Jan-16-07  laskereshevsky: HELLO
I saw RH1+ in 2/3 seconds, after
didnt see any diff. between NF4+ and NE3+.....

at a second glange ( 15/20 seconds) finally saw the defens F3...

nice but well now tactic leit-motiv.

Jan-16-07  MathijsJanssen: I really like the mate with 41.Ne3# ( or 41.Nf4#), if white doesn't take the rook.
Jan-16-07  DanRoss53: I thought 40... ♘f6 41. e8♕+ ♖xe8 was the answer. It also seems to work, but nowhere near as effectively.
Jan-16-07  mckmck: I got it with in 30 secs.
Jan-16-07  Chess Prodigy: Alright...here's my analysis...and I didn't use fritz

1) Rh1+ Kxh1 Ne3+! f3 Qxf3 (since the knight blocks) King moves Qg2# 2) Rh1+ Kxh1 Ne3+! Qd5+ Nxd5...and that's a wrap
3) Rh1+ Kxh1 Ne3+ King moves Qg2#

so f3 results in mate anyways...

Jan-16-07  Ashram64: another sub-tuesday material :)
it's been an easy week
Jan-16-07  blair45: goldfarbdj <<I thought the answer was going to be 40. ... Nf4>>. Me too.
Jan-16-07  ppm: I think 40...Nf4 works too.
Jan-16-07  vibes43: <Strongest Force: It takes a couple of minutes to see that Ne3 is the only move after Rh1+ so as to answer white's f3 with Qxf3+ followed by mate.> I knew 40. ..Rh1+ was the solution but assumed 41. ..Nf4 without a lot of thought. I tend to overlook those stinking pawns. Thanks for pointing it out. Good puzzle - better than yesterday.
Jan-16-07  vibes43: <ppm: I think 40...Nf4 works too.> What line do you follow if white promotes 41. e8 to Q+
Jan-16-07  chessdummy123: got it in 10 seconds
Jan-16-07  mig55: <those stinking pawns> The pawns are the most important pieces ....Once moved they cannot go back..Read Steinitz...

  kevin86: I picked this one up instantly. I also saw that trying to interchange 41...♘f4 instead of ♘e3 results in 42 e3 stopping the mating threat. Of course,the text move will force a mate at g2 by the queen.

The mating strategy is another variation of the Reti-Tartokower theme. First move sac the rook or queen to divert the king into a dangerous square. Second move: create a discovery or double check. Third move: execute the mate. In R-T the focus square is the square the rook is sac-ed. In this case the focus square is g2-from which a mate can be delivered.

Jan-16-07  YouRang: I'm glad that I took a 2nd look at this, because at first I thought the immediate 40...Nf4 would do it. But then 41. e8=Q+ spoils things for black.

On the 2nd try, I found 40...Rh1+ 41. Kxh1, setting up the discovered check: 41...Ne3+, bringing about 42. Qd5 Nxd5 .

Jan-16-07  ppm: <vibes43: <ppm: I think 40...Nf4 works too.> What line do you follow if white promotes 41. e8 to Q+>

Sorry, missed this in a hurry...

Jan-16-07  Fisheremon: <Marco65: <Fisheremon> 37...Rh1+ 38.Kxh1 Ne3+ 39.f3 Nxd1 40.Rxd1 Qxf3+ 41.Kh2 Qe2+ 42.Kh3 g4+?! 43.Kh4 Qh2+ (the only check) 44.Kg5 (no more checks)> 43...Kf6! and mate's inevitable.
Jan-16-07  Stonewaller2: one last fine point is refusing the sac also dooms Black after 41. ♔g2 ♘e3, double check and mate!
Jan-16-07  DeepThought: After 42.Qd5+, Black has a whole lot more work...
Jan-16-07  suenteus po 147: <DeepThought> There's not that much work: 42.Qd5+ Nxd5; and if 43.e8/Q+ then 43...Qxe8, or if 43.Rxd5 Qxd5+ 44.Kg1 Kxe7 also wins.
Jan-16-07  Themofro: Nothing to it.

  LIFE Master AJ: Nice puzzle ... good one for a Monday.

The moral of the story? Never underestimate the power of a discovered check.

Jan-16-07  Shams: <The moral of the story? Never underestimate the power of a discovered check.> as morals go, this one should go back in the box. Chess players are famous for OVER-estimating the power of discovered checks.

Jan-16-07  LaSmitedCrab: uhh...im sure velimerovic saw this, or at least kicked himself when he saw the move. Instant spot.
Jan-16-07  BishopofBlunder: Me so stupid! I failed to solve due to lack of observation. I didn't notice the "Black to move" written above the puzzle. But Qxh8 seems to win for white.
Jan-19-07  TheSlid: <BishopofBlunder> Hee. hee, so too can I play. Nice one : )
