|Nov-27-08|| ||realbrob: Wasn't this too difficult for a Thursday?
Anyway, I got some ideas which had to do with the real solution, but weren't the solution.
My first idea was to start an attack against the White king. BUT 13..Bxh3 14.gxh3 Qxh3 15.Nh2 is a suicide. So my next thought was to remove that annoying white N on f3.
The best way I found was to play 13..Nd4. White can't ignore the threat because his queen is trapped, so has to take the knight. Now after 14.Nxd4 Bxh3 15.gxh3 Qxh3 Black's attack looks more promising.
Then I saw some more confused things, e.g. if White plays 16.Nxf6 gxf6 then Black has the g file open for his rook. I soon realised though that White can also play 16.f3 which probably wins and, what's more, even after 16.Nxf6 gxf6 Black can't really move the king because of Bxf7.
Maybe I made everything too complicated today ;)
|Nov-27-08|| ||Stok: I' d play 13...Ng4|
|Nov-27-08|| ||chrisowen: Looks like a feast of pieces on the table so black is grateful for white's oversight. 13..Bxd5 exd5 Nd4, white recaptures otherwise the queen is dropped and white is down a piece. 13.Nd5 throws it all away.|
|Nov-27-08|| ||DarthStapler: GOt it|
|Nov-27-08|| ||peristilo: I got the basic ideas, but couldnt find the moves! The white queen is traped and there must be a way to exploit that. But its hard to see how. Anyway this puzzle is very instructive! Ill keep this position in my mind.|
|Nov-27-08|| ||karnak64: Oh ... it was BLACK to move ... never mind.|
|Nov-27-08|| ||johnlspouge: Thursday (Medium):
Kmoch vs Samisch, 1928 (13…?)
Black to play and win.
Material: Even. The White Kg1 has 2 legal moves. Black has a battery Qd7 and Be6 attacking Ph3. The Black Re8 faces Qe2, obscured by the Black Be6 and Pe5, and the White Pe4 and Be3, suggesting a clearance combination. All pieces are on the board but otherwise, the position is unremarkable.
Candidates (13…): Nd4, Nxd5, Bxd5, Bxh6
13…Bxd5 14.exd5 [or Bxd5 Nxd5 15.exd5, to the same effect] [else, drop a piece]
14…Nd4 (threatening 14…Nxe2+)
15.Bxd4 [Nxd4 exd4 pins and wins Be3]
15…exd4 16.Ne5 [else, Re8 captures Qe2, which has no flight square]
White has dropped Nf3 to give Qe2 a flight square at f3.
My preliminary analysis should have noted that Qe2 has no flight squares.
|Nov-27-08|| ||withingrace: ya i kind of assumed it was white to move... o well|
|Nov-27-08|| ||agb2002: Black can try to exploit the weakness at h3 with 13... Bxh3. However, after 14.gxh3 Qxh3 15.Nh2, threatening Qg4 and Kh1-Rg1-Rg3 White seems to be winning.|
The black DSB and the rook on e8 converge against the white queen, whose lack of mobility is evident. Therefore, 13... Bxd5:
A) 14.exd5 Nd4
A.1) 15.Nxd4 exd4 and the DSB is pinned.
A.2) 15.Bxd4 exd4 and white will lose his knight to let the queen escape.
B) 14.Bxd5 Nxd5 15.exd5 Nd4 with the same result as A).
Time to post and check.
|Nov-27-08|| ||ceebo: And to finish the game beyond any doubt black plays 23... Rxd4! with the killing Ne4+ in mind.|
|Nov-27-08|| ||whiteshark: There are 2♙+2♗ between ♕e2 and ♖e8
and it took only three moves to remove these obstacles in the way.

|Nov-27-08|| ||amateur1971: Excelent combination, hard to find out here gain of a minor.Comparitively difficult as a thursday puzzle.|
|Nov-27-08|| ||Domdaniel: Pretty. And it shows that Samisch - best known for losing the 'Immortal Zugzwang Game' to Nimzowitsch - could also produce magic in closed positions.|
|Nov-27-08|| ||Check It Out: 13...Bxh6 14.Nxf6+ gxf6 15.gxh6 Qxh6 16.Nh2 Kh8 17.Qg4 Rg8 is the line I came up with, but it just seems wrong.|
I looked at taking the knight on d5 but not far enough. Didn't see the real combo at all.
Happy Thanksgiving CG and all kibitzers!
|Nov-27-08|| ||playground player: "Medium?" Did somebody say "medium?"|
|Nov-27-08|| ||JG27Pyth: Kudos to all who saw the constricted Queen and the latent threat from the rook along the file... I missed it completely... I spent my time looking at the fruitless Bxh3 sac... at least I was able to determine the sac was unsound.|
|Nov-27-08|| ||mkrk17: Took me some 3 minutes to realize that the queen is trapped if N can come to d4. Also, yu notice that Re8 is attacking the Qe2. After that, its all a piece of cake and Bxd5 is the natural choice. |
These are the kind of positions that occur in our everyday blitz games, i hope i get to use this trick sometime soon.
|Nov-27-08|| ||SufferingBruin: <JG27Pyth> Ditto.|
|Nov-27-08|| ||sfm: Surprising that Black suddenly wins in this almost symmetrical position.
And for once the most obvious aggressive move (Bxh3) was not the right one. LOL.|
|Nov-28-08|| ||Once: <JG27Pyth & SufferingBruin> There is something a theme going on this week around restricted mobility/ trapping queens. That gives a big clue for what to look for, but of course is not the sort of hint that you would get OTB.|
|Nov-28-08|| ||kevin86: Black pries open the e-file and wins a piece. Nice!|
|Nov-28-08|| ||njchess: I managed to get this one after concluding that the bishop sacrifice lacked merit for Black. Nh7 is a pretty finesse, though after Re4, it isn't too difficult to see. Anyway, I hope it didn't take too long for Samisch to find the solution, for his opponents sake (he had a reputation of taking forever to move in the pre-clock era).|
|Dec-04-08|| ||patzer2: For the Thursday, Nov 27, 2008 puzzle solution, Black combines the trapped piece and pinning tactics to win a piece after 13...Bxd5! .|
|Dec-04-08|| ||patzer2: The final move 23...Rxd4! clears the way for a decisive Knight Fork threat.|
|Dec-22-08|| ||zdigyigy: Pretty rare to see a master miss a shot like this...Mrs Kmoch probably had dinner waiting for him at home and he wanted to get the game over with....;-)|
