  Check It Out: 26.Qf4 threatens the knight fork on e6. If 26...Qxf4 27.Re8+ Rxe8 28.Nd7#
Jul-08-09  YouRang: Bah. I hastily miscalculated and thought that I found the solution with 26.Nd7+?

Monkey see check, monkey give check.

Monkey lose. :-(

Jul-08-09  parisattack: First 2-Star I've missed for awhile. Saw 26. Qf4 but it looked some involved and assumed a 2-star meant there was a quicker hit...
Jul-08-09  randomsac: I thought of Nxb7 followed by Qc5+. That line seems to get pretty ugly. I have to admit that the mate is better, but I wonder if my line would give me a winning advantage.
Jul-08-09  MostlyAverageJoe: Very curious. This puzzle seems to be much more difficult for humans than my engine-based evaluation would indicate (which classified it as "between Tue/Wed" difficulty, leaning towards a difficult Tue).

Oh, well, this one is an outlier.

Jul-08-09  beenthere240: <arcturus> I like your 27. Nxb7 Rdc8 but after 28 Nd6 what about simply Qxd6? I don't see any mate.
Jul-08-09  Arcturus: Ha Ha ! You are right! When I said I was in a rush I meant it. Looks like I'll be double checking my stuffs before the next post. 8-)
Jul-08-09  beenthere240: Well, you do win an important pawn!! I went that route myself but followed it up with 28. Qc5+, which also appears to fizzle out.
Jul-08-09  beenthere240: Actually, I don't even like 27. Nxb7 any more since ... Qxb7 seems pretty good. This is more my style: search and find a losing move!
Jul-08-09  PalladiumPawn: No Good. I looked at 26. Bf5 with the intention of eyeing d7 along with activating my bishop. But, alas, this is too slow and fails after 26...Nf6 among other things.
Jul-08-09  WhiteRook48: struggling with 26 Nxe6+??

  fm avari viraf: To be candid, I didn't find the right move at a glance which normally I do. But I was finding out the candidates like 26.Bg6, Bh7, Ne6+ & then I sppotted 26.Qf4 which finishes off due to Black's back rank weakness.

  gawain: Poor Buhmann. Lest we feel too sorry for him, though, look again at a previous puzzle:

R Buhmann vs B Saeheng, 2008

Jul-08-09  scorpius: 26.Nxa6 should be 1-0 after bxa6 27.Qc5+. 26.Qf4 is better though
Jul-08-09  morfishine: Now I get it...very good for a 2-star
Jul-08-09  vulcan20: Wow did I miss it. I was so intent on getting in Ne6 I completely overlooked White's simple remove-the-defender tactic!
Jul-08-09  lzromeu: Are This a Plachutta threats example?
Sac the Queen, sac the rook and mate by Knight and other unmoved rook
Jul-08-09  JG27Pyth: There just had to be some way to get the N to e6 or d7... and after a bit of searching the Q deflection revealed itself.
Jul-08-09  jsheedy: <vulcan20> Me too! When I saw the move, I thought, How can that work? Then I played it out. Nice.

  TheDestruktor: <gropek>, in case you are still reading: to quote something, just put it between "<>"
Jul-08-09  newzild: Damn, I went for 26.Nxa6 ba 27.Qc5+ Nge7 28.Rxe7, which wins because 28...Nxe7 drops the queen. The actual game continuation is much better, of course.
Jul-08-09  TheBish: S Fedorchuk vs R Buhmann, 1999

White to play (26.?) "Medium/Easy"

I got this fairly quickly, once I saw the mating possibilty after a couple of diversions.

26. Qf4! offers a trade of queens, which Black can't accept. White threatens 27. Qxc7 as well as 27. Ne6+, winning the queen.

A) 26...Qxf4 (or 26...Qb6 or Qa5) 27. Re8+ Rxe8 28. Nd7#.

B) 26...Qd6 27. Re8+ Rxe8 28. Qxd6+ Nge7 (or Re7) 29. Nc7+ is easy.

C) 26...Qc8 27. Ne6+ Ke7 (or Kd8) 28. Nxd8+ Kxd8 (or Black loses a whole rook) 29. Qd6+ and mate next move.

D) 26...Rd6 27. Ne6+ wins the queen for a knight, since 27...Rxe6 28. Qxc7.

E) 26...Ne5 (or Rbc8) doesn't address both threats, as simply 27. Ne6+ wins the queen.

The bottom line is, Black is busted and should resign! Note that Black's g8 knight would be a much better defender on f6!

  ZUGZWANG67: Hm. I could not quite solve this one. I saw 26.Qf4 but did not realize how strong it was.
Jul-08-09  goldenbear: I'm always suprised by what causes people difficulty. I saw that Bg6 Nf6 was incorrect and then looked at Qf4. The whole thing took about 8 seconds. This is one of the puzzles I saw to the end. I always get the first move but rarely see anything to the end.
Jul-08-09  DarthStapler: I didn't get it
