  Knight13: Yes! 24. Bxh7+! I got it right! It's a sample problem. But who would put a puzzle with "white to move" and black wins? Not fair!

  tpstar: Add me to the Snare List. You clever fellows are just getting us prepared for Trick or Treat, right?!
Oct-17-04   catfriend: I admit, I was snared as well:)
Oct-17-04   Chesspatch: Ahhhh, the humiliation of being tricked!!!!! My pride prohibits me from showing my face here for the next two days.... not.
Oct-17-04   Calchexas: That's mean. I saw 24.Qh5 and decided that it worked. I DID NOT look at 24.Bxh7+ to decide if it would work. The final score sorta surprised me.

  kevin86: So this puzzle is a lesson on what NOT to do,rather than what TO DO.

I picture this type of puzzle in police academies,fire academies,etc. In these situations,people perform lots of duties-but the wrong action-rather than inaction-is what causes loss of many lives.

Oct-17-04   ruylopez900: Hmm, I preferred Bxe5 first, though I guess I'm wrong since the whole sacrificial idea is wrong :)
Oct-17-04   white pawn: I thought 24.Bxh7? too. Good job Chessgames! You fooled me. However, I'm sure if the board were set up like that at my local chess spot, and white played 24.Bxh7, it would have won, so atleast I can have that.
Oct-17-04   Zaius: Analysis by Deep Fritz 8:

1. ± (0.85): 24.Rf2 Ng6 25.Bxg6 hxg6 26.Qf3 Rf8 27.Qh3 Nc5 28.Nxc5 Qxc5 29.Re4 Rfe8 30.Qe3 Qc7 31.Re2

2. ± (0.77): 24.Qh5 g6 25.Qh3 f6 26.Nd4 Nc5 27.Ne6 Qd7 28.gxf6 Bxf6 29.Rb4 Rb8

3. ± (0.60): 24.Rb4 Ng6 25.Qf3 Bf8 26.Be3 Nde5 27.Qe2 Rb8 28.Bf5 Qe7 29.Qf2 Qc7

(Depth: 14 ply, 455M nodes.)

Oct-17-04   Zaius: And I fell victim to the 24. Bxh7? siren as well, by the way.
Oct-17-04   ricardolopez: <Zaius> In your variation 1: 24.Rf2 Ng6, what about 25. Qh5? Cases of: a. 25...N(d)e5, 26. Nd4
b. 25...Bf8, 26. Bg3.
Well, but wathever were the best moves of theses, I don't see why W is lost. I'm sure with 24. Bxh7 he is, so this might be the worst move not the best. I can't see where I´m wrong.

  JohnBoy: First of all, I got suckered in too. By way of pathetic justification, I spent about 30 secs on it and decided that soem variation of Be5, Qh5 and Bh7 won. But didn't see through to the end and walked into a poorly executed attack.

Second of all, I love the twist. Chessgames ought to throw more of these at our complacent asses.

Thirdly, is there a repository of puzzle games that I can look at? Like the "Game of the Day" repository?

Oct-18-04   likestofork: <Hidden Skillz> 32. Kf2 Qxc2+ 33. Kxe1? (white has better moves, but better is a relative term. White has moves that don't lead directly to mate.) Re8+ 34. Kf1 Qe2+ 35. Kg1 Qxg4+ 36. Kf1 Qf3+ 37. Kg1 Re1++. <Chessgames.com> The hook is still in my mouth. I'm gonna have to get a pair of pliers to remove it; I'm probably in need of some morphine, too. The tragic part was that I saw the sign of a 'trap', specifically the 'What is White's best move?', and made the observation, Oh, something different (yeah, when you break it down, that's essentially what you always ask. Still, you asked it differently, and that should have been a clue.). Anyway, I then proceeded right into Brer Rabbit mode. I really liked it.

  patzer2: Expanding on Crafty's line 32. Kf2 Qxc2+ 33. Nd2 [33. Kxe1? Kf1 34. Qe2+ 35. Kg1 Qxg4+ ] 33...Qf5+ 34. Qf4 Re5 35. Qxf5 Rxf5+ 36. Nf3 Rxd5 37. Rb4 Rd7 is a decisive endgame win with an exchange up and two extra pawns.
Aug-09-05   Whitehat1963: I would think that Csom would always be better than Nunn. Too easy!

  ruinme: Wasn't Nunn winning until he got all archaic and didn't take the d6 pawn around move 21 or at least bust through with e5?
Aug-22-09   TheBish: 27...Nf3+! Nice move. Of course, not 27...Ng6?? 28. Qh7+ Kf8 29. Qh8+!

  kevin86: What a finish! White is about to bring the fatal blow,when the hatchet falls-the OTHER way.
Aug-22-09   offramp: Whenever I see an early ...Qb6 from black I shout out "YES!! I am back!" But when I see white fail to gambit his b2 pawn I yawn.
