|Jun-15-06|| ||Marco65: <euripides> Oops, I had just noticed that I missed 32.c4 when I saw your post. I can't find anything better than:|
(after 27.Rxf7 Qh1+ 28.Kf2 Rxf7+ 29.Ke3 Qh6+ 30.Kd4 Rf5 31.c5! d5!)
d) 32.c4! Qf6+ 33.Ke3 d4+ 34.Kd2 Qg5+ 35.Kd1 (maybe also Ke1 works) Rf1+ 36.Re1 Qg4+ 37.Qe2
Maybe 30...Rf5 was not that good...

I am trying to give up coffee and have done without for two weeks now. As well as being in a headachy foul temper most of the time, I was unable to solve a single puzzle all that time.
This elevenses I gave in to my craving and ..... solved this instantly. Including RV's improvement 24....Rxf2
|Jun-15-06|| ||KingG: I also thought the solution was 22...Nxg3 23.hxg3 Qxg3+ 24.Kf1 Qh2! 25.Rxf7 Qh1+ 26.Kf2 Rxf7+ , but i didn't see Black's best moves after that. In fact, it's mate in 9. Black mates by pushing White's king towards the Black pawns, and then using them to finish the mate. This is the longest line:|
27.Ke3 Qh6+ 28.Kd4 Qf6+ 29.Kd5 Qf5+ 30.Kc6 Qd7+ 31.Kd5 c6+ 32.Kd4 Qg4+ 33.Re4 Qg1+ 34.Qf2 Qxf2+ 35.Re3 Rf4#
However, Black had another way of winning, that was possibly simpler win:
27.Ke3 Rf1 28.Nb3 Qf3+ 29.Kd2 Qf4+ 30.Re3 Rf2+ 31.Kd1 Rxc2
|Jun-15-06|| ||RandomVisitor: Here's one way to win if White plays 25. Rxf7:
25. Rxf7 Qh1+ 26. Kf2 Rxf7+ 27. Ke3 Qh6+ 28. Kd4 Qf6+ 29. Kd5 Qf5+ 30. Kc6 Qc5+ 31. Kb7 c6+ 32. Kc8 (!) Qf5+ 33. Kb8 Qd7 34. Re7 Rf8+ 35. Re8 Rxe8#
|Jun-15-06|| ||Tariqov: I Gave up on this puzzle, i only saw the Qh2 line that most people saw but couldn't find an answer to ke3,only thought of Qf3+ did not see Qh6+!.hard puzzle,i think Black trusted his intuition ,so many lines.|
|Jun-15-06|| ||crptone: Beautiful problem!! I think this problem was fitting for a Thursday. |
I think that if you did not see the series of checks that would pick knight back up or the exchange, then you did not solve the problem.
Its quite clear that the knight is unprotected after the queen captures the rook. (if king captures, an obvious queen skewer results)
|Jun-15-06|| ||Tariqov: <crptone>yup!and if you did not see the variation with Rxf7,you did not solve it.Right up to mate.is this really fitting??i think it's a sunday or saturday puzzle there are so much variations to calculate after the Qh6+ which will come to a mate after Kd4,and if you do not know what i'm talking about... i don't think you solve it.|
|Jun-15-06|| ||Tariqov: 'you' in my post above= anybody reading it|
|Jun-15-06|| ||YouRang: Hmmm. I figured 22...Nxg3 had to be the solution, but there were so many variation that could follow, and it wasn't clear that I could force a win.|
As it turned out, the point of the move was to pick up a couple of pawns, and simplify. Obviously, a winning tactic, but not obvious for me to see how it worked. :-(
|Jun-15-06|| ||kevin86: The finishing zig-zags by the black queen were quite whimsical. White could do nothing but give the piece back,and lose the ending-being two pawns to the bad.|
|Jun-15-06|| ||jajaja: if white's 27.Rxf7 transposes to the 24..Qh2 line then the text move 24..Qh4 was unnecessary in my opinion. and black should have played 24..Qh2 if this is the case.|
|Jun-15-06|| ||Halldor: <monad>: Probably because of the 'vegetable alkaloid stimulant' I only got the first two moves right and then went for my own line with a splendid finish in the style of a Tuesday puzzle... I will definitely have to adopt your method to survive longer in the week.|
