|Jan-20-12|| ||Memethecat: <gofer> I had to google anastasia,s mate, I know the position but its nice to put a name to a face. Someone on this site used the analogy of pieces casting shadows, this position puts me in mind of that, as does Carlsons exceptional final move when he beat Aronian earlier this week.|
|Jan-20-12|| ||Patriot: Black threatens mate in one. White has a rook for two pawns.|
34.Re8+ looks like the only try.
A) 34...Kh7 35.Qd3+ and 36.Qxc2
B) 34...Bf8 35.Rxf8+ Kxf8 (else it is similar to A) 36.Nf5+ Kg8 37.Nxh6+ followed by 38.Ng4 looks pretty good (covering h2/f2)
The tricky part of this seems to be where to move the knight for a good discovered check. I also looked at 36.Nxf7+ but 36...Kg7! leaves white without a decent check.
Oh! The direct 37.Qf8+! is the killer I missed! Too bad because I've seen this tactic before. And besides...it's a check, which I'm supposed to be looking at first!
|Jan-20-12|| ||Patriot: It looks like I missed quite a bit in this problem. 38.Ng4 is deadly for white since 38...Qe4+ forces mate. And as <morfishine> points out, 35...Kg7 36.Rxf7+ wins the queen for an easy win.|
|Jan-20-12|| ||WiseWizard: <morfishine> On your first diagram you wrote 40...Qe4 saves black, but white has the deflection 41. Rf6+ getting a won Q v R ending or mate after 41...Ke5 42. Qd6#. Thats the line I went for, missing the simple 37. Qf8+ funnily enough I was telling myself look for the most forcing move at every turn.|
|Jan-20-12|| ||Penguincw: Hehe. Close enough!|
|Jan-20-12|| ||Phony Benoni: <LoveThatJoker> This procedure was given in the Kibitzer's Café some years ago:|
chessgames.com: Maybe this isn't what you have in mind, but let me say this: anybody who wants to suggest a "tactical exercise of the day" position is free to email firstname.lastname@example.org. It's hard work finding combinations suitable for the homepage.
We need to know the game NUMBER (the number that appears in the URL) and the move number of the solution. If it's Black to move, add 0.5 to the move count. Keep in mind, this is the number of the solution move. The diagram itself will always be displayed right before that move was played.
For example, today's puzzle is "1007697,40" which means that the key move is White's 40th move in game #1007697. One where Black has to move would be something like "1227772,25.5" You don't need to tell us the solution, or which side wins, or if it's a drawing puzzle. We can figure all that out by the game number.
OK, now let me tell you some ground-rules for homepage puzzles:
(a) The side with the winning combination must not be obviously winning the position. (If White is already up a whole rook, we don't care how brilliantly he finished the game.)
(b) There should not be good alternate solutions.
(c) The winning move must have been actually played in the real game. (Otherwise people won't see the answer.)
(d) It must not be a super-famous game. We're not going to take the Evergreen Game or the Game of the Century and expect people to see what Anderssen or Fischer saw.
(e) Extremely complicated combinations that have many subvariations are to be avoided--however, we use them occasionally, especially when analysis exists to confirm the soundness of the combination.>
I asked last year, and this is still in force though obviously the criteria have changed a bit. For instance, back in 2003 puzzles were not arranged in the now traditional order of difficulty.
|Jan-20-12|| ||CHESSTTCAMPS: Black is down a rook for two pawns, but threatens mate. There is no viable passive defense available to protect h2, so white must seek a knockout punch of his own. There's only one forcing sequence available and it works:|
34.Re8+ Bf8 (Kh7 35.Qd3+ followed by Qxc2 wins) 35.Rxf8+ Kxf8 (Kg7/h7 36.Rxf7+ wins) 36.Nf5+ Kg8 (Qb4 / Rc5 37.Rd8#; Ke8 37.Qe7#)
Here I stumbled briefly, examining 37.Re8+ and 37.Nxh6 before I remembered the Anastasia's mate that was available against the defenses in the last parenthesized note.
37.Qf8+! and black gets to choose the finish:
A) 37... Resigns
B) 37... Kh7 38.Qg7#
C) 37... Kxf8 38.Rd8#.
