  patzer2: For today's puzzle solution, 21. Nxe6! temporarily sacrifices the Knight, in a demolition combination via double attack, for two pawns guarding the King. After 23. Qxe6, Black is helpless against the dual threats of 24. Rxd7 or 24. Nf6 Bc5+!.

If 22...Kd8, then 23. Qxg7 Re8 24. Bb6! (as noted by <CG>) uses the pin to decoy the Queen and force mate after 24...Qxb6 25. Qxd7#.

Jun-01-06  Fezzik: For me, this was so much easier than Monday's puzzle. I'm still frustrated that I missed that one!
Jun-01-06  aginis: i gotta say i'm pretty disappointed in black his appoint moved the same knight on moves 3-7 that goes against all openning theory i was taught.
Jun-01-06  prinsallan: Saw th Knight sac instantly and checked it for about a minute to see if the continuation was solid.
Jun-01-06  aginis: I'd like to add that 18...Bb8 has to be the worst move of the game. black can't decide is he attacking or defending. judging by such an early c5 prior to castling black is attacking. Bb8 just removes not one but two pieces from the game.after 18...Bf6 19.Nxa7 Qe4 or 19...Qa4 20.a3 RxN 21.BxR QxB 22.Qd3 O-O?! 23.QxN Qb6! 24.b3 (b4 Qd3+ Rd2 Qxa3+ Kd1 Qa1+ ) 23...Qc5!24.Qxb7 Qd3 should at least hold a draw for black.
Jun-01-06  General Patzer: I am getting good at this I guess... I got the continuation in aboot three seconds! :)
Jun-01-06  EmperorAtahualpa: I saw the text moves, but I did not see the variation with Bb6! That's beautiful!

(actually I did look at Bb6, but not in this exact variation)

Jun-01-06  Halldor: Fine puzzle, I got it rather fast but it took a while to calculate the variations.

<I was referring to the variation where Black chooses 22...Kd8. Then comes 23.Qxg7 Re8 24.Bb6!!> I think I saw it because first I examined 22...Kf8 and there I had seen 24.Bc5+ if the knight moves (23...Nf6/b6) with mate. - Black's position is badly developed, and the queen can't take the bishop.

  patzer2: <aginis: I'd like to add that 18...Bb8 has to be the worst move of the game...18...Bf6 19.Nxa7 Qe4...should at least hold a draw for black.> Not exactly! Black's 18...Bb8 was better than 18...Bf6??, which loses quickly to a neat Deflection and Knight Fork tactic.

After 18... Bf6?? 19. Rd6! Qc8 20. Rhd1 a6 (20... Nb6 21. Rxb6; 20... Nb8 21. Rxe6+ ) 21. Rxe6+! Kf8 (21...Kd8 22. Bd6+ ) 22. Nd6 Qc6 23. Bd4 White wins easily.

Black's decisive mistake was 20...Qc7? allowing the winning demolition tactic in the game. Instead, she might have tried 20...Qd5 21.Nxe6 Qxe6 22.Rhe1 Bc7 23.Bd2 Be5 24.Kb1 f6 25.Bc3 0-0-0 (+0.66 @ 14 depth, Fritz 8).

Jun-01-06  RonB52734: <aginis> Regarding white's remarkable steeplechase from moves 3-7, the exact same sequence of moves occurs in an earlier game: Szabo vs P Klings, 1988
Jun-01-06  RonB52734: also notice that black only has one more developed piece than white after move 7, thanks to his own pawnderous opening strategy.

  patzer2: I suspect Black was surprised in the opening by White's rarely played 5. Ng5!? While there's nothing terribly bad about the reply 5...h6, Black has had good success with the developing 5...Bf5 as in Black's wins in Josef Gheng vs J Lechtynsky, 2002 and Szabo vs Schaefer, 1988.

Also, IMHO, worth considering to avoid White's tactics in this game were 8...Nbd7 and 12...0-0.

Although it hasn't been played much and doesn't have a great record at master level, it would appear 5. Ng5!? is at least good for equality and might just catch a strong Caro-Khan player off guard.

Jun-01-06  Rawprawn: Aginis, I think he is a she.
Jun-01-06  zb2cr: Saw that 21. Nxe6 led to an irrestible attack. It's a goodie.
Jun-01-06  dakgootje: found it relatively hard for the day, considering the differant variations. Though of course the first 2 moves werent too hard, so you could have a good indication what the solution would be, after which i think most of us just looked whether the sac was good instead of the best move.
Jun-01-06  Everett: <al wazir: Look, <CG>, I'm a slow typist. If you're going to post the answers I won't bother. >

Curious that you read the postings before solving the puzzle on your own, or at least spending some time with it. Reversing this order may prevent any dissappoint occuring from seeing answers from chessgames or anyone else in the future.

Think al wazir was referring to the answer chessgames.com gave after their questionable first post at this game, instead of the answer to the puzzle

  al wazir: <dakgootje: Curious that you read the postings before solving the puzzle on your own>

I'm afraid no one understood the point of my remark. I worked out my solution (the first message above) *before* <CG> posted it. I checked the moves, corrected my typos, clicked to post it--and only then, to my chagrin, saw that <CG>'s solution was there ahead of it.

  jahhaj: I don't normally say this but I got the answer is 0.5 seconds. I didn't see all the variations, but really, what else are you going to play instead of 21.Nxe6? It's the natural move.

  kevin86: This problem was simple but not easy-lol. It took a little thinking to find the proper combination-but at least the first move was very obvious.
Jun-01-06  YouRang: I could see that 21. Nxe6 fxe6 22. Qg6+ led to a furious attack where White would be able to at least recover the sac'ed piece in addition to picking up some pawns and exposing the Black king.

This, I figured, was "good enough", even though I didn't see any line that forced mate or a huge material gain.

Jun-01-06  dakgootje: <I'm afraid no one understood the point of my remark.> then weve got a winner of most questionable-post of the day!!! congrats! ;-)

  al wazir: <dakgootje>: Questionable? Moi?

I would have deleted my post when I saw I had been scooped--as I have done in the past--but I thought the analysis of my lines B and C justified leaving it up.

As a matter of principle, I feel <CG> shouldn't post solutions until we've all had a crack at the problem.

Jun-02-06  dakgootje: <As a matter of principle, I feel <CG> shouldn't post solutions until we've all had a crack at the problem.> Luckily this was only an incident, so i doubr whether they will do such things more often
