader is setup in case the King should decide to invade the White camp, 48. Bg3 Ra2+ 49. Kf3 Rc2! 50. Be1, guarding against the threat of Rc3, 50...f5, at last fixing the K-side pawns on dark squares, 51. g5 It seems like everything I had planned was accomplished and my opponent hasn't done anything positive with his position. 51...Rh2 52. Kg3? a bad place to put the King, 52...Rh1?, 52..Re2! wins, i.e. 53. Bf2 Bxf4+ 54. Kf3 Rd2 55. Rxd2 Bxd2 56. Ke2 Bxg5, 53. Rd1?, too passive 53. Bd2 keeps things together 53...Ke4, I couldn't resist the chance to attack with the King, but 53...Rf1 simply wins a pawn, 54. d5?, 54. Kg2 was the the last chance to stay in the game, 54...Bxf4+ 55. Kg2 Rh2+ 56. Kf1?, trying to keep everything defended, but in fact walking into a matting net, 56...Kf3 57. Kg1 Rg2+ 58. Kf1?, 58. Kh1 saves the mate but not the game, 58...Be3 There is no save from mate now, 59. Bf2 Rxf2+ 60. Kg1 Rg2+ 61. Kh1 Kg3 and mate on the next move. |

Queen Pirouettes 1. w White to play and win 2. w White to play and win The article gives a strong clue of course: the 'windmill' action of the queen in both studies. In the second, the windmill switches direction. Very neat! |
||||||||
|
Haven't looked at the second one yet... I like how the queen moved in that one - like a carousel of death! |

Was there a win? game This was a recent game I played probably played very poorly however it did result in an endgame that I found quite intriguing. It ended up becoming N+3p vs 2N so I couldn't loose, the question is could I win? I regret to say that I didn't have the patience to properly analyise the game however I did eventually find something that looked promosing. I thought there was a way to sac two of my exsisting pawns in order to have the tempo to bring my knight and king over to a position where they could support the final pawn. Turns out my opponen found a soulution to that. What are your thoughts on the endgame, was it infact an easy win and I'm just not a good enough player yet to realise this? |

@ thereaper1 -- A woodpusher's strategy many possible variations for me to chart the game moves out to the end, but I am writing to see if the stronger players might react and suggest improvements to my strategy. First, as you point out, after the exchange of Rooks on moves 46 and 47, White is not going to lose this game unless he blunders. Second, after the exchange of Rooks, the only likely way for White to win the game is by promoting a pawn. So my first conclusion is to keep all of White's pawns as long as possible. Then I notice that after move 52, White's pawn on a6 has effectively tied down Black's Knight on c8. If Black uses his c8 Knight to attack White's d or e pawns (even after they have advanced) then White can push his a pawn to the 8th rank. So White should push his d and e pawns, exchanging his Knight for either of Black's Knights if the opportunity presents itself, trying hard to preserve the two central pawns as long as possible. If Black takes the time to go after White's pawn on a6, I think that White can probably take advantage of the tempos required for Black to launch that attack, and White should get one of his central pawns to the 8th rank. If Black tries to defend the advance of White's two central pawns using his central Knight and King, without help from the Black Knight on c8, then I think White will be able to push through using his King and Knight for support. Constructive critical comments are welcome. |

thereaper's endgame... White's approach looked pretty much as I would have tackled that ending, too. If there is an improvement, it must be pretty subtle... I did try 65.Ne7, to see if that might make a difference. As expected: it didn't... Food for thought there. Interesting sort of endgame. Note, by the way, that had Black been silly enough to exchange a pair of knights in that ending, it would have been very winnable for White. |

Thanks for the insight I also tried 65.Ne7 myself in my annalysis when playing the game, however as ion points out it made no difference. |

I recently drew this endgame. Fritz thinks I had a win. What do you think? 44. hxg5 ( Fritz recommends 44. f4+ Kf6 45. hxg5+ hxg5 46. h5 and White has a winning advantage) ... hxg5 45. f4+ gxf4+ 46. gxf4+ Kd6 47. Kd4 Ke6 48. Bd3 Ba2 49. Be4 Kd6 50. f5 Bf7 51. Bb7 a5 52. Be4 Bc4 53. Bc2 Bf7 54. f6 Bc4 55. Bg6 Ke6 56. f7 Ke7 57. Ke5 axb4 58. axb4 Bb3 59. f8=Q+ Kxf8 60. Kd6 Bc4 61. Kc6 Ke7 62. Kxb6 Kd8 63. Be4 Kc8 64. Bc6 1/2-1/2 |

1. Houdini (1.5) thinks this is dead drawn. After 1 f4+ it wants to reply gxf4+ (which looks better than Kf6 to me)., and 2. yes, i'd play the capture on f4, exchange off on the Queenside and the black bishop can take care of the loose f-pawn as white's bishop is the wrong colour for the king's rook pawn |

I'm inclined.... In principle, White should 'avoid' pawn exchanges, but I think this principle needs qualification. Pawn exchanges are probably necessary at some point, so he should make them on his terms, not his opponent's. With that in mind, 44.f4ch seems to offer the better chances of a win. The defence 44.f4ch Kf6? 45.fxg5ch hxg5 46.h5 looks terrible for Black: the King will be driven back and permit an invasion by White's King into Black's position. After 44.f4ch gxf4 45.gxf4ch Kf6 the first thing I'd look at is what happens if White offers to exchange bishops: 46.Bd3 Bxd3 47.Kxd3 Kf4 48.Ke3 h5 49.Kf3 This looks like a zugzwang to me... 49... a5 50.Ke3! axb4 51.axb4 Kg4? Better would be ...Kf6 here, but White would definitely be on top. 52.Ke4 Kxa4 53.Kf3!! an absolute killer move: Black committed to the h-file and the White f-pawn free to run. This is one of those situations in which White, contrary to usual practice, would go for the piece exchange - in the knowledge that the pawn ending AT THAT MOMENT is winning for him. So Black would probably do better to decline the offer and move the bishop out of the way. After that, it seems very difficult for white to make much progress after, say 46.Bd3 Bf7 47.Kd4 Be6 48.Be4 Bc8 The game looks very drawish after this. The next thing to do for White, is to look around for alternatives to the bishop exchange offer at move 46. That's for another time... |
