White to move. How should white proceed?
Source: ChessToday.net
1. Bxh7+, Kxh7
(1. – , Kh8 2. Bxg7+, Kxg7 3. Qg4+, Kh8 4. Qh5, Kg7 5. Qg5+, Kh8 6. Qh6 etc.)
2. Qh5+, Kg8
3. Bxg7, Kxg7 (to prevent 3. Qh8#)
4. Qg4+, Kh6 (4. – , Kf6 5. Qg5#)
5. Rf3 and checkmate is not far away.
Bh7 Qh5 Bg7 Qg4 Re3
1. B:h7+ K:h7
2. Qh5+ Kg8
3. Re3
and I don’t see a defense for Black, e.g.
3 … Nf6
4. B:f6 B:f6 (4 … e5; 5 B:g7 K:g7; 6 Rg3+ Kf6; 7 Qg5#)
5. Rh3 and mates next
If Black declines the sacrifice with
1 … Kh8 then 2. Qh5 anyway works fine.
1. Qh5 and white has a strong attack.
bishop takes h7 check followed by Q h5??
1. Bxh7+
1. … Kh8
2. Qh5, threatening
3. Bg6+ Kg8
4. Qh7#
2. … Nf6
3. Bxf6, renewing the threat.
1. … Kxh7
2. Qh5+ Kg8
3. Bxg7, threatening
4. Qh8#
3. … Kxg7
4. Qg4+
4. … Kf6
5. Qg5#
4. … Kh8 or Kh7 or Kh6
5. Re3, threatening
6. Rh3+
5. … Qd8 to delay the mate.
6. Rh3+ Bh4
7. Rxh4 Qxh4
8. Qxh4+ Kg8 or Kg7 or Kg6
9. Qg4+ Kh8 or Kh7 or Kh6
10. Rf3 Nf6
11. Rh3+ Nh5
12. Rxh5#
I like 1. f5 blowing the center open for my heavy pieces. No variations, just general principles.
Lasker sacrifice
Kind of Bxh7
Qh5+
Bxg7
Check with queen and do proper rook shifts
Nice tactic that computers hardly find but a trained tactician guess in seconds
I think Judit did it to Karpov in a blitz game
Paes de Almeida
Im too lazy to calculate, but a double bishop sacrifice starting with bxh7 should win.
If
1. Bxh7+ Kxh7
2. Qh5+ Kg8
3. Bxg7 f5
then
4. Qg6, threatening
5. Bf6#
4. … Rd8
5. Bh6+ Kh8
6. Qg7#
1. Bxh7+ Kxh7
2. Qh5+ Kg8
3. Bxg7 Kxg7 (else Qh8# next move)
4. Qg4+ Kh8
5. Rf3 Nf6
6. Rh3+ Nh7
7. Qh5 and Qxh7# next.
greets, jan
Double bishop sacrifice.
White can clear the h- and g-files and mate with rook and queen:
1. Bh7+ Kxh7
1. … Kh8 Qh5 and out.
2. Qh5+ Kg8
3. Bxg7! Kxg7
3. … f5 4.Qg6
4. Qg4+ Kh6/h7/h8
4. … Kf6 Qg5#
5. Rf3 and nothing can be done against Rh3+
A bishop sack seems unsufficient here, but what about two bishop sacks?
1. Bxh7 Kxh7 (1. … Kh8 2. Qh5 Nf6 3. Bxf6 Bxf6 4. Bg6+ Kg8/Kg7 5. Qh7#)
2. Bxg7
I’m not sure about this, but my guess is that black king becomes too naked here, when white gets his queen and 2 rooks into play.

fajac:
If 1. B:h7+ K:h7
2. Qh5+ Kg8
3. B:g7 K:g7
4. Kg4+ Kh8
5. Rf3
Then:
5 … Nf6
6 Rh3+ Nh7
7 b:c5 Q:c5+
or
7 Kh1 f5
Anonymous (jan):
1. Bxh7+ Kxh7
2. Qh5+ Kg8
3. Bxg7 Kxg7 (else Qh8# next move)
4. Qg4+ Kh8
5. Rf3 Nf6
6. Rh3+ Nh7
7. Qh5
then the same trick as above: 7 … Bc5+
I’ll stick with my solution of yesterday, until somebody convinces me it’s wrong! I think white needs to retain the dark-B to cover f6 and the g1-c5 diagonal, e.g.:
1. B:h7+ K:h7
2. Qh5+ Kg8
3. Re3
and I don’t see a defense for Black, e.g.
3 … Nf6
4. B:f6 B:f6 (4 … e5; 5 B:g7 K:g7; 6 Rg3+ Kf6; 7 Qg5#)
5. Rh3 and mates next
Sorry, I made a rather crucial transcription error when transcribing my analysis of a few minutes ago. The correction is bolded:

2. Qh5+ Kg8
3. B:g7 K:g7
4. Kg4+ Kh8
5. Rf3
Then:
5 … Nf6
6 Rh3+ Nh7
7 Qh5 B:c5+
8 b:c5 Q:c5+
or
8 Kh1 f5

Other attempts to defend against
1. Bxh7+ Kxh7
2. Qh5+ Kg8
3. Bxg7 f5
4. Qg6
are
4. … Rf7
5. Bf6+ Kf8
6. Qh8#
4. … Rf6
5. Bxf6+ Kf8
6. Qg7+ Ke8
7. Qxe7#
How can I make so many transcription errors in one post? In my first line above (response to fajac) white’s fourth move is 4. Qg4+
Anyway, in Ein Steppenwolf’s line:
1. B:h7+ K:h7
2. Qh5+ Kg8
3. B:g7 K:g7
4. Qg4+ Kh8
5. Re3
I suggest that instead of 5 .. Qd8?? black should play
5 … Nf6
6 Rh3 Nh7
7 Qh5 Bc5+
if 8 bc Q:c5
if 8 Kh1 f6
Naturally, I continue to favour
1. B:h7+ K:h7
2. Qh5+ Kg8
3. Re3
and I don’t see a defense for Black, e.g.
3 … Nf6
4. B:f6 B:f6 (4 … e5; 5 B:g7 K:g7; 6 Rg3+ Kf6; 7 Qg5#)
5. Rh3 and mates next
4. … Rf7
5. Bf6+ Kf8
6. Qh8#
Wrong. Queens do not ride in chess.
4. … Rf7
5. Bh6+ Kh8
6. Qxf7 Bf6
and White is better.
@James I. Hymas:
Indeed, 5. … Nf6 escaped my attention.
To my chagrin, I have also found a defence to my line that at least prevents the quick ‘n’ easy mates:
1.Bxh7+ Kxh7
2.Qh5+ Kg8
3.Re3 e5!
e.g.
4.Rh3 f6
5.fxe5 Nxe5
6.Nxe5 Bxh3
7.Qxh3 fxe5
8.Qe6+ Kh8
9.Bxe5 Rxf1+
10.Kxf1 Rf8+
11.Kg1 Qd8
-/+
So, as far as I can see, White has to set aside threats on the h file and try something else, e.g.:
4.Bxe5 Nxe5
5.Nxe5 f6
6.Ng6 Re8
7.Rfe1
I’m a little dubious about the move 5 … f6 in this line, but White has the threat of f4-f5-f6, which looks scary.
