  YouRang: How disappointing. For the life of me, I couldn't figure out how black would answer 32. Kh1, so I finally and anxiously looked at the game to discover black's "miracle move", only to find that it didn't exist.

Maybe this should be a "find white's blunder" puzzle. Answer: 32. Kf1.

  chessgames.com: This problem was originally stated as "32...?" with the intention of finding 32...Rg1+!! as the winning move. At the last minute we switched it to move 31 due to an erroneous computer assessment.
Aug-04-05  sleepkid: ...ooh, a quick retraction of a post by chessgames.com stops me from shooting down the erroneous analysis they had posted in defense of today's puzzle. ;-)

flawed though this puzzle is, it does contain a valuable lesson: don't resign while you still have a shred of an attacking chance.

many people would just look at this position and simply say "there's nothing that black can do." I'm not sure this is what Lasker had in mind when he said "have faith in the resources of difficult positions" but it does add some truth to the maxim.

Aug-04-05  alexandrovm: Black need a fast reaction, or will be mated in one. 31. Rxg2+ if white takes then Kxg2 32. Rg8+ if white goes to h1 is mate in two with the queen Qd5+ and Qxf3#; if Kf1 then Bh3+ Ke2 etc. Seems black can mate white's king. He may even have to use the f4 pawn.
Aug-04-05  alexandrovm: I would say that I could get to hate the guy who got away from my mating net like in this game. 31. Bb7, perhaps that could have been the winning move for white? Kxb7 is forced, and Nxa5+ could have followed?
Aug-04-05  sharpnova: <alexandrovm> you obviously have not been reading this thread. if white moves to h1, then he wins the game. black loses. Qd5+ is impossible since the rook is on g2 blocking such a check.
Aug-04-05  teme: This puzzel was hard because of all the calculations. It took me 5 minutes to get the whole thing.

  chessgames.com: Well, the day is half over, but we'll restore today's problem to the way that it was originally intended, the idea being to find Black's 32nd move.

  WannaBe: Since we are starting over, can I be first?! :-) LOL. I got it in 0.00000000000023 sec...
Aug-04-05  The beginner: Why not 11 Qxb7 ?

Im guising it leaves white to far behind in development. Or is there another reason which i can not see, afterall it would leave white up 2 pawns.

  crafty: 32. ♔h1 ♖g1+ 33. ♖xg1 ♗d5+ 34. ♖g2 ♗xc6 35. ♕xc6+   (eval 6.15; depth 13 ply; 1500M nodes)
Aug-04-05  chessic eric: Well, I'm adding my two cents even after crafty (he found my move 34.Bxc6 but I swear I analyzed it independently.) I gotta say in the "32.Kf1, black to play and win" puzzle I like the line 35...,Re8+ instead of f3+ since it forces mate sooner (36.Kf3,Qd5+ 37.Kxf4,Qg5+ 38.Kf3,Qg4# - i think <Richard Taylor> also posted this line earlier).

If 32.Kh1 (notice how good a counterintuitive move can be if calculated!!) then: 32...,Rg1+
33.Rxg1,Bd5+
34.Rg2,Bxc6 and white has to recapture carefully, since 35.Rxc6?,Qd1+ and mate in three. But 35.Qxc6+ forces the exchange of queens and is a win for white.

Aug-04-05  OneBadDog: Was beating White so badly the Christian thing to do? White really had a cow after this game.

  WannaBe: <OneBadDog> Boo! Boo! Hiss! Hiss! Mooooooo.... :-)
Aug-04-05  OneBadDog: Black gets coal in his stockings for winning this game.
Aug-04-05  ajile: The puzzle is not an error because it STARTS after Kf1, not at the previous move. Of course Black made an error by playing Kf1 vs Kh1 but that isn't where the puzzle begins from.
Aug-04-05  sleepkid: ajile: you're a latecomer to this party. chessgames changed the diagram to make the puzzle correct. It was incorrect before.

  offramp: Black's 32...Rg1+! is a demolition of pawn structure combination or decisive obstruction or interference move, setting up 32...Bxd5 and 36...Bg7 for a winning attack on White's weakened castled position, utilizing the pin tactic as a deflection to force a won king and pawn ending.
Aug-04-05  erikcu: Chessgames.com could make this a 32. white to play and win puzzle someday in the future... Would that be a puzzle of Thursday calliber?

I am sure since we all know the bust, it looks as easy as Monday, but as someone pointed out, trapping your king in the corner is a counter intuitive escape. Claus Hoeg Von Holstein Rathlau certainly missed it.

In about 6 months when I have completely forgotten this game, Chessgames.com could post the puzzle as a White to win... I wonder if I will recollect the game, or walk into the same mistake as the game was played.

Aug-04-05  OneBadDog: <Claus Hoeg Von Holstein Rathlau certainly missed it.> Looks like he had to suffer udder failure in this game.
Aug-04-05  ajile: how do you quote someone?
Aug-04-05  rexeterna: <ajile>(<--see? perfect example:) If you want to quote someone, just enclose whatever it is they said in <these brackets,> and then it highlights it.

  Gypsy: < I am sure since we all know the bust, it looks as easy as Monday, but as someone pointed out, trapping your king in the corner is a counter intuitive escape. Claus Hoeg Von Holstein Rathlau certainly missed it.> Well, Crafty also missed it at first. The bust is not easy to find at all! It depends on some beautiful defensive resources. Consider the following: 32.Kh1! Rg1+!? 33.Rxg1 Qd4+!? 34.Rg2 Qd1+ 35.Bf1!! ... where White rook saves the day via a nifty x-ray. Instead, the 'natural' continuation 35.Rxd1? would still drop the game to 35...Rxd1+ 36.Rg1 Bd4+ 37.f3 Bxf3#.
Aug-05-05  OneBadDog: Maybe White lost due to Mad Cow Disease.

  patzer2: Looks like I got caught up in the excitment of seeing a demolition combination this morning, and didn't check to see that White's first reply 32. Kh1! could bust it.

Still 31...Rxg2! was apparently Blacki's only chance to complicate the position and create winning chances, which he did with a neat swindle after 32. Kf1? Rxg1+!

Such possibilities only increase my fascination with and appreciation for the power of these demolition of pawn structure combinations.
