  agb2002: Black has a bishop for a rook.

White threatens Qxe6+.

The black queen can reach b1, b3, b5 and d1 from d3. Therefore, 34... Rxb3+ 35.Bxb3 (35.Rb2 Qxb2#) 35... Qd3+:

A) 36.Bc2 Qb5+ and mate in two.

B) 36.Rac2 Qxb3+ and mate next.

C) 36.Rcc2 Qd1+ 37.Rc1 Qxb3+ and mate next.

Jan-23-18  saturn2: Without the bishop Be2 on board the puzzle would be easier.
Jan-23-18  malt: <34...R:b3+> 35.B:b3 Qd3+ 36.Bc2 (36.Rac2 Q:b3+) 36...Qb5+ 37.Bb3 Q:b3+ and #
Jan-23-18  Bubo bubo: I went astray on the second move: 35...Bd3+?, with the intention to answer 36.Rcc2 with Qd1#, the white bishop's diagonal being blocked by the pinned rook. Nice plan - if not for the nasty fact that the d-file is now blocked as well. :-(
Jan-23-18  nok: <I went astray on the second move: 35...Bd3+?> Ditto, with ...Qg1#. Which would be great if not for Qxg1.
Jan-23-18  zb2cr: First Tuesday puzzle I have missed in a long while. Did not see the follow-up to 35. ... Qd3+; 36. Rcc2 pointed out by <FSR>, above.
Jan-23-18  morfishine: More of a Wednesday or Thursday level problem. Tricky and thus time consuming to sort out the correct move order
Jan-23-18  Pasker: Not too easy..but okay.

  Fusilli: This is the eighth time <CG> uses a puzzle I suggested, which I am going to use to give a little piece of advice.

Often folks kibitz "Move X would be a great Thursday puzzle." When we kibitz, we attract attention to the game in question. When we kibitz something like that, we spoil the puzzle! <CG> likes to take people by surprise, and posts like that tend to secure that the game will never be used for a puzzle. So, if you see something really nice for a puzzle:

a) Check with the computer that the winning move is winning, is the only winning move, and that it either involves a sac or is difficult to find. (Or that it's the only drawing move in an otherwise lost position, of course.)

b) Email <CG> your puzzle suggestion.

<CG> does not have to accept your suggestion (most of mine were not), but that's the way to go.

Jan-23-18  ChessHigherCat: I realize that 25...Rxb3+ is best but what's the defense against 25...Bc4?

Premium Chessgames Member
  FSR: <ChessHigherCat>: 25...Bc4 is cheating. I'm guessing that you meant 34...Bc4. White's best response is 35.Rc1 Qc3 36. f6 Bxf6 37.Resigns.

This is not true. If it were, presumably if you comment with your suggested pun, CG would never use that pun for GOTD. I always comment my suggested pun, and CG has used it 125 times, which as far as I know is the record.

Jan-23-18  ChessHigherCat: <FSR> Thanks for correcting me, I did mean 34...Bc4 (I don't how I do that), but white's rook is already on c1. Do you mean 35. Rd1 Qc3 etc.?
Jan-23-18
Premium Chessgames Member
  Fusilli: <FSR> But I am not talking about puns. Puns are not a dime a dozen, I suspect, like puzzles can be. Maybe <CG> does not want to surprise with puns.

Instead, find examples of kibitzes suggesting puzzles with subsequent use of those suggestions and I would consider myself refuted. But mind you, for every one you find (if any) I may find many more examples of spoiled puzzles. :)

  Fusilli: <FSR> Also, when I suggested Guimard vs Euwe, 1946 for a puzzle, <CG> emailed back: "Thank you, we plan on using it soon. Please don't post discussion on that page for the next few days as we prefer the puzzles to be total surprises."
Jan-23-18  ChessHigherCat: Speaking of puns: <"Gligoric got Hort"> but the purists will say that it should be pronounced "gort" in Ruthenian or whatever.

  FSR: <ChessHigherCat> You got me. Here I make fun of you for a notation error, then I go and make one myself. Oops.
Jan-23-18
Premium Chessgames Member
  FSR: <Fusilli> Interesting. I assumed that was just your surmise, rather than "official" CG policy. Odd that they haven't declared it more publicly than in an e-mail to you.

  al wazir: I still think 34...Bd3 wins. Can someone tell me what, if anything, is wrong with my analysis?
Jan-23-18
Premium Chessgames Member
  Fusilli: <FSR> Maybe it's because there is no scarcity of puzzles. If kibitzers burn some, there's always countless more.
Jan-23-18

  Fusilli: <al wazir> There's probably nothing wrong with your analysis, but this puzzle was about finding the most forcing move, the one that leads to mate. Otherwise, frankly, anything wins. Even the ridiculous Kh8 wins! Because the Rxb3 threat is so big that the computer says the best white can do is Qg3 and the evaluation is -11.
