Nov-12-04   Captain Scarlet: I saw the idea of rxf6 followed by g4, winning easily, very quickly. It may or may not be best but it is what I'd have played and quickly too!
Nov-12-04   Marco65: <chessgames.com> The name of the player is "Fernando", not "Fernanado". He is an Italian IM, current ELO 2465.
Nov-12-04   DWINS: <Marco65> After 31...Rfb8 white simply takes the rook with 32.Bxb8
Nov-12-04   Marco65: <Dwins> Sure! That will teach me to never challenge a line a GM is giving! After 29.Rxf6 gxf6 30.g4 Qh3 31.Qd4 checkmate seems unavoidable, e.g. 31...Rfc8 32.Bh6 Rc2 33.Ke7+ Kh8 34.Qxf6#
Nov-12-04   sourcerer: an amazingly simple line of the queen's but i saw Nxg7 winning though i could not see it thru
Nov-12-04   panigma: I would like more info than "white to play and win" from now on, such as..."white to play and win after a ridiculous combination of moves that nobody rated below 1500 will ever figure out anyway." At the very least this would save me some time.
Nov-12-04   maoam: For once I'm quite proud of the fact that I didn't get this puzzle right. I expected 29.Ne7+ Kh8 30.Rxf6 gxf6 31.Qd4 etc. as in GM Keene's line.
Nov-12-04   quartex74: Maybe 27... Qf2 28 Kh1 g5?!?!?!?!?!

X_o!!!

  benveniste: This is an odd puzzle. I found
29 Rxf6 gxf6
30 Qxd5 Kh8
31 Bh6 Qg6 (Anything else for black?)
32 Bg7+ Qxg7
33 Nxg7 (etc)...
Nov-12-04   Flyboy216: I left Crafty running overnight by accident :)

29. Rxf6 gxf6 30. g4 Qh3 31. Qd4 Bf1 32. Ne7+ Kg7 33. Bh6+ Qxh6 34. Nf5+ Kg6 35. h4 Rfe8 36. h5+ Qxh5 37. gxh5+ Kxf5 38. Qf4+ Ke6 39. Rb6+ Kd7 40. Qd6+ Kc8 41. Rc6+ Kb7 42. Qc7#

Nov-12-04   Granite: Thanks <ray keene>! I'd spent a long time evaluating Rxf6 and came to the same line you discussed and I wouldn't have trusted my evaluation enough after I saw the solution. Thankfully, I can trust yours on what I felt was the more obvious way to win.

  kevin86: A very complex problem-I saw g4 quickly-but didn't calculate the results after Qh3. I saw the blunder 29... Qg6 30 Ne7+

  TonyOliva: Someone may have looked this through... if so, I apologize. But when I analyzed this I came up with the following:

29. Ne7+ Kh8 30. RxN pxR (else White is up a Knight)31. Qd4... (Threatening 32. Qxf6#)

A. If 31. ... Qh4 (protecting f6) 32. g3 Qh5 33. Qxf6#

B. If 31. ... Kg7 32. g4 Qh4 33. Nf5+ winning the queen.

C. If 31. ...Rg8 33. Qxf6+ Rg7 34. g4 winning the queen.

Am I missing something here?

Nov-12-04   Rank Amateur: My plan was to trap the black queen on h3 and win her with the rook.

29 g4 Qhe
30 Bh6 gxh6
31 Rxf6
then I don't know what black does, but I think I've got his queen. Or maybe not, I guess he can force the exchange with Qf1 +. So I guess I gained a piece.

Nov-12-04   misguidedaggression: <benveniste:
29 Rxf6 gxf6
30 Qxd5 Kh8
31 Bh6 Qg6...>

I think Black escapes with a difficult endgame after 30...Rfd8 after 31.Nh6+ Qxh6 32.Bxh6 Rxd5 Black is only a pawn down. Though 31.Qxa5 might still keep the attack going,31...Bb7 is hard to answer.

  patzer2: <Captain Scarlet> <blyboy216> Thanks for the analysis of 29. Rxf6 gxf6 30. g4 Qh3 31. Qd4 This was my solution, but Crafty's reply 31...Bf1!? in this line surprised me and could be difficult to refute over the board.

  patzer2: Really enjoyed the 29. Nxg2!! solution to this daily puzzle. At first it appeared to be a combination to win a pawn and then win back the sacrificed piece utilizing the pin for a clear advantage. But then I realized after the wicked double attack combination with 37. Rxc8! Rxc8 38. Qg4+, White mates or wins decisive material.
Nov-12-04   aw1988: I think Rxf6... crushing threats.
Nov-12-04   aw1988: DAMNIT I got it wrong. :(
Nov-13-04   Saruman: What about 31.Rxf6!
Nov-13-04   Marco65: In Crafty's line 29.Rxf6 gxf6 30.g4 Qh3 31.Qd4 Bf1 prevents mate because of 32.Rxf1 Ra6, therefore Crafty suggests 32.Ne7+ Kg7 33.Bh6+ Qxh6 34.Nf5+. At this point, changing my mind, I turn back to my originally proposed move order:

29.g4 Qh3 30.Ne7+ Kh8 31.Rxf6 gxf6 32.Qd4 Kg7 [32...Qh4 33.g5 and then mate] 33.Bh6+! Qxh6 34.Nf5+. Here Black has to lose a tempo by moving the king to h8 before g7. At least, it can't be worse!

Nov-13-04   Dick Brain: Hey <TonyOliva>, Tony O. was one of my favorite baseball players in the days of old maybe second only to Orlando Cepeda.
Nov-17-04   Saruman: 31.Rxf6! Qxb1+ 32.Kf2 Qf1+ 33.Kg3 Qe1+ 34.Kh3 when I cant find a good move that deals with the threat;35.Bh6+ Kg8 36.Rg6++! hxg6 37.Qg7#.

This is the combo white can use when black stops checking.

Nov-17-04   Saruman: Or 32.-Qg6? 33.Bh6+ Qxh6 34.Rxh6+ f6 (Kxh6?? Qf6+ Kh5 g4#) 35.Rh5 the black pieces are scattered and lack coordination.
May-31-05   Autoreparaturwerkbau: <patzer2> You are at the wrong side of the board ... you might want to say "29.Nxg7!!" instead of g2.
