|Nov-24-11|| ||cyclemath: <Isolani: Does 36 Nf6+ win much faster? Am I missing something here?>|
Yes, it's mate next move, whatever Black does.
|Nov-24-11|| ||lost in space: ohh, I thought it is Severus Snape|
|Nov-24-11|| ||morfishine: <35.Ng4!> is just too much for Black to handle: Simultaneous threats (36.Re8+ & 36.Nxf6+) cannot be met with one move. |
Happy Turkey Day to those of you who celebrate this Holiday!
|Nov-24-11|| ||CHESSTTCAMPS: White has a knight for a bishop and solid protection of his king position; black has an unprotected e8 because of Bc8. White should exploit this weakness by creating a winning double threat. (Didn't Botvinnik say that all tactics are based on the double attack?)|
A) 35... fxg4 (or Qg5, Qd4, and others) 36.Re8#
B) 35... Rxg4 36.Re8+ Kg7 37.Qh8+ Kf7 38.Rf8+! Ke7 39.Qxf6+ Kd7 40.Rf7+ Ke8 41.Qe7#
B.1) 37... Kg6 38.Rg8+ Bg7 (Kf7 38.Rf8+ transposes back to main line) 39.Qxg7+ Kh5 40.Rh8+ Qh6 41.Rxh6#
B.2) 38... Kg6 39.Rxf6+ Kg5 40.Qh6#
C) 35... Rf7 36.Qg6+ Bg7 (Kf8 37.Nxf6) 37.Nh7+ wins.
If black played on, it was probably in the B line.
Happy Thanksgiving to those who celebrate it!
|Nov-24-11|| ||CHESSTTCAMPS: Missed the game defense :(|
|Nov-24-11|| ||morfishine: <sevenseaman> You commented <...but I do not have the heart to claim any credit> Ahh, now you are being too hard on yourself (which is ironically, something you have accused me of doing in the past).|
IMO, since you identified 35.Ng4 as the killing move, you deserve credit: and not just half-credit, but full credit.
|Nov-24-11|| ||Nemesistic: Id go with 35.Nxf5! If Black re-captures with the LSB,id then play Re8+ forcing Black to take the Rook then White's Queen takes the Black Rook on e8 with a check,then plays Re1..Though im sure there's another way|
|Nov-24-11|| ||Grenache: 35. Ng4 is nice.
But much nicer would have been if White had found 23. Ne5! earlier on -- this is a very strong temporary piece sacrifice that ensures large advantage, if not more.
|Nov-24-11|| ||sevenseaman: Thanks <morfishine>, you are a kind man, a kinder chess player. <35. Ng4> could possibly be treated as good credit but its that 3-move mate that my heart ached for. It went out of my hands even as I pressed the 'Post' button.|
Its like the 'send' button in e-mail. You do not touch it until you are sure of transmitting to the other guy what you have composed. Bad words out of even a good mouth never return. This is in black and white.
|Nov-24-11|| ||morfishine: <sevenseaman> For what its worth, I didn't bother to work out the line(s). I could see that both 35...Be7 & 35...Be5 lost to 36.Nf6+, so I only submitted a partial answer based solely on intuition. Boy, those have back-fired in the past!...but I'm busy today cooking for Thanksgiving |
Justification came when even stubborn Ole 'CRAFTY' could do no better than 35...Qe5. That was sweet. :)
|Nov-24-11|| ||sevenseaman: <Nemesisistic>
<Id go with 35.Nxf5! If Black re-captures with the LSB,id then play Re8+ forcing Black to take the Rook then White's Queen takes the Black Rook on e8 with a check,then plays Re1..>
I had toyed with 35. Nxf5. Its not a good move since the other White R cannot leave base.
After <35. Nxf5 Bxf5 36. Rxe8+ Rxe8 37. Qxe8+ Kh7 38. Re1> Black cuts you off with <38...Be5> The move has considerable tempo on a weak h2.
I tried perpetual but Black can dodge it with a return sac and his position remains more dynamic.
|Nov-24-11|| ||JG27Pyth: Odd for Leroy to find Ng4 in the first place but miss the quick follow up Nf6+ ... I guess I'm the thousandth person to notice that. I had it just like FSR... I thought Ng4 meant Rxg4 and I'd just have to work out the details OTB ;)|
|Nov-24-11|| ||sevenseaman: <morfishine> A happy Turkey Day! When a man cooks its not for nothing; you do make my mouth water. |
(Shouldn't it be called the anti-turkey day?)
|Nov-24-11|| ||Patriot: 35.Ng4 is a logical threat, but unfortunately I did not see it. It's funny that I was trying to find a way to create a double-threat with the knight and open the e-file but for some reason it was not visible to me.|
I decided on 35.Qe8+ Kh7 36.Nxf5. For example, 36...Bxf5 37.Qxb8 Bxh3 38.Be4+ Bf5 (38...Kh6 39.Qh8+ and 40.Qxh3; or 38...Rg6 39.Ra7+ looks very dangerous) 39.Bxf5+ Qxf5 40.Qxd6 looks interesting.
|Nov-24-11|| ||Rosbach: Final moves scenario after Qe7 could be: 41...Kg6 42. Qf6+ Kh5 43. Ne5+ Qxf3 44. Qg6+ Kh4 45.Nxf3#.
But if Black plays: 41...Kg6 42. Qf6+ Kh5 43. Ne5+ Qg4 then it gets more complicated to find the fastest mate...|
|Nov-24-11|| ||LIFE Master AJ: I got the first move ... I worked out many wins, but never finished in the 35...Be7 line.|
|Nov-24-11|| ||YouRang: Luckily, I saw the potential of Re8# right away, so I knew I wanted to move the N. First looked at 35.Nxf5, but then 35...Bxf5 spoils Re8. |
So, I tried 34.Ng4, and found that the double threat of Re8+ and Nxf6+ gave black a hopeless position.
I was surprised to see white miss the quick win after 35...Be7. He played 36.Rxe7?! when 36.Nf6+ is fatal: 36...Bxf6 37.Re8#, or 36...Kf8 37.Qe8#.
|Nov-24-11|| ||chrisowen: Good little inching maneouvre.
Bf6 it stumped in g4 bats up the tail wags on Bd7 wrench a tot see Didier Leroy swinging in knight edges it white huge advantage I need room to free my piece the slide allo elephant e2 to penetrate into e8.
What a breeze in corridor if be7 then nf6 cloaking check hand over entrenched king once more looks like it coming fast. Pawns are not really gauge into it dont you think?
|Nov-24-11|| ||dzechiel: White to move (35?). Material even. "Medium."
White really wants to play Re8#, so it looks like the knight will have to move. Are there any moves that are more forcing than others? Yup, for instance 35 Nxf5 threatens both 36 Nxg7 and 36 Re8#. Unfortunately, both of those threats can be addressed by 35...Bxf5. So are there any other good places for the knight? Yes, white can play
Threatening both 36 Nxf6+ and 36 Re8#. Black has lots of tries here, but none work, eg:
35...Be7 36 Nf6+ Kf8
On 36...Bxf6 37 Re8#.
35...Rxg4 36 Re8+ Kg7 37 Qh8+ Kg6
On 37...Kf7 white winds it up with 38 Rf8+ Ke7 39 Qxf6+ Kd7 40 Qd8#
38 Rg8+ Kf7 39 Rf8+
and we transpose into the line above one move later.
I think this must be it.
|Nov-24-11|| ||Jimfromprovidence: This reminds me of last Friday's puzzle, where the winning move goes right into the teeth of the defense. Today it’s 35 Ng4.

