Jun-09-05  martinshortsays: What was the idea behind 35.f6 ? thanks in advance.
Jun-09-05  Akavall: Defending h7 pawn with the rook.
Jun-09-05  Akavall: Obviously it didn't help :)
Jun-09-05  Jatayu: Easiest Thursday I can remember. What makes it easy it that white must check, otherwise lots of trouble from the black queen.

  An Englishman: Good Evening: Easy, but still a rather curious combination--the Black Rook is overloaded, defending both the Pawn h7 and the square c8.

  WannaBe: Oh my god, I got one! I got one!! Woo.. Woo!! (I am so pathetic... This is the first one I've gotten since... Noah was taking 2 of each on board.)
Jun-09-05  Jimzovich: I really enjoyed this problem. It was an old school mate like the "1001 mates" by Reinfeld. I like it!!
Jun-09-05  Timos: Could Black have saved the game by <35...♕d2+ 36.♗g2 f6>? With the White Bishop gone from d5 to block the check from Black Queen...?
Jun-09-05  chesswonders: Nice one! If 36. ♕xd7 ♕d2+ 37. ♗g2 ♕xf4+ 38. ♔h1 ♕c1+ 39. ♔h2 ♗e5#
Jun-09-05  Saruman: <chesswonders>, it's not mate since white can play 40.Rxe5.
Jun-09-05  jamesmaskell: I got it too. Nice, rather pretty.
Jun-09-05  Autoreparaturwerkbau: <Saruman> So what's the trouble for white with 36.Qd7 then - if there is any trouble?

  Sneaky: <Timos> Interesting point, and I think you are 100% right. The rook on d7 is not really en prise due to the mating attack that chesswonders outlined.
Jun-09-05  jahhaj: First part of this is figuring out why it isn't the easiest chessgames puzzle ever. 36. ♕xd7 fails to 36... ♕d2+ 37 ♗g2? ♗g1+ winning the queen. After that it is rather easy.
Jun-09-05  prinsallan: Pretty easy today considering its thursday.
Jun-09-05  crafty: 36. ♕xd7 ♕d2+ 37. ♗g2 ♕xf4+ 38. ♔h1 ♕c1+ 39. ♔h2 ♗g1+ 40. ♔h1 ♗f2+ 41. ♕d1 ♕xd1+ 42. ♗f1 ♕xf1+ 43. ♔h2 ♕g1#   (eval -Mat08; depth 13 ply; 10M nodes)

  Sneaky: Thanks crafty.
Jun-09-05  jahhaj: In <crafty's> line, if 40 ♔g3 then 40 ... ♕e3+ with mate to follow shortly, I think.
Jun-09-05  prinsallan: <Sneaky> I need you over here man: Bird vs J Mason, 1876
Jun-09-05  jahhaj: Now that I've checked it, in <crafty's> line if 40. ♔g3 then 41... ♕e1+ 41. ♔f4 ♕e3+ 42. ♔f5 ♕e5#. Also 39 ♕g1+ is an alternative winning line.

I think it's pretty surprising that a ♕ and ♗ can mate in a position like this. It wasn't something I was looking for when I first looked at this puzzle.

Jun-09-05  billcrutcher: <Timos> Fritz thinks you are correct. After 35. ... Qd2+ it will devolve into a perpetual check.

Analysis by Fritz 8:

1. = (0.00): 35...Qd2+ 36.Bg2 f6 37.g5 Qe1 38.h4 Qg1+ 39.Kg3 Qf2+ 40.Kh2 Qg1+

Jun-09-05  cjhasbrouck: I've been doing these puzzles for quite a long time, and I think this may be my favorite one.
Jun-09-05  black knight c6: Just like to post i saw the White mate and Black mate (after ♕x♖). Thought i did quite well on that one, because how many people actually saw the black mate to the end? you could probably compose two problems out of this position somehow for black and white.
Jun-09-05  The beginner: Pretty easy for thursday :)

The first move has to be a check, if not white can easy get into a lot of troubles, if he allows black to play Qd2+

36 Qxf5+ obviusly loses to ..Bxf5
So there is realy no other move but

36 Rxh7+ ..Rxh7 (forced)
Where white can follow up with the mating combination after

37 Qc8+ ..Kg7 (forced)
38 Qg8+ ..Kh6(forced)
39 g5+ mate in 1 after
39 ..fxg5
40 Qxg5 mate.

Or 39 ..Kh5
40 Qxh7 mate.

  Richard Taylor: I got this very quickly after ai saw that 36. Rh2 + Rh2 37. Qf3 wwan'y mate! if it was why not juxt 35. Qxf3 - that hallucination over I found all the moves -it is a forced mate in all variations.

<Timos> is right 35. .. Qd2+ is very strong. 35. Qd2+ Bg2 36. f6 if now Qxd7? 37. Bg1+ !