Euwe was generally sporting, so I'll go with C.
Look for challenging weekend puzzles after a light Thursday/Friday.
|Jan-20-12|| ||Nemesistic: I spent 15 mins looking,and i was on the right lines,i just didn't see the Queen sac a coming..|
|Jan-20-12|| ||LoveThatJoker: <Phony Benoni> Thanks for the thorough reply, man! That's how CG likes it, eh? Cool. |
I just might take some initiative and review my older posts via my CG profile and e-mail them the puzzles that I've already suggested in the comments field.
I sincerely appreciate you taking the time to inform me on this.
|Jan-20-12|| ||SpoiltVictorianChild: Got it really quickly, actually...|
|Jan-20-12|| ||Rosbach: King dragged back to f8 by the Queen and mate. 34.Re8+ Bf8 35.Rxf8+ Kxf8 36.Nf5+ Kg8 37.Qf8+ Kxf8. 38.Rd8#|
|Jan-20-12|| ||FSR: I've seen this combination in Foldeak's book on the Chess Olympiads, making it easy for me. 34.Re8+ Bf8 (34...Kh7 35.Qd3+ and mate next). 35.Rxf8+! Kxf8 (35...Kg7 36.Ne8+; 35...Kh7 36.Qd3+ Kg7 37.Nf5+! ) 36.Nf5+ Kg8 (36...Ke8 37.Qe7#; 36...Qb4 37.Rd8#; 36...Rc5 37.Rd8#) 37.Qf8+! Kxf8 (37...Kh7 38.Qg7#) 38.Rd8#|

|Jan-20-12|| ||kevin86: In desperation,white starts checking and it leads to mate.|
Black can only survive,at the loss of a rook.
|Jan-20-12|| ||Once: I think some of CG's ground rules have slipped a little over the years. It's not unknown to have multiple good solutions. We had one of those just the other day.|
And CG will sometimes give us positions where the best move isn't the one that was played - for instance when the player missed the best continuation.
So I think that (b) and (c) from the list that <phony> quotes are "usually" rather than "always".
Perhaps it would be a good time for CG.com to update this and put it in their FAQ?
|Jan-20-12|| ||JG27Pyth: Felt good when I finally saw the Queen sac to put the ribbon and the bow on the finish. Lovely combination -- new to me but it seems like it ought to be a classic.|
|Jan-20-12|| ||Phony Benoni: <FSR> Interesting that this game would appear in Foldeak's book on the Olympiads, since it wasn't played in one. It's certainly beenpublished enough other places, though. My introduction was Coles' <Epic Battles of the Chessboard>.|
|Jan-20-12|| ||FSR: <Phony Benoni> D'oh! You're right, I saw it someplace before, but not there.|
|Jan-20-12|| ||doubledrooks: I went with 34. Re8+ Bf8 35. Rxf8+ Kxf8 36. Nf5+ Kg8 37. Qf8+ Kxf8 38. Rd8#|
|Jan-20-12|| ||poachedeggs: It is not "difficult" because continued check is the only option...
Then it boils down to seeing that a Q+ on 38 is the only viable move rather than a R+ on 38...|
The only other thought is where the N needed to go on 36...but the discovered + to f5 seems natural & looks very dangerous...and eliminating the flight square g7...so that probably lit the light bulb of the Q sac.
|Jan-20-12|| ||zakkzheng: I was really amazed when
I saw the move Qf8+,I am prety sure I saw this example before,oh pooy me.
|Jan-20-12|| ||sfm: Ah, this one, always loved it. What fireworks!|
|Jan-20-12|| ||sfm: If Euwe played 31.Nxd6!! but didn't consider what follows, until 33.-,Qf4, he is one sloppy fellow. Then on the other hand, if he saw all the way through to 37.Qf8+, he is one amazing genius. I believe in the latter.|
|Jan-20-12|| ||Once: Ah, um, Euwe was playing black. He lost. So I ... er ... guess he didn't see all the way through to 37. Qf8|
|Jan-20-12|| ||The Rocket: got it! very nice! but not difficult level to me|
