  playground player: Did anybody get all 56 moves of this puzzle? Be honest, now.
Jun-21-08  jmhobrien: I don't think anyone was expected to get the entire game...just up to and including the annotation at move 24.
Jun-21-08  Once: <playground player> <jmhobrien> I don't think that we need to get all the moves in order to consider it solved. It should be enough to find a sequence of moves that wins - even if it was not the sequence actually played.

In the starting position, either Rxe6 or Qf2 win, if properly followed up.

Jun-21-08  MaczynskiPratten: My thinking on 19 Qf2 was that it threatens Qh4+ and if Black plays Qxe5 White has 20 Rd7+ Bxd7 (if Ke8 Rd5+, if Kf8 Rxf7+) 21 Qxf7+ Kd6 22 Qxd7+ Kc5 23 Rc1+ which seems even more forcing than 20 Rxe6 - so maybe the move order does matter, 19 Qf2 gives this extra option.

  Jimfromprovidence: White could have won a rook with 26 e6!, threatening Qd7+ with mate the following move.

Black must play 26…Rd8 to avoid mate. White now plays 27 Qc7, threatening Qf7# next move. Black is forced to play 27…Rf8 to avoid mate. White now applies the clincher with 28 e7!, forking both rooks and threatening exd8Q#.

Black now must play 28…Rf1+ to avoid mate, losing a rook.

Jun-21-08  Jim Bartle: Excellent, JFP.
Jun-21-08  JG27Pyth: Gack! Too hard. (Toga II thinks Rxe6 is second best at +1.66.) Qf2 is very elegant but *sigh* I'm a long way from finding that move -- even in a puzzle, let alone OTB.
Jun-21-08  YouRang: <Jim Bartle: Excellent, JFP.>

Oh, sure. It's excellent when <JFP> says it! :-p

  Jimfromprovidence: <YouRang> I overlooked your post. I apologize. Maybe that typo you had <26.e3 is cuter> made me pass it by.
Jun-21-08  Jim Bartle: Sorry about that, Yourang.

It's like a routine from Get Smart, where Max would make a suggestion, 99 would repeat it, and the Chief would say, "Good thinking, 99."

Jun-21-08  SufferingBruin: ChessMaster found the annotated line and win very quickly.

I did not. :)

I was looking at Rxf7+, saw nothing; I knew I had to act fast but I did not see Qf2.

Jun-21-08  YouRang: In case there's any doubt, I hope y'all know my last post was in jest. :-)
Jun-21-08  Jim Bartle: Yes, but when the person "jesting" is seven feet tall...
Jun-21-08  Marmot PFL: 19.Qf2! is a quiet move, and often those are the hardest to see. Surprisingly, black has no defense to Rxe6+ with mate or decisive material gain. Also as well as white played that part of the attack, 26.e6! (instead of Qxd3) would have saved him from having to play 77 moves to win.
Jun-21-08  whiteshark: <Jesspatrick> I think that <19.Qh5! Qxe3+ 20.Kh1 Raf8 21.Bc4!! > is already resignable.

Jun-21-08  vanytchouck: the point that help me to see all the good moves (for me, it's very seldom)is the fact that the e5 pawn prevent the black king from escaping from the 7th rank. At the very first sight i was thinking about Rxe6, but there it failed because of Kxe5 wich is possible.

At last, i think the line 24. Qxg7 Re8 25. Qxh7 and then winning the "d" pawn is better because of the linked pawns "g" and "h" too strong to be stopped (you can later even trade a rook against the queen).

Jun-21-08  Lutwidge: D'oh. I thought it was Qh5, with similar ideas, but overlooked how useful Qxe3+ is in reply. However, it could still wind up in an arguably winning position for W:

19. Qh5?! Qxe3+!
20. Kh1 Raf8 (h7 must remain defended, otherwise Rxe6+ fxe6 Qh4+ g5 Qxh7+) 21. Rfd1! Rfd8 (to meet Rd7+)
22. Qh4+ f6
23. Rxe6+! Kxe6
24. Qg4+! Kxe5 (other moves lead to a quick mate)
25. Bd7! Rxd7 (otherwise Qe6+ or Qf5++)
26. Qxd7 Qc5

And white is probably still winning due to Black's exposed King. For instance:

27. Qxg7 Rc8
28. Rf1 Rc6 Qxh7

And Black's game hangs by a thread.

Jun-21-08  Lutwidge: Oh, Jesspatrick more or less already mentioned all this. And, yeah, 21. Bc4 wins rather convincingly for White there.
Jun-21-08  Granny O Doul: This was one quiz where the key move is easier to find if you think of it as just a position rather than as a quiz.

Though the opening is listed as an "anti-Nimzo", it was actually more of an anti-Benoni.

Jun-22-08  patzer2: For the Saturday June 21, 2008 puzzle, White offers up his Bishop as a decoy sacrifice with the surprising 19. Qf2!!

See <YouRanq> and <Jimfromprovidence>'s post on the neat double attack follow-up with 26. e6!

Jan-05-09  WhiteRook48: ....Rg4?? why not Ra3+?
Jan-05-09  Granny O Doul: <WhiteRook48> If 76... Ra3+ 77 Kc2, and either ...Rc3+ 78 Qc3! or ...Ra2+ 79 Kb1 and Q takes the rook if it checks again.
Oct-05-12  wildrookie: Couldn'tBlack have saved a draw in this game by constantly chasing the White King around the board with never-ending checks?
Oct-05-12  woodbeast: A stalemate plan doesn't work here. What can Black do when the White King gets to g6?
Jul-14-15  DanielHoseano: Is'nt this checkmate??
