Jul2816   gofer: I "found" 16 Bc5, but just like <Once> and Fritz I was concerned that black would simply exchange off its queen for R+B+2P. I think, given the outcome black was wrong not to take that route, but it obviously doesn't necessarily mean that Bc5 is "wrong", just not as perfect as we might want... 

Jul2816
  scormus: <Once> I went through the same thought processes with 16 Bc5, thinking ... Qf4 17 Qxd5 and 18 Re8 after B moves the Q. But I also wondered if B could cut his losses but discounted that possibility on the basis that it was a puzzle and I expected a clear cut outcome. I checked with Rybka which gave the same result as your Fritz. In fact W would have quite a lot of work to win this against good play. It also gave 16 Bd2 as the best move from the start position. It seems that there is an emotional element in the way players and puzzle solvers alike view positions. But not the silicon ;) 

Jul2816   jd4chess: Well stockfish thinks Bc5 is a weak move that throws away most of white's advantage, preferring Bd2. I tried Bf4 and Qd5+ but Nd6 holds and black's a piece up. 

Jul2816   alshatranji: So after 18. Qc5, Black simply capture the bishop with the knight. An unfortunate oversight. 

Jul2816
  whiteshark: In the lang run luck is given only to the efficient. 

Jul2816   diagonalley: yep... i also thought that black might well accept B+R for his queen 

Jul2816
  FSR: This puzzle is busted. Like others, I rejected 16.Bc5 because of 16...Qxc5! 

Jul2816   BOSTER: My opinion that the best is 16.Bf4. 

Jul2816   The Kings Domain: Missed this one. I came up with 16) Bf4 and it's mate should black get greedy. Nice and clever mating combo by white. I wish I could be as complimentary with the pun. 

Jul2816   WorstPlayerEver: Bit of a curiosity...
16. Bd2 Be7 17. Qa4 a6 18. Bf4 Qb6 19. Bc7 Qc7 20. Rc7 Kc7 21. Rc1 Kb8 22. Bd3 Nd6 23. Qd7 Rc8 24. Rc8 Nc8 Black is in Zugzwang and has no good moves left. For instance: 25. g3 h6 26. Kg2 a5 27. Qe8 Bf6 28. Qf7 Not bad for a Thursday puzzle ;) 

Jul2816   eblunt: <scormus It seems that there is an emotional element in the way players and puzzle solvers alike view positions. But not the silicon > The silicon analyses the position at face value, whereas all of us here are looking for the blockbuster move that we are led to believe exists. 

Jul2816
  scormus: <eblunt> ..... or that we lead ourselves to believe exists! 

Jul2816
  steinitzfan: Somewhere along the line we started calling asymmetric exchanges involving the queen "sacrifices." Why was that? Can we just not deal with the idea of doing without the queen? If nothing else you can expect the computer to take the math literally when a programmer sets up a table of values. 

Jul2816
  kevin86: White needed to chase the black queen away so mate can be given a few moves later. 

Jul2816   morfishine: Optical Confusion & an illogical if not outright dumb playonword 

Jul2816   posoo: dis is NOT a dum pun Morfudlian. FOULDS did not LOOSE and dat is NOT NESSARY for da pon to work. Da game is MEARLY showing u wat happens when FOLDS is UNDERPRESSURE. NOT PATHETIC.
Also wat hapuned to ur starrs?

Jul2816   RandomVisitor: After 15...Nf5, 16.Bd2 is apparently winning, while 16.Bc5 only invites black to play on with 16...Qxc5 click for larger viewKomodo1064bit:

  agb2002: White has the bishop pair for a bishop, a knight and two pawns. White would deliver mate if the bishop on e3 and the pawn on e6 disappeared. Therefore, 16.Bc5: A) 16... Qb8 17.Qxd5+
A.1) 17... exd5 18.Bb6+ and 19.Re8#.
A.2) 17... Bd6 18.Rxe6 fxe6 (due to 19.B(R)xd6) 19.Qxe6 A.2.a) 19... Qc8 20.Bb6+ Bc7 (20... axb6 21.Rxc8+ Rxc8 22.Qd7#) 21.Bxc7+ Qxc7 22.Rxc7 Kxc7 23.Qxf5 +  [Q+B+P vs 2R]. A.2.b) 19... Qc7 20.Qxf5
A.2.b.i) 20... Bxc5 21.Rxc5 wins (21... Qe7 22.Qd5+ and mate next). A.2.b.ii) 20... Rf8 21.Qd5 looks winning. For example, 21... Rf6 22.Rd1 Ke7 23.Re1+ Kf8 (23... Kd8 24.Re8#) 24.Bc4 Qf7 (24... Rf7 25.Bxd6+ wins) 25.Qxd6+ wins. A.3) 17... Nd6 18.Bxd6
A.3.a) 18... exd5 19.Re8#.
A.3.b) 18... Bxd6 19.Qe7+ f6 (19... Be7 20.Red1+ Qd6 21.Rxd6#) 20.Qxg7 Rf8 21.Red1+ wins (21... Bd6 22.Qd7#). A.3.c) 18... Qd6 19.Qf3 looks winning. For example 19... Qb6 (19... Qe7 20.Red1+ wins) 20.Qxf7 Qxb5 (20... Be7 21.Rxe6 wins) 21.Red1+ Qd5 (21... Qd7 22.Rxd7+ Kxd7 23.Rd1+ wins) 22.Rxd5+ exd5 23.Qxd5+ etc. B) 16... Qf4 17.Qxd5+ looks similar to A.

Jul2916   Moszkowski012273: 17.g3... is quite incorrect. The immediate 17.Qxd5+... is much better.

Jul3016   Gerry84: Sorry, but how is this game not titled FouldsLang, Resign?

FOR ALL ACUINTONS
be forgut
AND never BROTTUMINE!
or sompon else. 

Mar2817   clement41: Perhaps 18...Bd6 is a tad more testing, although not only 19 Qxb7 wins, but also the pretty 19 Bxd6 ed 20 Bc7+ Kc8 21 Bf4+ (21 Bb6+ Kb8 22 Bc7+ if white needs to repeat) followed by 22 Bxg5 is In the game line, 19 Re8+?? would be a catastrophe as after 19...Kc7 there's no decisive discovered check and black is better