This move not only sets up the more obvious mate threat Re8+, but also the threat Nxf6+, seeing Qe8#.
The game link and puzzle position of last Friday’s POTD is shown below, for those who may have not have seen it

Move 26 for BLACK.
|Nov-24-11|| ||numbersguy70: My worst habit rears its ugly head today. I saw an advantage from Nxf5 and stopped. Must be better at ruling out possibilities for great moves before taking what appear to be good ones. Turns out Nxf5 may not even get more than a draw.|
|Nov-24-11|| ||al wazir: <smith: 35. Ng4 Be5 36. Nf6+ mates on the next move.> Oh, that's a check, isn't it? Too bad. My answer was going to be 36...Qh2#.|
Thanks for the correction.
|Nov-24-11|| ||BOSTER: Black back rank is weak,rook b8 and bishop f6- unprotected.
If you clearly look at black king's position, you would see that inspite of a lot of empty squares king has only one square to go.(f8).|
Move 35.Ng4 not difficult to see, this is <discovered attack>- opening the line for rook e2. Somebody can call this move <desperado>.
Honestly, in books I have never met,that somebody told about the pinning the empty square.
If we regard the term "double attack" in a broader sense,namely not merely as an attack of two pieces, but as a combo of attack and threat, .
Why can't we call the pin-when the piece can't be moved because opponent will get checkmate.
I would call such pin as Boster's pin(kidding).
But if somebody find a refutation, I don't mind.
And now if you understood, that moving the bishop f6 on the "e" file the bishop will be <pinned> you would never play Be5 or Be7.
|Nov-24-11|| ||Penguincw: I was thinking of 35.Qe8. |

|Nov-24-11|| ||sevenseaman: <jimfromprovidence> <goes right into the teeth of the defense>. Thanks for a very apt throwback to I Jones vs J Dueball, 1974. Aah, how quickly even good experiences slip out of one's mind!|
Both are high quality puzzles, well caught by <CG>.
