|Jan-02-06|| ||Whitehat1963: Why does black play 22...Re7? Is this necessary? What happens if 22...Bxd5 instead?|
|Jan-02-06|| ||larsenfan: Whitehat1963: Why does black play 22...Re7
It seems that if 22...Bxd5 23 Kf5 must win
|Jan-02-06|| ||Whitehat1963: Huh? Que? What? Pardon?|
|Jan-02-06|| ||larsenfan: Sorry, my mistake, I mean 23 Nf5 and I do not see how black can defend g7|
|Jun-29-07|| ||whiteshark: Position after 18... f6:

If 19... Bxd5 20. Nxd5 cxd5 21. Qh6 f5 22. Bxf5 gxf5 23. Nxh5 Re7 24. Qg5+ Kf7 25. Qxf5+ Kg8 26. Qg5+ Kf7 27. Qxd5+
But maybe there are some better defence moves....
|Sep-24-11|| ||dzechiel: White to move (20?). Material even. "Very Difficult."|
Well, my gut says that the key is...
so I'm going to start looking at it. Black kinda has to take the bishop, the only other viable option is to move the rook, lose the h-pawn and go down two pawns with a lousy position.
20...Nxg6 21 Qh6
With the obvious threat of 22 Qxg6+.
Defending the knight with the king doesn't work, ie: 21...Kf7 22 Qh7+ followed by 23 Qxg6. And defending the knight with the bishop looks even worse: 21...Bf7 22 Nxh5 and there's no good way for black to stop 23 Qg7#.
White threatens 23 Qg7#. How does black defend? He has to moves:
22...Qe7 23 Nxd5
looks pretty strong. The queen cannot defend herself and g7 (for instance 23...Qf7 24 Ndxf6+ forces black to give up her majesty).
Hmm..., I'm not sure what to do about this. I think I must have wandered astray.
Time for me to check and see how this game played out.
|Sep-24-11|| ||scholes: What if 24 .. Qh7|
|Sep-24-11|| ||scholes: After 24 .. Qh7 white liquidates into a won ending. But is not it better to play 23 .. d5 winning the pinned bishop|
|Sep-24-11|| ||mario1031: Instead of 21...Ngf8 could 21...Nh4 have defended? with the idea of 22...Nf5 if no other forced move was req'd?|
|Sep-24-11|| ||DarthStapler: I at least considered the first two moves|
|Sep-24-11|| ||sevenseaman: Today a strange kind of mood enveloped me. No sooner had I opened the
<cg> home page, I found I did not want to do the puzzle at all. 5
seconds and I stopped even looking at it. This eerie feeling has never
ever come over me before today. I wanted to just shut it out or quickly see the solution and be done with it.|
Normally I am always agog, looking forward keenly to the daily POTD.
Now I wont say I am superstitious but I almost always obey my instincts.
I am very <wary, chary and scary> of the blue mood. Seeing the solution
would equate with throwing a 'work of art into the gutter', converting
24 hours of a possible pleasure into 24 hours of inane, drab and a
distracting wait. Who knows what comes up on Sunday.
Finally I shut off the computer in order to be able to delve into my
odd reaction to a very desirable and keenly looked forward to daily
I am at a loss and feel rather empty to disappoint you by saying
that I could not unravel the 'mystery of the mood'. (I am sharing all
this personal detail because I am hopeful of getting some wise counsel
from someone among us who understands psychology and human nature better).
I reopened after an elapse of more than 2 hours, after finishing my day's
chores. I wanted it badly enough now, without knowing why.
The first move that hit me was to sac my LSB, and went on from there;
<20. Bxg6 Nxg6 21. Qh6 Ngf8>
Now the decision to go Nxh5 (for Qg7+) or Nxd5 to nullify the e8 R in case Black answers Bxd5. Since Black is sure to use the R or the Q to defend; I chose the latter.
<22. Nxd5 Re7>
Black will perhaps refuse the N, and I have,
<23. Nxe7+ Qxe7>
Now this is a dilemma; Nf5 or Nxh5?. Both look good and both will be
answered by Qf7. Because of my need to push the 'f' P I am loathe to
block its possible access to f5. So now I choose to go;
<24. Nxh5 Qf7 25. f4 ~ 26. Re3> 1-0
Its as good a time for Black to surrender as he is ever going to get.
My consolidated line;
<20. Bxg6 Nxg6 21. Qh6 Ngf8 22. Nxd5 Re7 23. Nxe7+ Qxe7 24. Nxh5 Qf7
25. f4 ~ 26. Re3> 1-0
|Sep-24-11|| ||SimonWebbsTiger: @<sevenseaman>
there are times I am not in the mood to work on any chess. It happens at times when I feel "chessed out", i.e. I have been playing and looking at so much chess, I actually fancy putting the 64 squares aside and watch a favourite TV series as well. Chucky is probably "chessed out" right now after a hard month in Russia and isn't really looking forward to the Masters; he appeared to be a bit tired of chess after his win v. Ponomariov.
