Thanks, Howard! Well the computer was doing almost all of the work. Maybe 4.
..Nc5xd3 is interesting for analysis more than I thought, but I would have to
look further down the line the computer gives too I suspect...

A correction of what I posted, in that last piece of analysis White is still
down 0.56 pawns of course so 4. ..Nxd3 might be an alternative for Black.
Fourteenth ply result was just in. Another possibility is defending the Bishop
and seventh row with 4. ..Rfe8, if on the second move Black places his other
rook on the c-line, 2. ..Ra8-c8 instead of 2. ..Rf8-c8. That is a line Jeremiah
Penery gave, I'm not sure where the original analysis came from, in his post
about the Nolot-positions and DeepThought results too, maybe it is worth a
re-repost:

Weinstein - Elyoseph, Israel 1992
1. Ng5!! hxg5 2. hxg5! Rac8 3. Nf6!! Nb8
3. ...gxf6 4. gxf6 Rfe8 5. Qh5 Rg8 6. Rxc5! Bg6! 7. Qh4 Bxc5
8. Be4 Ne7 9. Kg2 Qd5 10. Bxd5 +-
4. Qh5 Bxf6 5. gxf6 gxf6 6. Rxc5 Rxc5 7. Be4 f5 8. Kg2 Rg8 9. Rh1 Rg7
10. Bh6 Nd7 11. Bxg7+ Kxg7 12. Qxh7+
After 9 minutes, it played 1. Nf6, expecting 1. ...Rfc8 2. Nxh7 Kxh7 3. Ra1.
The score was slightly nagative for white. On longer searches, it went up
to half a pawn and creeping up.
--------------------------------------------------------------------------------
The line with 3. ..gxf6 only ends with +- so it is not an outright win for White
not even in this side-line. But Howard it seems your gut feelings were not so
far off!
Elyoseph by the way I think could be a Fide-master from Israel, Yahoo turned up
this reference in the Fide Elo-list:
2800381 Elyoseph, Harel................. f ISR 2310 0 i
No Mr. Weinstein in the Fide list, maybe it was Kasparov travelling in disguise
under his old name, Harry Weinstein!
