Dec-18-08  peristilo: I agree with Dzechiel: this position is too hard for a thursday puzzle! You have to see lots of moves to find the right way. I got very tired after some tries!
Dec-18-08  yoyosd: I just recently started playing chess, so I'm just trying to learn even the basics. Can someone please explain to me the finish if knight takes Queen after the player resigned? I can't see the end game at all.
Dec-18-08  cyclon: A beautiful combination!
Dec-18-08  The beginner: <yoyosd>

After NxQ, white will follow up with Nf7 checkmate, as the king cant move anywhere. The mate pattern is called smothered mate.

Dec-18-08  The beginner: Also I agre the position was a litle hard for a thursday.

I gues the lesson to be learned here, is always look for the posibility to deliver a smothered mate when you have both knights close to the oponents king in the corner.

Dec-18-08  yoyosd: The beginner: Thanks! I think it's funny someone with a beginner name is helping me out, that makes me pre-beginner. But I do enjoy this site, I'm trying to play as much as possible and even if I don't understand most of these professional games I find them very interesting.

  whiteshark: Been here, seen that.
Dec-18-08  The beginner: <yoyosd>

You are welcome. Regarding my user name, well I gues it is kinda misleading, as I am hardly a beginner anymore. I just got stuck with the name, from when I joined the site.

Also if you really want to improve your chess. you have come to the right place here. There are a lot of very strong players here, that can give advice, and athmosphere is very friendly here.

You could also check out these articles.

And buy software program for example

That will help you improve a lot, to recognize patterns, and tactical oportunities.

Dec-18-08  drnooo: Hey, guys, once you see the knight at H sac everything else is so forced it is an easy puzzle: look at all the checks, totally forcing for one thing: then how all of blacks pieces are blocking everything, absolutely everything they should be protecting. Maybe the second knight sac is a little hard but even that ..excuse the expression.. leaps out at you since the queen check follows on its heels. The rating somewhat hard is fine for Thursday.
Dec-18-08  SamAtoms1980: I saw moves 21-24 of the main variation, would have seen 25-27 if I could imagine that far.

I was worried about 22 Qg4+ Kf8 but after 23 Nd7+ and 24 Qh4+ it seemed like the can of whoop-@%$ was about to get its lid torn off.

Dec-18-08  drnooo: One thing however totally unrelated: whats the story with the Fide chumpionship. Who are the next challengers now that that has changed: thanks in advance for the info.
Dec-18-08  njchess: I got the first three moves easily enough e.g 21. Nh6+ gxh6 22. Qg4+.

22. ... Kf8 23. Nd7+ Ke7 24. Qh4+ f6 25. Nxf6 is winning for White, but Ng7 seemed to save Black's position after 23. Nxf7 Bf8. Then, I realized 24. Nxh6+ Kh8 25. Qxe6 won with a smothered mate by Nf7++. Nice play by White.

The best alternative to Nh6+ is Bxe8, but I saw no clear win for White. His position was already better than Black's and Bxe8 did not appear to improve it in the near future. I also thought this move was inferior because it allowed Black to open up the position.

8. ... c5 can result in an isolated queen pawn for Black, which is one reason why dxc4 followed by b5 is often played.

11. ... a5 while playable is not immediately necessary. Of higher priority is breaking up White's attack with cxd4. After 12. Nxd4 dxc4 13. Bxc4 the position is essentially even. The text move also has the defect of allowing White's light squared bishop a comfortable outpost.

13. ... Rc8 is an alternative to the text move and I think a stronger move. 14. Rfd1 is preferred over e4 (e.g. 14. e4 Nf4 15. Qe3 Ng6).

14. ... Qb8 is forced because Black's queen has nowhere to go when the position opens up since White has not taken on c5 (e.g. dxc5 Bxc5 allows Qe7).

15. Ne5 is fine, so is dxc5. But 15. ... Rc8? is a costly mistake. Better was cxd4 after which White has only a slight advantage.

The rest is all downhill after White's accurate play.

Dec-18-08  Utopian2020: I did not see the smothered mate because I calculated black 22...Kf8. However, Kf8 still leads to mate as black lasts only a little longer.

  Domdaniel: After 21.Nh6+ Kf8 white doesn't have to take on f7. More effective is 22.Nd7+ Ke7 23.Ng8+! Kd8 24.e4 and Black falls apart.

  johnlspouge: Thursday (Medium):

R Buhmann vs B Saeheng, 2008 (21?)

White to play and win.

Material: Even. The Black Kg8 has 2 legal moves, both dark squares on the back rank. White has a local superiority on the Black K-side, with Bb2 and Ng4 attacking dark squares and Ne5 in the area. The White Rc1 and Rd1 are both on open files. The White Bb5 attacks Ne8, which therefore burdens Rc8 and Qa8. The White Qe2 requires activation. The White Kg1 is temporarily secure, although the Black Bc5 and Nd5 attack Pe3, and Black has a battery Qa8 and Bb7 pointing at Pg2.

Candidates (21.): Nh6+, Nf6+, Nxf7, Bxe8

21.Bxe8 Rxe8 [else, drop a N]

22.Nh6+

I decided to capture Ne8 before the Nh6+ sac. Toga declares the variation winning (about +2 P), but not anywhere near as good as the text. I soon got lost in the ensuing complications, which were impressive for a Thursday.

It is not bad. (Toga gives it +2.0 P.) It just is not as good as the game variation.

Dec-18-08  ZUGZWANG67: Did anyone consider 22. Nd7 ?
Dec-18-08  yoyosd: The Beginner: Thanks again! I appreciate the advice. I gathered you were more than just a beginner, but I appreciate the lack of an over bearing tone. I wasn't sure how people on this site were to true beginners, but so far it seems pretty friendly.

Most of us are still learning. If you take that attitude, you will fit right in.

Welcome aboard :)

I considered the idea in some of my variations. Although a mate-in-one threat is often as good as a check, I was disappointed today ;>{ For your suggestion (as in the variations I did not give), Toga II 1.3.1 indicates 22.Nd7 is inferior (humans can improve at the end of the complete computer variation):

[ply 15/53 time 02:05 value +0.37]

22.Ne7 23.Qh5 Bc6 24.Ne5 Nf5 25.Bxc6 Rxc6 26.Nxc6 Qxc6 27.Qg4+ Kf8 28.e4 Nfd6 29.Re1 f6 30.Qxe6 Re7 31.Qd5 Qxd5 32.exd5 Nc7 33.Bxf6 Rxe1+ 34.Rxe1 Nxd5

My chessforum gives detailed instructions on how to download Toga, which is freeware.

Dec-18-08  MostlyAverageJoe: <<MAJ> Does your algorithm rate this position in the "Thursday" difficulty range? >>

Midpoint between Thursday and Friday. Could fit either day.

  patzer2: For the Thursday Dec 18, 2008 puzzle solution, White plays the winning demolition 21. Nh6+!! In the game continuation, it leads to a smothered mate after 26. Qg8+! Nxg8 27. Nf7#.

  whiteshark: In the final position Black's ♕ looks a bit misplaced. By contrast look at White's ♕.
Apr-23-09  WhiteRook48: actually, Black's Queen looks more misplaced than the black a7-rook in the final position

  gawain: I didn't have chance to try this one in December, but found it while looking up Fedorchuk's victim in today's puzzle. Buhmann gets to be the victor this time with a brilliant combination. This was supposed to be "Medium" difficulty???
