Nov-05-06  Nostrils: <Al Wazir>

After 22 ... Qxc6
23 Bh6+ Kh8
24 Qxe5
black has 24...Bh3
then 25 Ne4+ f6
white is winning but the immediate 23 Qxe5 is better.

  mig55: After 30 .../ Qc7 it is not so easy for white
Nov-05-06  ahmadov: Guys, was it easy for everyone to see White's moves 21 and 22?
Nov-05-06  percyblakeney: Too complicated for me, in a real game I would probably have played something like 21. Bh6+ Kh8 22. Nd5 Bxd5 23. Bxd5 Bxb2 24. Rc2.
Nov-05-06  Gowe: <ahmadov: Guys, was it easy for everyone to see White's moves 21 and 22?> I don't know for everyone, but i think a lot of us saw those moves.

But I smell that you didn't see it. I'll tell you something, to see this move you has to understand, to know the double check threat with the knight and the queen (i mean, if Qxc6). And the only way to know those checks, those classical moves, is playing over and over, and playing this kind of positions over and over, and then, your mind will see this kind of moves easily. That's the way a good player makes himself a good player: Playing (and studying of course). The good players known the positions, because, in someway, they had already played those positions. That's the way to know this kind of paths.

Nov-05-06  Nostrils: <Ahmadov: Guys, was it easy for everyone to see White's moves 21 and 22?> I thought so. With the Q on e5 the threat of moving the knight with double check is overwhelming so it's logical to try to displace the black Q. Though I had to check that black couldn't spoil it with 21 ... Bxf6.

Looking at it afterwards fritz prefers almost anything to 21 .. bxc6. It's the third move 23 Rxe6 that is the real killer. I admit I just saw the first two moves and thought that was pretty much it. To really get this I think you had to see black's defence 22 .. Qb8 and 23 Rxe6.

Nov-05-06  percyblakeney: After 21. Bxc6 Bd4 22. Qd2 bxc6 23. Qxb4 Bxf6 white will "only" be up an exchange but it is still winning.
Nov-05-06  Tariqov: Ah, i didn't get it. Couldn't get anything for White and gave up.

So the real hard part is finding Rxe6!,Nd7!, Qxe6! this is more like a positional sac because material are roughly equal but Black has a bad King position. I think most people saw Rxc6,etc probably because they wanted that bishop on e5 dead,etc.

Nov-05-06  percyblakeney: A funny drawing line (even if winning is better...): <21. Nh5+ gxh5 22. Bh6+ Kh8 23. Bxc6 bxc6 24. Rxc6 Qb8 25. Rc8+ Bxc8 26. Bg7+ Kxg7> and black is up a rook and two bishops but can't stop the perpetual:

Nov-05-06  Rubenus: I saw it! I saw the first two moves! A Sunday puzzle!
Nov-05-06  dakgootje: Tried making 21. Bh6 Kh8 22. Bf8 work. It actually did work in most of them variations but for the 22. ...Bxf6 one. Couldnt find anything else. Saw the potential of the a1-h8 diagonal aswel as the option of Bxc6, but didnt dounf the ideas forcing enough
Nov-05-06  RandomVisitor: After Bxc6:

24-ply -1.90 Be5d4 Qe3d2 b7xc6 Qd2xb4 Bd4xf6 Bg5xf6+ Kg7xf6 Rc1c5 Kf6g7 Qb4c3+ Kg7g8 Rc5xc6 Qc7d8 b2b3

Nov-05-06  Fisheremon: <RandomVisitor: After Bxc6:
24-ply -1.90 Be5d4 Qe3d2 b7xc6 Qd2xb4 Bd4xf6 Bg5xf6+ Kg7xf6 Rc1c5 Kf6g7 Qb4c3+ Kg7g8 Rc5xc6 Qc7d8 b2b3>

I was looking at stronger move for Black 20...Rad8 (instead of Rb4), but strikingly it seemed helpless in saving Black from the same motive of combo.

Nov-05-06  Fisheremon: <chessmoron: I got 23. Rxe6! fxe6 24. Rd1>

Certainly Rook sac on move 23 was a right decision leading to the win. In addition if 30...Bc5 (instead of Qc6) 31. Qe6 Rc2 32. Qe5 Qe7 33. Qa1 Bxa3 34. Nd5+ Bb2 35. Nxe7 Bxa1 36. Rxa1 a5, the situation becomes complicated for White.

  playground player: Got the first several moves, including the rook sac. But these are really two puzzles in one: unless Black's moves are forced (and they seldom are), we have to find the right moves for both sides. I just can't think six moves ahead for two third parties. Hard enough doing that in a live game. And I don't know about just feeding the thing into a computer to see what the machine says...
Nov-05-06  independentthinker: Guys,

So after the first white move sacrificing the rook, what happens if black just recaptures with his black pawn?????

Nov-05-06  who: After 22...Qxc6 white would play 23.Qxe5 threatening 24.Ne8+ Kf8 25.Qh8# or 24...Kg8 25.Qg7#
Nov-06-06  ahmadov: <Gowe><But I smell that you didn't see it> LOL. Actually, I saw them. I just asked to see if I was unique ;))

  kevin86: Sundays,for me is not to solve,but to sit back and wonder.

A fine finish,white of course,mates after 33... ♔h5 by 34 ♕h4#

Oct-01-10  sevenseaman: Moshe Czerniak is quite a fox. Till about the 30th move he looked really thwarted. Then he sacrificed a piece I was thinking he would. The tide turned.
Feb-03-12  number 23 NBer: And to think, Czerniak would have been 70-71 when this game was played. And they say calculating abilities diminish in old age!
Apr-20-17  Ibisha Biscotto: "take this piece, perhaps?"
"no thanks." - bolth queens, a few times
