[D] 3b1rk1/r3q1np/p2pPppB/2p1p3/Q1P1P1P1/P4RNP/5P2/1R4K1 w - - 0 0

1.Nf5! gxf5 2.gxf5 Qe8 3.Qxe8! Rxe8 4.Rg3 Ba5 5.Kg2! Kh8?
6.Bxg7+ Rxg7 7.Rxg7 Kxg7 8.Rb7+ Kh6 9.Ra7 Bd8 10.Rxa6 Be7
11.Ra7 Kg7 12.a4 Kf8 13.a5 Rc8 14.a6 Rc6 15.Ra8+ Kg7
16.Re8 Rc7 17.Rb8 (1-0), Bleiman-Vainger, 1984.

(If  5...Rea8 6.Kf3 Kh8 7.Bxg7+ Rxg7 8.Rxg7 Kxg7 9.Rb7+ Kg8
10.Rd7  is painful, Gelfer)

This didn't look right, so I gave the position to Fritz 5 and
it continues 10...Bc3 11.Rxd6 a5 12.a4 Bd4 13.Rd7 h5 14.Rf7
Rb8 15.Rxf6 -0.72 for Black.  Is this winning for White?

Is this another example of a neat positional sacrifice looking
suspect by a good chess program? Or is Bleiman right?
The tactical accuracy leads to a defensive toughness that seems to
leave a lot of our old literature flawed.
