To Kamalakanta :
1.Nxg6 fxg6
2.Re7+ Rf7
3.Rxf7+ Kxf7
4.Qxh6 then black has
4....Rg8 and wins.
yet, the line you gave is very close!
Pharaoh
I'm not completely sure about this one but I'm thinking:
1.BxP pxB (1...f6 2.Ng5 is good for white)
2.Nxc6 Rd7
(2...QxN 3.Rd7+ Rf7 4.RxR+ KxR 5.QxR with the threat of 6.Re7+ and winning more material)
3.NxB Bb7 (what else)
(not 3...RxN 4.Qd4+ wins the rook)
4.Re6 Qc5
(4...Qb8 5.Qd4+ Kg8 6.Rxg6+ Kh7 7.Ree6 should win)
5.Qg3 Rf6
6.RxR kxR
7.Qe5+ Kf7
8.Qe6+ Kf8
9.QxR and mate next move.
The beginning moves are correct, i.e. 1.Bxg6 fxg6 2.Re7+ Rf7 but now 3.Rxa7 and white wins due to 3... Rxa7 4.Qd4+. Nice.

oops, on my line disregard 5. Qg3 since black has 5...QxQ lol.
instead, 6.Qg4 should do the trick.
to DV:
but white can't play 2.Re7+ since his knight is on the way! White must play 2.Nxc6 first.
Henryk, I meant of course 1.Nxg6. Sorry, but you could have figured that one for yourself. DV
DV, I've trouble following your lines.
Do you mean to play:
1.Bxg6 PxB
2.Nxg6?
because I don't see what can white play after 2....KxN since white can't play 3.Re7 due to 3....Bxf2+ and winning the queen.
henryk -- He means 1.Nxg6 fxg6 2.Re7+ Rf7 3.Rxa7 Rxa7 4.Qd4+. He's also scornful of your mind-reading ability.
1.Nxg6! fxg6
2.Re7+ Rf7
[2...Kh8 3.Qxh6+ Kg8 4.Qh7#;
2...Kg8 3.Qxh6 (3.Rxa7+-) 3...Bxf2+ 4.Kh1 Rf7 5.Re8+ Rf8 6.R1e7! Qxe7 7.Rxe7 Rf7 8.Qxg6+ Kh8 9.Rxf7 and mate.]
3.Rxa7
[3.Rxf7+ Kxf7 4.Qxh6 Rg8±]
3...Rxa7 4.Qd4+ King moves and Qxa7, winning.
One correction in the line i gave above :
[3.Rxf7+ Kxf7
4.Qxh6 Rg8 NOT ± but black has advantage]
"1.Nxg6! fxg6
2.Re7+ Rf7
[2...Kh8 3.Qxh6+ Kg8 4.Qh7#;
2...Kg8 3.Qxh6 (3.Rxa7+-) 3...Bxf2+ 4.Kh1 Rf7 5.Re8+ Rf8 6.R1e7! Qxe7 7.Rxe7 Rf7 8.Qxg6+ Kh8 9.Rxf7 and mate.]
3.Rxa7
[3.Rxf7+ Kxf7 4.Qxh6 Rg8±]
3...Rxa7 4.Qd4+ King moves and Qxa7, winning."
I guess Black's best defense is 1.Nxg6 fxg6 2.Re7+ Rf7 3.Rxa7 Rdd7!, putting up stiffer resistance...
Kamalakanta
I'm wondering if anyone analyzed this line
1.Bxg6 pxB
2.Nxc6
and if its as good as the
1.Nxg6 PxN
2.Re7+ line.
thanks in advance.
1Nf7 Rxf7
2Re7
1Nf7? Rxf7
2Re7 Bxf2 -+
1.Bxg6 pxB
2.Nxc6 g5 -+
I'm wondering if anyone analyzed this line
1.Bxg6 pxB
2.Nxc6
henryk -- All I can find is 27.Bxg6 fxg6 28.Nxc6 g5 29.Qa4 Bd7 30.Qxa6 which (to my untrained eye, anyway) doesn't look all that wonderful for White. Is there something better? For whatever it's worth, I do find the line 27.Nxg6 fxg6 28.Re7+ Rf7 29.Rxa7 Rxa7 30.Qd4+ pretty convincing.
thanks anon 6:50; I completely overlooked g5.
small details like that is what I overlook most of times.
1Nf7? Rxf7
2Re7 Bxf2
3Qxf2 Rxe7
4Rf1
1Nf7? Rxf7
2Re7 Bxf2
3Qxf2 Rxe7
4Rf1 Bf5
5Bxf5 Rf7 0-1
Following Pharaoh's clue, I just improved on Kamalakanta's solution.
Confession: I searched chessgames database for the game. Here is the link: http://www.chessgames.com/perl/chessgame?gid=1443784
Apparently in the game Black resigned after 1. Nxg6.
Looking harder at the position I suddenly saw this simple tactic:
1...fxg6
2. Re7+ Rf7
3. Rxa7! RxR
4. Qd4+ winning only a pawn. I assess the position as advantageous to White. For example the game may continue as follows:
4.. Kg8
5. QxR Rd7
6. Qd4 Re7
7. RxR QxR
8. Bxg6 Qe1+
9. Kh2 Bd7
10. Qf6 White is clearly ahead.
Or 6..Kh7
7. Re8 winning easily
