A. Petrosian - Hazai, 1970 As Dr. Nunn states in his annotations Black's
position is quite bad and he tried Qa7-b6 last move and White couldn't resist
snapping off the queen ... and drawing. The correct scheme is to reject the
"gift" and play Qd2, Kb3, Nc3, Ka4, Na2-c1-b3 and Qxa5 with Black just watching.
I gave this to Crafty 17.13 ...
20 4:33 5.32 1. Nxb6+ cxb6 2. h4 gxh4 3. Qc1 h3
4. gxh3 h4 5. Kb3 Kd7 6. Kc3 Bf2 7.
Kd3 Ke7 8. Qd2 Bg3 9. Qc2 <HT>
Is there a program that "understands" the idea of a blockade, or is this still a
tough area for programmers ... where ply depth doesn't really help but something
in it's evaluation function? From a human standpoint the concept is not that
complex although A. Petrosian stumbled ...
Cheers,
Jim
