|Sep-11-08|| ||Karnatakiaditya: Got it! nice combination!|
|Sep-11-08|| ||chessdude2: 25. N-B6 ch! PxR rips open the g-file with authority, followed by 26. PxP dis ch. Black should defend with K-R1, but the position is hopeless already.|
|Sep-11-08|| ||al wazir: I didn't get this. After 25. Nf6+ gxf6 26. gxf6+ Kh8, I couldn't find a continuation that wins. If 27. Rg7, then 27...Bg6. Now what?|
I spent an equal amount of time on 25. g6 and 25. Nh6+. No joy.
|Sep-11-08|| ||The Bycote: 25.Nf6+ gxf6 26.gxf6+ Kh8 27.Qh6 Rf7 28.Rg5 is the conclusion to chessdude2's suggestion and black is hopeless.|
I think it's a pity black lost this game, I was rooting for him just a few moves before the end. 22...e5! Would have taken advantage of white's artificial position and demonstrated black's strategic superiority.
24...Be8? was the final blunder, a move like Kf7 would not have allowed such a quick finish.
|Sep-11-08|| ||The Bycote: Oops.
25.Nf6+ gxf6 26.gxf6+ Kh8 27.Qh6 Rf7 28.Rg7 is what my line should read in my previous post.
|Sep-11-08|| ||lost in space: 25. Nf6 is the shot!
25. Nf6 gxf6
or 25... Rxf6 26. gxf6 Bf8 27. fxg7 28. Rg5 Qf6 29. Qxh7
or 25... Kf7 26. Nxh7 Ke7 27. g6+ Kd7 28. Rg5!
26. gxf6+ Kh8
or 26...Bg6? 27. Qxh7#
27. Qh6 Rf7
or 27...Ta7 28. Rg7!
28. Rg7! and Black can resign
|Sep-11-08|| ||Dr. J: Black's 26th is a horrible blunder What happens after 26 ... Kh8? White can win the Black Queen by 27 Rg5. But then after 27 ... Qxh3 28 Qxh3 Rxf6, while White has Q for R+B, his Bishop is extremely bad, and Black threatens counterattack by b4. So: (1) Is this best play for both sides? and (2) What is the evaluation of the position reached. Analysis, please? |
Meanwhile, has anyone determined the theme of the week? Remember:

|Sep-11-08|| ||The Bycote: Dr. J: I found a much better continuation for white than 26...Kh8 27.Rg5. |
See my previous posts.
|Sep-11-08|| ||The Bycote: To continue my previous line...
25.Nf6+ gxf6 26.gxf6+ Kh8 27.Qh6 Rf7 28.Rg7 Qxh3 29.Qxh3 Rxg7 30.fxg7+ Kxg7 31.Qxe6 and black loses every one of his center pawns. White wins easily.
|Sep-11-08|| ||Strongest Force: In the old days of the 90's when i use to play blitz against the top online comps, this was the perfect way to play- the perfect anti-comp setup. Therefore, at a glance, i could see the knock-out blow.|
|Sep-11-08|| ||Dr. J: <The Bycote> Very nice. The crucial difference is that in your extended line the e6-pawn is not defended.|
|Sep-11-08|| ||Confuse: al wazir... i find 26. Qh6 to be pretty strong continuation in your line. let me know your thoughts.|
|Sep-11-08|| ||aruntal: Easier than tuesday and yesterday puzzle. Only two forcefull moves Nh6+ and Nf6+.
Lets first look at Nh6+,
1.Nh6+ gxh6 (Night forks queen and king, black has to play gxh6)
and I dont see any winning combination for white from here.
So the solution for the today puzzle must be Nf6+ :)
1.Nf6+ now white can capture the night in two ways...either with rook or pawn.
both moves are bad for black.
|Sep-11-08|| ||Once: We join the game as white's kingside attack is poised to crash through. He has an ugly-as-sin bishop on d2, but apart from that is doing well. A far advanced knight (always good for combinations), queen and two rooks are all pointing at black's king. Yum.|
25. Nh6 gh 26. gh+ Kh8 looks tempting, but then what do we do? The black king looks safely tucked into the corner and we have blunted our h file attack with the white pawn.
25. Nf6 is the "puzzle move" - putting a piece on prise in more than one directon. Now 25. .. gf 26. gf+ Kh8 27. Rg5 or Qh6 look great for white. Ditto 25. ... Rxf6.
But what about 25. ... Kf7? Can black escape the net? Nope 26. Nxh7 threatens both the Rf8 and g6+

