The story is simple. We thought that Bf6 in fact won, not realizing that ...Bf5 was a saving grace. It was never intended to be a spoiler. |

Jan-25-12 | | gregkoch: It's interesting to me that White's attack on the dark squares <18.Bf6> can be matched by Black's defense on the light squares <18...Bf5>. |

Jan-25-12 | | David2009: Alekhine vs Sik, 1943 postscript: Fritz 12 considers 18.Qg3 best, and beats Crafty End Game Trainer (interactive link: http://www.chessvideos.tv/endgame-t...) in starting 18. Qg3 Rb4 19. h3 Kh8 20. Qe5 Rg8 21. Bf6 Qb6 22. Rg3 Bg4 23. Bxg7+ Rxg7 24. Rxg4 Rbxg4 25. hxg4 f6 26. Qxd5 Qxb2 27. Re1 Qb8 28. Qc6 Qf4 29. g3 Qd4 30. Qe8+ Rg8 31. Qf7 Qxg4 32.Qxf6+ Qg7 33. Qxg7+ Rxg7(?) 34. Re8+ and wins the Pawn ending. The variation is interesting as a way of examining the possibilities of the position. But it is meaningless as an objective test of whether the position as drawn or won, because Fritz 12 analyses to greater depth. Fritz 12 also beats Crafty EGT eventually with the game line 18.Bf6, but the position is level for a long time. Here are the moves Fritz found: 18... Bf5 19. Qg5 Bg6 20. Be7 Rfc8 21. Qxd5 Rxb2 22. c3 Kh8 23. h4 h5 24. a4 Qc7 25. g3 Qa5 26. Qd7 Rcb8 27.Qc6 R8b6 28. Qxc5 Rb1+ 29. Rxb1 Rxb1+ 30. Kh2 Qa6 31. c4 Rb2 32. Re5 Qxa4 33.Qd4 Qa2 34. Bc5 a5 35. Qf4 Re2 36. Be3 a4 37. g4 f6 38. Ra5 hxg4 39. h5 Bf7 40.Ra8+ Bg8 41. h6 Rxe3 42. hxg7+ Kxg7 43. Qxg4+ Kh6 44. Qf4+ Kg7 45. Qxe3 Qxc4 46. Ra7+ Bf7 47. Qg3+ Kh7 48. Re7 Kh8 49. Re3 Qd4 50. Rf3 Kh7 51. Rf4 Qd1 52.
Qh4+ Qh5 53. Qxh5+ Bxh5 54. Rxa4 and White is the exchange up. |

Jan-25-12 | | BOSTER: <alshatranjl> <Can we call this a bluff by Alekhine?>. I don't think that move 18.Bf6 is a bluff.
First of all this move created at least three very interesting traps. 1. 18...gxf6 is most primitive-mate in 3 after 19.Rg3+
2. 18...Rb4 19.Rg3 if Rxh4 20.Rxg7+ Kh8 21.Rg5#
3. 18...Qb4 19 Rg3 Qxh4 20. Rxg7+ Kh8 21.Rg5#.
If black played 18...Rfc8 19.Qg5 Kf8 20.Qxg7+ Ke8 21.Rxe6+ and white won. And even after the best defense 18...Bf5 19.Qg3 Bg6 20. Be5 I guess white is better. |

Jan-25-12 | | Waitaka: I went in a different line: 18.Qh6 gxh6 19.Bf6 ... 20.Rg3#, but as already pointer, this also can be defended. |

 | | sleepyirv: Speaking on something besides the puzzle being cooked... So you're playing the world champion in a game of a blitz- the circumstances are moot. You have gotten a lot of material off the board, the pawn position isn't too bad, but your queen is offsides (Alekhine was the master of getting his opponents pieces on the wrong side of the board) And Alekhine, THE WORLD CHAMPION, one of the greatest attacker offers a sacrifice 18. Bf6 What do you do?
You scoop it up and walk straight into a mate.
Why Sik? Why would you do that? |

Consider: 18.Bf6 Bf5! 19.Qh6?? gxh6 20.Rg3+ (I don't know what else you were looking for) Bg6 > Whoops. I didn't see bishop block. If I did, then ball game over for white. |

Jan-25-12 | | TheoNov: Found something while reviewing the game. Alekhine could have played a brilliant sac on move 13 which looks winning to me. Has anyone noticed this before? click for larger view13. Qxd5!! Qxb5 14. Rxe6+

 | | OhioChessFan: Nice find <theo> Looks winning to me. |
|
Jan-25-12 | | 1stboard: With regards to blacks 17th move, what is wrong with Bf5 instead of Rab8 ?? this would protect h7 and allow Bg6 to seal the g file. or am I missing something ??? |
|
Jan-25-12
 | | LIFE Master AJ: 18.Bf6. But I don't think it wins, I looked at it for 15-20 minutes, I could not refute 18...Bf6 & 19...Bg6. (Please! Someone tell me what I am missing here?) |

Jan-25-12 | | stst: No board, purely mental, see if got anything wrong..
18.g4(to make way for safe R parallel shift) d4

Jan-25-12 | | Bates79: What a "Sikophant" he is for taking that bishop on f6! |
|
Jan-25-12 | | TheBish: Alekhine vs Sik, 1943 White to play (18.?) "Medium/Easy"
Opposite-colored bishops often leads to a winning attack against the king, as in this game. 18. Bf6!
Preparing 19. Qg5 g6 20. Qh6 and mates. Now if 18...gxf6 19. Rg3+ Bg4 20. Rxg4+ Kh8 21. Qxf6#. Alternatively, 18...Kh8 19. Bxg7+ Kxg7 (or 19...Kg8 20. Bf6) 20. Rg3+ also mates. 18...Rb4 (Qb4 is similar) 19. Rg3! Rfc8
Or 19...Rxh4 20. Rxg7+ Kh8 21. Rg6#; 19...Rg4 20. Rxg4 Bxg4 21. Qxg4 g6 22. Qg5 followed by 23. Qh6 also mates. 20. Rxg7+ Kf8 21. Qxh7 and White should win.
~~~~~~
Well, I (and others) have egg on my face! Don't know how it totally escaped me that Black had an easy defense with 18...Bf5. My only consolation is that Alekhine's opponent missed it too, except it was a blitz game, so he had little time to find it! |

 | | kingscrusher: <TheoNov> I would have pointed this out if you had not already! It is fun to see if earlier sacrifices in a game would have worked just for some extra insights :) 13.Qxd5 is an effective sacrifice! |

 | | kingscrusher: This is really quite an amusing game thread btw for the puzzle of the day kibitzers. I think puzzles with spoilers should be posted more often :) |
