Feb-28-05		mulondabl: the puzzle was too simple even for a beginer like me

Feb-28-05		psmith: I did not get the continuation played in the game, but instead came up with 52 Rg7+ Kh8 53 Rf7 which wins handily, if not as flashily and quickly.

Feb-28-05		kevin86: This is from the Godfather to white on move 64:"Play ♖h8 let's make him an offer he can't refuse!"

Feb-28-05		DanielBryant: So simple, yet so elegant.

Feb-28-05		TheWhiteRider: Well said Daniel, Simple, yet elegant.

Feb-28-05		beatgiant: <euripides> <On move 54 Black seems to win> <e.g. 54...Rc2 55 hg> White appears to save himself with 54...Rc2 55. Kg2!, stopping the pawn after 55...b2 56. Rb7 Nc3 57. Nd4 Rd2 58. Nf3 b1(Q) 59. Rxb1 Nxb1 60. Nxd2 Nxd2 61. hxg5, which looks drawn. White's passed pawns tie up Black's king and knight, while White's king stops the d-pawn.

Mar-01-05		euripides: <beat> that's a very elegant perpetual on black's rook. I think Black has <54...Rc2 55. Kg2 b2 56. Rb7 Nc3 57. Nd4 Rd2 58. Nf3> Re2 59. Nd4 Re4 60. Rxb2 Rxg4+ 61. Kf1 Rxd4, when I think the passed pawn and extra knight, with rooks still on, outweighs White's potential two united passed pawns though it's not easy; or 59 Kf1 Rc2.

Mar-01-05		beatgiant: <euripides> Against the suggested 58...Re2 59. Nd4 Re4 in the line you posted, White replies not 60. Rxb2 as you gave, but <60. Nf5!> and I still don't see the win. For example, <54...Rc2 55. Kg2 b2 56. Rb7 Nc3 57. Nd4 Rd2 58. Nf3> Re2 59. Nd4 Re4> 60. Nf5 b1(Q) 61. Rxb1 Nxb1 62. Nd6+ Ke7 63. Nxe4 dxe4 64. hxg5. White will play f4 next, and the result is similar to the earlier drawish line where Black now has an e-pawn. If Black instead returns with 60...Re2, then 61. Nd4 and we are in the repetition again, so the other try for Black is 60...Rg4+ 61. Kh3 b1(Q) 62. Rxb1 Rf4, which leads to 63. Re1+ Kd7 64. Re7+ Kd8 65. Rf7 gxh4 66. Nd6 with a drawish situation.

Mar-01-05		euripides: <beat> Interesting. Black may still have winning chances with <54...Rc2 55. Kg2 b2 56. Rb7 Nc3 57. Nd4 Rd2 58. Nf3 Re2 59. Nd4 Re4 60. Nf5 Rxg4+ 61. Kh3> Rf4 62. Ng7+ Kd8 63. Ne6+ Kc8 64. Rxb2 Rxh4+. This ending would be good for Black in the absence of knights, because the White king can be cut off, and Black's knight looks better placed than White's. If 65 Kg3 Black has 65... Ne4+. But there's still quite a bit of tactics going on ....

Mar-01-05		beatgiant: <euripides> Good find, I now agree your line starting with 54...Rc2 gives winning chances for Black. White may some improvements over the line you posted above (such as 62. Nd6+ Kf8 63. Rxb2 Rxh4+ 64. Kg2 Rg4+ 65. Kf1 instead of your 62. Ng7+). Black still has the extra d-pawn, but White is well placed to block its advance while still keeping an eye on the other remaining pawns. I suspect the position is drawn, but it's hard to prove this. Just to be clear, the current suggestion is: 54...Rc2 55. Kg2 b2 56. Rb7 Nc3 57. Nd4 Rd2 58. Nf3 Re2 59. Nd4 Re4 60. Nf5 Rxg4+ 61. Kh3 Rf4 62. Nd6+ Kf8 63. Rxb2 Rxh4+ 64. Kg2 Rg4+ 65. Kf1.

