Artic Knight
Nxg7 wins for white in the following line:
1. Nxg7 Kxg7
2. Bf6+ Kg8
3. Qf3 then Qg3+ wins for white.
But what if Black plays 1. ... Bxc4 instead? I don't see a clear win for white ... e.g.,
1. Nxg7 Bxc4
2. Qg4 f5!
and black may take the knight with Qxg7.
So White should maybe play 2. Qh5 instead of Qg4. I'm not clear on how the game should continue at this point. I think 2. ... f5 is still playable for black as he must protect the f6 square.
'Just found the winning line for white ...
1. Nxg7 Bxc4
2. Bf6! Bxe2
3. Nf5+ Kg8
4. Nh6++
So black must counter with 2. ... Be7 to stop the discover check. Not sure how the game should continue from here ...
Nice analysis, kibitzer. Your last line is in fact how the game actually proceeded. You can find all the gory details here.
Famous Stein Portisch game, many who have seen it will recall Nxg7