|Sep-24-11|| ||Robespierre: Wow, no chance whatsoever to come within a light-year of the answer. My first 4 guesses at the initial move were all wrong.|
|Sep-24-11|| ||scormus: Material equal but W has a a lead in development and B has disorganised pieces with a horribly compromised K position. There must be something.|
In the "spirit of the puzzle" I'll go for the B-sac 20 Bxg6 and I suppose B has no realistic option other than ... Nxb6. Then 21 Qh6 Ndf8 22 Nh5 threatening # on g7 and B has 4 possible moves to defend
22 ... Qd7 23 Nxf6+ 1-0
22 ... Qe7 23 Nxd5 Bxd5 (anything else then 24 Ndxf6+ 1-0 ) 24 Rxe7 Rxe7 25 Nxf6+ 1-0
22 ... Qc7 23 Nxf6+ Kf7 and 24 Nxe8 Rxe8 25 Qh5 is the best I can find W keeps the initiative and R+3p vs. N+B, should be enough
22 ... Re7 23 Nxf6+ Kf7 24 Rxe6 Nxe6 25 Qxg6+ Rg7 26 Nxf6+ Kf8 27 Qf5 and W will win the d5 pawn so will have N+4p vs. R again with initative
I feel I missed something better but I now check
|Sep-24-11|| ||scormus: Yeah, I thought Nxd5 should come in somewhere but I didnt see the neat R-lift continuation. Of course B cannot capture 22 ... Bxd5 23 Nf5 1-0.|
At least I got "the Dzechiel norm" so I shouldnt be too upset.
Yesterday and today have been a lot of work so I might take tomorrow off.
<sevenseaman> Nice work!
|Sep-24-11|| ||sevenseaman: <Scormus> To show how Black cannot afford to take the N on d5; <22 ... Bxd5 23 Nf5 1-0.> Thats a killer <upper cut>! What more did you want?|
|Sep-24-11|| ||abuzic: I like the line posted by both <scromus> and <dzechiel> but with some deviation: |
20.Bxg6 Nxg6 21.Qh6 Ndf8 22.Nxh5 Re7 23.Nxf6+ Kf7 white has 24.Nh5 Ke8 25.f4 <(or maybe 25.Nxg7+) Rh7 26.Rxe6+ Kf7 27.Rxg6! Rxh6 28.Rxh6.
Now black has no sound continuation even after white has no Q. I think white wins here.
Another black defence is:
20.Bxg6 Nxg6 21.Qh6 Nh4, white may continue 22.Nxh5 Nf5 23.Qg6+ Kh8 24.Rxe6 Rxe6 25.Qxf5 and the d5 pawn will fall.
If black defends with 21...Ngf8 then 22.Nxd5! (as posted by <sevenseaman>) Re7 23.Nxe7 Qxe7 24.Nxh5 and if black responds with 24...Qh7 25.Nxf6+ Nxf6 26.Qxf6
|Sep-24-11|| ||abuzic: whiteshark: Position after 18... f6:......
But maybe there are some better defence moves....>
After <18.e4> black could defend with 18...h4! 19.Nf5 Bxf5 (the bishop will be taken anyway after 19...gxf5) 20.exf5 Qf6;
or 18...h4! 19.Nge2 h3 20.Nf4 hxg2 21.Kxg2; black has nothing to fear in both variations.
|Sep-24-11|| ||stacase: 20 Bxg6 is obvious the rest requires some thinking.|
|Sep-24-11|| ||scormus: <sevenseaman> Thanks, but but for the 2nd weekend in a row I missed the killer R-lift. A points win is not the same as a TKO.
Hang on, I've just see <abuzic> post, 21 .. Nh4 is interesting, and I never considered it. But your line looks good for W anway.|
<SWT> Yes, I can imagine how Chuky feels. A couple of tough puzzles is enough to sort me out
|Sep-24-11|| ||eaglewing: <sevenseaman: Consolidated line
24. Nxh5 Qf7 25. f4 ~ 26. Re3>
Re3 not for ~!
25. f4 Bg4 seems to need Ng3 probably followed by f5 and the bishop (and game) is soon to be lost.
|Sep-24-11|| ||KingV93: Well, my chess brain is on a roll as I guessed this one correctly today. Two in a row! I figured the g3 had to get into the action and the would come to h6, but how to open the gate? xg6!|
|Sep-24-11|| ||sevenseaman: You are right <eaglewing>. <25...Bg3> throws a spanner in the works.
I never considered this move. Later going to the game score everything
seemed to be hunky dory as Black had played the unimaginative and harmless<25. Bxa2>|
Your line is much sharper and poses a problem. Let us see what can be done about it.
<25. d5 Bxd5 26. Re3 Be6 27. f4 Bg4 28. Rg3 > (If 28...f5 29. h3 will keep the pressure on)
Kindly check and let me know if it comes through.
A tough game, when we have all the analysis!
|Sep-24-11|| ||Old Wolf: This was an interesting exercise, I actually spent an hour analysing (without moving the pieces) with a friend and we came up with all the correct analysis including 25. f4?!|
Black missed 25..Bg4! which ends White's attack, although the computer still reckons white has a won ending after exchanges.
White should have played 25.Re3! when there is no answer to the threat of 26.f4
Other black defences after 20.Bxe6 all lose horribly
|Sep-24-11|| ||Old Wolf: edit: in fact 25. f4 Bg4 can be met by Ng3, threatening f5 which renews the rook lift threat and Black has no defence other than Qh7, allowing Nxf6 with favourable piece play for White.|
