Jul-15-12  bachbeet: Like Nunn, I thought Bxh7+ was the right move.
Jul-15-12  James D Flynn: 24.Bxe5(not 24.Bxh7+ Kf8 25.Qh5 Nf6 26.gxf6 Bxf6 an d the Black K has escape squares on e7 and d7)Nxe5 25.Bxh7+ Kf8(if Kxh7 26.Qh5+ Kg8 27.Rh4 Ng6 28.Qh7+ Kf8 29.Qh8+ Nxh8 30.Rxh8#) 25.Qh5 Rb8 26.Nd4 Bd8 26.Nf5 f6 27.Bg6 Nxg6 29.Qxg6 Re7 30.Rh4 Kg8 31,Qh7+ Kf8 32.Qh8+ Kf7 33.Qxg7+ Ke8 34.Rh8# Now for the game.

  FSR: I'm guessing that it begins 24.Bxe5 Nxe5 (24...dxe5? 25.d6) 25.Bxh7+ Kxh7 26.Qh5+ Kg8 27.Rh4 Bxg5! (28.Qxg5? Nf3+). But then I don't see anything good for White. I notice that the game finished 0-1, so maybe it's a spoiler.

Is this line 28.Qh8# would be a pretty good option, no?

Jul-15-12  DarthStapler: I got the Bxe5 idea
Jul-15-12  agb2002: White has the bishop pair for a bishop and a knight.

The poorly protected black castle invites to play 24.Bxh7+:

A) 24... Kxh7 25.Qh5+ Kg8 26.Bxe5

A.1) 26... Nxe5 27.Rh4

A.1.a) 27... Ng6 28.Qh7+ Kf8 29.Qh8+ Nxh8 30.Rxh8#.

A.1.b) 27... f6 28.g6 Nxg6 29.Qxg6

A.1.b.i) 29... Bf8 30.Rf2 Qe7 (30... Qf7 31.Rh8+ Kxh8 32.Qxf7) 31.Nd4 and White's attack looks overwhelming.

A.1.b.ii) 29... Qd7 30.Rh7 Bf8 31.Qh5 with the winning threat 32.Rh8#.

A.1.c) 27... f5 28.Qh7+ followed by 29.Qxf5+ seems to recover the piece, keep the extra pawn and the attack.

A.2) 26... dxe5 27.Rh4 f5(6) 28.g6 Bxh4 29.Qh7+ Kf8 30.Qh8+ Ke7 31.Qxg7#.

A.3) 26... Bxg5 27.Bxg7 Kxg7 28.Qxg5+ Kf8 29.Rh4 + -.

B) 24... Kh8 25.Qh5 + -.

C) 24... Kf8 25.Bf5 and White stands much better.

Jul-15-12  agb2002: I feel like starting again with Reinfeld's first book of chess....
Jul-15-12  BlackSheep: Whie to play and lose , hmmm , Qf3 any good .
Jul-15-12  newzild: I, too, fell for the knight fork.

Instead of 24. Bxh7+?, I would suggest 24. Kh1, setting up the combo for real.

Jul-15-12  newzild: <Oxspawn: Sunday 15 July
Does chessgames really have to use the word ‘insane’ when it means ‘extremely difficult’? A one-off might be excusable slip, but repeated every week it seems gratuitously offensive; insanity and difficulty not being closely related concepts.>

Perhaps the puzzle is so difficult as to drive one insane while trying to solve it?

Jul-15-12  Patriot: <agb2002> Don't feel so bad. We're in the same company as John Nunn. :-)
Jul-15-12  andyatchess: Not a fan
Jul-15-12  Abdel Irada: <Disorient Express?>

This puzzle *is* a spoiler, then. I looked over the kibitzes to see if anyone else had found a solution I'd overlooked, but was unsurprised to find there didn't seem to be one.

This is a bit disappointing in a way, though, because if the "solution" 24. ♗xe5 had worked, the end would have been reminiscent of one of my own favorite games in which Black started with a bishop sac to clear the third rank, then finished with a queen-and-rook sacrifice on h2 followed by mate with the other rook.

Jul-15-12  Abdel Irada: This usage of "insane" is an example of the kind of faddish pop slang that remains trendy (like "trendy") for a certain number of years, and then becomes a quaint relic of drollery, a stylistic period piece comparable to mullets, plastic lawn flamingos and giant hood ornaments. In due time, it will take its place alongside such kitsch in the rubbish bin of cultural history.
Jul-16-12  qqdos: <Abdel> <newzild> did not use "insane" in the "trendy" sense you imply. His phrase "to drive one insane" has a very much longer and well-embedded pedigree.

  scormus: <Patriot: Regarding complaints that this isn't a puzzle .... The question is, do you want to become a better player or a better puzzle solver?>

A very well made point. It reminds me of when I was at school, we thought every question should have a complete right answer. The first time we had a question that didn't ... half the class was complaining about it being unfair.

<CG> great pun

  tpstar: <great pun> Agree. ;>D

I wonder if it made the Top 100?

Jul-16-12  kevin86: The sac was "brilliant" BUT alas,was unsound.
Jul-16-12  Abdel Irada: <qqdos>:

I am apparently guilty of insufficient specificity. The usage to which I referred was that of CG.com, not <newzild>.

Sep-18-12  Abdel Irada: After this game, Nunn was heard to mutter, "How could I let this gnome Csom ski all over my position?"
Jan-21-14  mandy64: The sac was not brilliant. Csom'a move is really spectacular, I would have never seen it, but the simple 31..f6 is easy to see, and good enough. If 32. Nd4 (the only way to continue the attack) then 32..Re4 wins.
Nov-15-14  Ch3st: Regards to Mandy64 if he moved F7 to f6 on move 31 move 32: Queen h6-g7 checkmate for king on g8...why Nd4...and not just win. I will point out that white will ultimately still loss this match, but if black doesn't make the right choices so will he. Black to constantly keep White's king in check to make sure he couldn't move his queen on h6 to g7. This is just what I've analozed and if put the pieces anywhere else except a few exceptions of course but here is the list: Kg1-f3 ; Qc7-c3, Kb3-d2 reminding (he can't take ce1 (cd1-e1-check-ke8-f8 etc etc), ce8-f8-check, kf7-cf8, queen c7-d8-check, kf8-f7, queen d8-cg4, should I exploiate the other 56 moves until white ends up with his knight on b8 and black has his pieces a6 - b4 - cf7 - g3 - f7 - King g6
Nov-15-14  Ch3st: Knight B3-D2 my bad as well as analyzed* Lolol White's King will be on D3 at the end left that out
Nov-15-14  Ch3st: King g1-f2 I should really look at my post before I post them sorry.
Jul-28-15  mandy64: @ Ch3st: if 31..f6, the queen at c7 defends the g7 pawn, that is the purpose of the move.
