Subject: Brilliant attack by Nezhmetdinov - can a chess program find the moves?

Can your chess program find Black's attacking ideas and correctly evaluate the
positions in this famous game?  Gambit Tiger 2.0 running on my old Celeron
333mhz, at 60 seconds per move, evaluates Black's attack with (??) double
question marks all over the place.  All the Grandmasters who have annotated this
game give Black's moves (!!) double exclamation points.  [ In particular
24....Rxf4!!, and 26....Bg7!!]


IM Nezhmetdinov was one of the most feared and respected tacticians of his day.
World Champion Mikhail Botvinnik said, "Nobody sees combinations like
Nezhmetdinov."  World Champ Mikhail Tal considered Nezhmetdinov a tactical
genius - and Tal lost to him a number of times.

Chess teacher Sunil Weeramantry wrote, "The game Polugayevsky-Nezhmetdinov,
Sochi 1958, certainly ranks among the most brilliant games ever played. It
features an inspired queen sacrifice by Nezhmetdinov. The game is analyzed
in The Modern Chess Sacrifice (McKay, 1978) by GM Shamkovich."

Here's this famous game:

[Event "Sochi 28th RSFSR ch"]
[Site "Sochi 28th RSFSR ch"]
[Date "1958.??.??"]
[Round "?"]
[White "Polugaevsky, L."]
[Black "Nezhmetdinov, R."]
[Result "0-1"]
[ECO "A53"]
[PlyCount "66"]

1. d4 Nf6 2. c4 d6 3. e4 e5 4. Nc3 exd4 5. Qxd4 Nc6 6. Qd2 g6 7. b3 Bg7 8. Bb2
O-O 9. Bd3 Ng4 10. Nge2 Qh4 11. Ng3 Nge5 12. O-O f5 13. f3 Bh6 14. Qd1 f4 15.
Nge2 g5 16. Nd5 g4 17. g3 fxg3 18. hxg3 Qh3 19. f4 Be6 20. Bc2 Rf7 21. Kf2 Qh2+
22. Ke3 Bxd5 23. cxd5 Nb4 24. Rh1 Rxf4 25. Rxh2 Rf3+ 26. Kd4 Bg7 27. a4 c5+ 28.
dxc6 bxc6 29. Bd3 Nexd3+ 30. Kc4 d5+ 31. exd5 cxd5+ 32. Kb5 Rb8+ 33. Ka5 Nc6+
0-1

Here are a few critical positions from the game:

[D]r5k1/ppp2r1p/3p3b/3Pn3/1n2PPp1/1P2K1P1/PBB1N2q/R2Q3R b - - 0 1


[D]r5k1/ppp4p/3p3b/3Pn3/1n1KP1p1/1P3rP1/PBB1N2R/R2Q4 b - - 0 1

Rather than give variations, I'll leave it you and your chess program to analyze
this game.  Good luck to you both!
