Sep-27-07  bogo78: Quite a few of us were wondering if 16.Bxh7 was necessary or perhaps 16.Bxf6 would do. When i 'solved' the puzzle i overlooked the simple defense to the later alternative. Namely black has ...Nbd5 and the attack will be stopped.
Sep-27-07  MostlyAverageJoe: <TrueBlue> & <marteinn> Your lines depend on black's blunder. After 14. Bxe7, black's best response is 14... c4

Not that it saves the black, but c4 makes it a bit more difficult for white who now has 2 pieces en prise.

  whiteshark: Found that pretty soon. Exchanging+sacrifying ♘♘♗ to weaken black's position to such an extent that ♕+♗# is unavoidable.
Sep-27-07  Crowaholic: <MostlyAverageJoe: or could run 14...Kh8 and lose slowly, being a piece down and subject to a nasty attack after 15.Nxf6 Nxf6 16. Bxf6>

I suppose you mean 15. Nf6, but anyway, 15. Nd6 looks much stronger to me. If Black doesn't exchange Q for N now, then 15. ..Qd7 16. Nxf7+ (16. Qxf7!? Qxe7) Rxf7 17. Qxf7 Qxe7 (17. ..Bb7? 18. Bh6!) 18. Bxe7 Nxe7 19. Qxe7 Bd7 20. Qd6! looks more than just crushing.

  YouRang: Yee haw! Got the whole thing. Not that hard really, all of the moves were hanging there like ripe apples.

It was just a matter of picking them in the right order so that: (1) the moves are forcing and (2) we end up with a badly exposed king under deadly assault. In a position like this, nothing is quite as deadly as a Q+B attack with the bishop at f5 and the queen at h6.

Sep-27-07  Grampmaster: I played 16. Bxf6 instead of Bxh7.

Maybe someone with a search engine can prove that 16. Bxf6 doesn't win for white.

In playing it over in my head that was the line I was calculating.

Sep-27-07  twin phoenix: <venk98> 16. Bxf6? does not work. i had planned on continuing in such a manner also. alas i thought i had found the correct combination but missed entirely that 16. Bxh7+! was necessary.(so no i don't get credit.) if 16. Bxf6,N-g6 followed by 17.Q-h5,N-d5 saves black. we were so close and yet so far away...

  HFlew: Cool, I got the whole line :)

I like it when Bxh7+ works, wish it would in my games!

  YouRang: <Grampmaster: I played 16. Bxf6 instead of Bxh7. >

The purpose of 16. Bxh7+ is (1) to eliminate the last pawn defending the black king, and (2) allow the queen to join the attack with tempo (that is, with check), which deprives black time to defend.

If 16. Bxf6, then 16...Ng6 seems to gum things up for white. White might try 17. Qh5 (threatening Qh6 - Qg7#), but 17...Nd5! kills this threat by threatening to take out the bishop.

Sep-27-07  TrueBlue: MAJ, allow me to disagree. 14 Bxe7 f5
15. Nxf8 and white is ahead with the material. 14 Bxe7 definitely deserves full credit.

  fm avari viraf: White's position looks very dynamic & all set to unleash the forces on the Black's vulnerable Kingdom. Hence, the start of a beautiful combination is 14.Nxe7+! Nxe7 15.Nf6+ gxf6 16.Bxh7+! Kxh7 & is all over for Black.
Sep-27-07  MostlyAverageJoe: <TrueBlue: MAJ, allow me to disagree.> There is no disagreement, really. 14.Bxe7 is quite viable (as mentioned in my second post on the first page of kibitzing). Not as crushing as Nxe7, but clearly winnable.

However, 14. ... Nxe7 is a rather bad response by black, and your line should not rely on it. There are plenty of better choices for black: the f5 you mentioned, and also any of the following seems better (this list may be inaccurate, as it comes from a fairly shallow multi-line analysis by Hiarcs):

14... cxd4
14... c4
14... Bb7
14... f6
14... Bd7
14... h6

Thus, 14.Bxe7 has another disadvantage in that it produces less forcing, more complex situation.

Of course, relying on a blunder by this particular player of the black pieces might be justified, given the forced mate he walked into as soon as he played 14...Nxe7 in the game :-)

  patzer2: For today's puzzle solution, Edward Lasker exploits Black's weakened castled position with the forcing 14. Nxe7+!!, setting up the demolition pseudo-sacrifice 15. Nf6+! with a mating attack.
Sep-27-07  zb2cr: <TrueBlue>,

You must have dropped a move there somewhere--after 14. Bxe7, f5 White can't play 15. Nxf8.

Sep-27-07  pawnofdoom: Amazingly I got this one, but sort of screwed up the line

My thoughts were a long the line of 14. ♘xe7+ ♘xe7 15. ♘f6+ gxf6 16. ♕h5 ♘g6 17. ♗xf6, threatening Qh6 the next move. Does anyone know if that works? My Fritz won't open right now

  playground player: OK, I understand about Ed Lasker. But what about Bill Steinitz? Ron Capablanca? Spud Tarrasch, and all the rest of those lesser-known, not-quite-as-brilliant relatives of famous chess masters?
Sep-27-07  Crowaholic: <playground player>: This site features games of a Tigran V. Petrosian (the most famous one by far), a Tigran L. Petrosian and a Tigran A. Petrosian. :-)
Sep-27-07  TheaN: 3/4

I've failed, on day four. What a shame. I was looking at 13.Qh5 but I guess f5 locks it all up. Damn. Not that I mind too much, as I have a busy weekend coming up. I'll retire 'til Monday XD.

Sep-27-07  willyfly: Material is equal and it's still early in the game. White's c6♘ is en prise.

Candidates
a-14 ♗xe7
b-14 ♘xe7+
c-14 ♘d6
d-14 ♘f6+

due to my being in time trouble I'm only going to post the line I think is best - here tis'

14 ♘xe7+ ♘xe7 15 ♘f6+ gxf6 16 ♗xf6

now to look
-----
if my math is correct that's a triple sac - very very nice

Jan-12-09  WhiteRook48: if it weren't for that e8-Queen and f8-Rook blocking White up...
Oct-03-09  WhiteRook48: 16 Bxh7+ self block
Aug-21-10  sevenseaman: Its a kind of a juggernaut that sucks Black up.

  MissScarlett: According to Helms in <The Brooklyn Daily Eagle>, Black resigned after 15.Nf6+. The occasion was the annual intercity match between the Manhattan and Franklin chess clubs.