|Jun-15-06|| ||dakgootje: calcuted many variations including the played one (didnt consider it strong enough as others, as it was much slower) and finally just became aware that most variations, if black didnt play too stupid, wuold win, and the sac was sound enough to play|
|Jun-15-06|| ||Nomen Nescio: Not very difficult. This looks like countless games I've played on yahoo.|
|Jun-15-06|| ||Tariqov: <nomen>did you see Qh6+ ??in one of the lines??just curious.I really don't think this is an easy puzzle,sure, anybody can find the first few moves but did you calculate 25Rxf7Qh1+ 26.Kf2Rxf7+ 27.ke3 Qh6+ right up to mate??or KingG's 27..Rf1 winning line??if you didn't ,you didn't solve it.|
|Jun-15-06|| ||Paladin88doug: I must say that I had trouble with this puzzle. I knew that the knight was the right piece to move by intuition, so I looked at the possibilities behind Nxg3, Nh4, Ne3 and Nd4. Nd4 seems useless. Ne3 had a little bit of a similar line I saw that has interesting figures, except the king still has shelter... Ne3 23. Rxe3 (of course this was busted in my mind after Qd2! when Black loses his battery) Rxf2 24. Rxf2 Rxf2 25. Qxf2 Qxc1...this position has a similarity to the one in the puzzle, except that the king still has shelter, so it seems insufficient. Nh4 seemed interesting, the pin had reason, and then Nf3+ leading up to 25.Rxf3 Rxf3 and White must act fast, perhaps Rf2 to try to establish equality, but there are many lines that can come from here and it would take lots of lines. |
I finally felt that Nxg3 was the move, but I can't say sure enough to gain credit for this puzzle. Here was my line I saw..
Nxg3 23. hxg3 Qxg3+ and from here I saw different possibilities... I guess if I had a stronger endgame feel, I would have chosen this line... Congrats to all who saw it!
|Jun-15-06|| ||jackmandoo: That sure was a neat combo. I wish I could do something like that in an actual game. You know what else I wish I could do? Talk to girls.|
|Jun-16-06|| ||Marmot PFL: 22...Nxg3 looked promising but very complicated, so I went with 22..Ne3 23.Qd4 Rxf2 24.Rxf2 Rxf2 25.Kxf2 Ng4+ 26.Ke1 Qxd2+ 27.Kxd2 Nxh2. I know my limitations so I'll take a safe material edge over a sharp attack, especially if time is running short.|
|Jun-16-06|| ||Rocafella: <jackmandoo> Talking to girls is easy, it's getting them to talk back that's the problem.|
|Jun-16-06|| ||technical draw: <Rocafella> I talk to girls and they talk back to me. They usually say "leave me alone or I'll call the cops".|
|Jun-16-06|| ||Rocafella: <techincal draw> Some people got it, some don't. You definitely haven't!|
|Jun-16-06|| ||technical draw: <Rocafella> You are right. That's why I said forget good looks, money talks, BS walks...!|
|Jun-16-06|| ||Rocafella: Hehe, my initials are B.S, I get enough of it ;)|
|Jun-16-06|| ||jackmandoo: Hmmmm, maybe this isnt right the forum to find support or good ideas for my dilemma.|
|Jun-21-06|| ||patzer2: Black's demolition combination with 23...Nxg3!! wins, but requires visualizing a long king hunt mating variation.|
After 23...Nxg3!! 23. hxg3 Qxg3+ 24. Kf1 (24. Kh1? Rxf2 ; 24. Rg2?? Rf1#), Black wins easy enough with 24...Qh4 but could have forced things a bit more with 24...Qh2!

[Position after the possibility 24...Qh2! ]
After 24...Qh2!, White has nothing better than 25. Rxf7 when Black cranks up his mating attack with 25... Qh1+! 26. Kf2 Rxf7+ 27. Ke3 Qh6+ 28. Kd4 Qf6+ 29. Kd5 Qf5+ 30. Kc6 Qd7+ 31. Kd5 c6+ 32. Kd4 Qg4+ 33. Re4 Qg1+ 34. Re3 Rf4#.
If White responds to 24...Qh2! with 25. Ke1 then 25...Rxf2! 26. Rxf2 Qg1+ wins easily.