Our mating attack has fizzled into swapping a knight for a rook and pawn. Not as glamarous but still ought to get the job done.
I'd still worry about the billy-no-mates on d2, though.
|Sep-11-08|| ||AnotherNN: Saw 25.N-f6+ but couldn't see anything concrete after 25 ...K-f7. However, now I see that 26.Nxh7 wins the rook too (because if it moves, e.g., 26...R-h8 then 27.p-g6+ K-g8 28.Nf6+).|
|Sep-11-08|| ||MostlyAverageJoe: <Once: 25. Nh6 gh 26. gh+ Kh8 looks tempting, but then what do we do?>|
How about 27. Qh6 to keep the vulnerable h7 pawn in place, with the idea of bringing the rook to g7. Looks rather deadly.
MAJ, engine-free today ...
|Sep-11-08|| ||MostlyAverageJoe: OOPS. I see that <The Bycote> already looked at this, and indeed it seems winning for the white.|
|Sep-11-08|| ||wouldpusher: 24. g6!! is much stronger than the text. 24. ... xg6 25. g1 or 24. ... h5 25. g3 or 24. ... h6 25. xh6+! or 24. ... hxg6? 25. h7+ seems to be all winning lines for white.|
|Sep-11-08|| ||stacase: Knight to f6 check opens Black up like a can of sardines.|
|Sep-11-08|| ||johnlspouge: Thursday (Medium): Znosko-Borovsky vs M Lewitt, 1906 (25.?)|
White to play and win.
Material: N for B. The Black Kg8 has 2 legal moves. White has a battery Rh3 and Qh4 attacking Ph7, which is defended by Qf5 and Kg8. The White Ng4 can give check at f6 or h6. The White Bd2 is hopelessly bad, but Rg1 faces Kg8 with Ng4, Pg5, and Pg7 between, suggesting its activation with a clearance sacrifice.
Candidates (25.): Nh6+, Nf6+
Black can accept the sacrifice, feasibly only with 25…gxf6:
(1) 25…gxf6 26.gxf6+
Black cannot feasibly interpose [26…Bg6 27.Qxh7#], so Kg8 has 2 flight squares:
(1.1) 26…Kh8 27.Rg5 (threatening 28.Rxf5 and 28.Qxh7#)
Black cannot meet both threats, so White wins at least Q for R+N, to start.
(1.2) 26…Kf7 26.Rg7#
Black can decline the sacrifice 25.Nf5+ by fleeing:
(2) 25…Kh8 26.Qxh7+ Qxh7 27.Rxh7#
The mate is called Arabian mate.
(3) 25…Kf7 26.Nxh7 (threatening 27.Nxf8)
26…Rh8 27.g6+ Kg8 [Qxg6 28.Rxg6, and if 28…Kxg6 29.Qh5#]
28.Nf6+ (threatening 29.Qxh8#)
29.Kf8 Qxh8+ 30.Ke7 Qxg7+
Black is down a R with nothing to play for.
|Sep-11-08|| ||johnlspouge: In my variation (1.1), as others have pointed out, 27.Qh6 is better. According to Toga 27.Rg5 is sufficient at almost +2 P, however, and the main difference is picking up Ps after Black exchanges Q for R.|
|Sep-11-08|| ||Samagonka: First Thursday puzzle I ever fully fathomed. At least the first three moves. Great feeling.|
|Sep-11-08|| ||Woody Wood Pusher: 25.Nf6+, Kf7 26. Nxh7, Ke7 27.g6+, Kd7 28.Rg5!, Trapping the black queen|
It does seem black's best play is
25...gxf6 26. gxf6, Kh8 27.Qh6, Ra7 28. Rg7,Qxh3 29. Qxh3, Rxg7 30. fxg7+, Kxg7 31. Qxe6 + -
|Sep-11-08|| ||openingspecialist: does black have a hope of drawing this?

|Sep-11-08|| ||Woody Wood Pusher: yes that looks completely drawn, why?|
