Originally posted by paulbuchmanfromficsThat's a good point; I have personally never been victimized by that, but that's because as you said the pawn on e6 stopped and Bf5 ideas.
You left out one key ingredient.
Black must have his queen's bishop locked in (by e6).
Long ago, I learned the hard way that Bxh7+ Kxh7, Ng5+ Kg8, Qh5 can be refuted by Bf5 (if it is available) !!!
The queen's bishop must not be able to defend the h7 square from queen invasion.
That is all I will say at this time (a very general rule).
(I have two games in progress with the classical bishop sacrifice right now !!!)

It is a Lasker game!
Lasker- Thomas, 1912

And the actual finish was 14.h4+ Kf4 15.g3+ Kf3 16.Be2+ Kg2 17.Rh2+ Kg1 18.Kd2#.
Here's one from January:
16...Kg6 might have held out longer. I spent about thirty minutes with the analysis board working out the variations, which I seem to recall gave me at minimum a one pawn advantage and his king remaining exposed on the center files. When he moved back to the eighth rank after the knight check, it was over.
Game 3759097 The success of the Kings Bishop x h7 sacrifice is as always,knowing when it is correct to do so. Just one rather simple example among many 😉
Not of course a true sacrifice as the bishop remains on board throughout the game,however as the bishop remains trapped to games end it is effectively a 'sacrificed prisoner',playing no further active part in this game. A piece held hostage but also acting as an effective hostage taker.A bishop of a very unbishop like nature!?😲

Well it's not my trick question, it's Edward Winter's - read on.
The game I posted was actually K.S. Kibbey v D.T. Dorman. USA 1942
and the score is correct.
Proof and more about Lasker v Thomas (which is the game you refer to)
is here on Edward Winter's site.

By far the best chess site on the whole net.
I too thought it was Lasker game when I first saw it.
Originally posted by greenpawn34I have seen somewhere (some Internet site) that there are about a dozen different score sheets available of that game, all with different finishes (some finish O-O-O# too) and move orders/moves to get to the position with Qxh7+.

OK, I've written this message and decided to check out Winter's page on it. It was that page indeed 🙂
Originally posted by chesskid001I was the victim of such sacrifice in my last FICS game. It's an embarrassing loss: http://blog.chess.com/diskamyl/weekly-fics-game-analysis-2
I just finished a game Game 6058677 where I had a chance to use the classic Bxh7 sacrifice; from what I've read and from what I've learned through experience, the Bxh7 sacrifice is most likely to work when
A) A Knight can check on g5 and a Queen can get to h5 (these are the usual prerequisites for the sacrifice)
B) A bishop exists on the c1-h6 ...[text shortened]... ot work? Or perhaps any more ideas what makes the sacrifice successful and what makes it fail?

Yes it is. I have that book, and the entire section on the Bxh7 sac makes it worth the read alone.
>Yes, I agree. That chapter on the classic bishop sac is alone worth the price of the book. This is one of my favourite books. I heartily recommend it.
think in your game its sound as the king is very isolated but usually
it doesn't work.
i play this bishop sacrifice all the time and gives a nice attack on the castle :

[Site "www.uchess.com"]
[Date "2009.3.1"]
[Round "?"]
[White "solstice"]
[Black "Black Star"]
[Result "0-1"]
I will show you a game where I thought I had a winning attack but was just 1 tempo short.... The end of the game is bad, I know 🙁