Mar-01-05		beatgiant: Earlier on, my suggestion for White to try for a win is 44. Rxd7 Rxd7 45. Ne5 Rb7 46. f7 Rxf7 47. Nxf7 Rxa2 48. Rb8 Kg6 49. Nd8 a5 50. g4. Black's pawns are controlled and his king is getting boxed in, so it looks like White can win with careful play.

Jan-07-20		areknames: 64.Rh8+ Kxh8 65.g7+ Is this going to be Rh8 week?

Jan-07-20		agb2002: White is one pawn down. Black threatens Rf6. White can promote the pawn in three moves with 64.Rh8+ Kxh8 65.g7+ followed by 66.gxf8=Q and mate soon.

Jan-07-20		kevinatcausa: This was easier having already seen yesterday's puzzle.

Jan-07-20		Cheapo by the Dozen: Two Mondays this week!? Another rook sacrifice at h8. In this case it sets up the pawn fork and the queening. The only part of this that wasn't instantaneous for me was noticing that the new queen at f8 will be protected by the knight.

Jan-07-20		saturn2: Easy but full of error potential. 64.g7? (instead of Rh8) 64...Kxh7? (instead of Rf3)

Jan-07-20		Walter Glattke: Black threatens Rf3+ 65.-Kg8 66.gxf8Q+ Kh7 67.Qg7# / 65.-Kh7 66.gxf8Q Kg6 67.Kg4 b2 68.Qg7# B) 64.Nxf8? b2 65.Rb7 less good C) 64.g7? Rf3+ (saturn 2)

Jan-07-20		stacase: Way easier than yesterday.

Jan-07-20		Tabanus: I saw it. A variant is 64.Rg7+ Kh8 65.Rf7 Re8 66.Rf8+ Rxf8 67.g7+ Kh7 68.gxf8=Q Kg6 69.Kg4 b2 70.Qg7#

Jan-07-20		goodevans: <59...Ke8> might have been a very different story. Play may well have continued <60.g6 b2 61.g7 Rh1+ 62.Kxh1 b1=Q+ 63.Kh2 Qg6>. click for larger view Black now guards against promotion and threatens 64...Qg2#. The immediate 64.g8=Q+ Qxg8 65.Ra8+ Kf7 66.Rxg8 Kxg8 is no better than equal so white must find <64.Nc7+>. Now if black's K leaves the back rank then 65.Nxd5+ would be devastating so <64...Kd8> is forced after which <65.g8=Q+ Qxg8 66.Ra8+ Kxc7 67.Rxg8> gives white the advantage but with some work still to do.

Jan-07-20		TheaN: Interesting combo. Essentially it brings the g-pawn home but it's immediately mate as well. After <64.Rh8+ Kxh8 65.g7+ Kh7 (Kg8 66.gxf8=Q+ Kh7 67.Qg7#) 66.gxf8=Q Kg6 (else Qg7#) 67.Kg4!> lets end this right here and now with <68.Qg7#>. Of course White's won after Qg7+ and Qb2 for example but why make it harder than necessary.

Jan-07-20		zb2cr: 64. Rh8+, Kxh8(forced); 65. g7+. Black has only two moves: A. 66. ... Kg8; 67. g7xf8(Q)+, Kh7; 68. Qg7#. B. 66. ... Kh7; 67. g7xf8(Q), Kg6; 68. Kg4, Black (any move); 69. Qg7#.

Jan-07-20		gawain: Two days in a row the solution is Rh8+.

Jan-07-20		Damenlaeuferbauer: After long pondering, my old Hungarian friend Istvan finally found the mate in five moves with 64.Rh8+!,Kxh8 65.g7+,Kh7 (65.-,Kg8 66.gxf8Q+,Kh7 67.Qg7#) 66.gxf8Q,Kg6 67.Kg4! and mate in the next move! May his soul rest in eternal peace or may he play in heaven a game with the great Viktor L. Kortchnoi again!

Sep-23-24		offramp: Istvan be like I's winnin'.
