[D]8/1R3pk1/6p1/1P5p/7P/4K1P1/1r3P2/8 w - - 0 1

Does your fav program play this position in the same way as Mr Spasski did?
(Spasski-Antoshin, Sochi 1965) What does Shredder recommend?

The goal is to understand that rook activity is worth more than the f pawn.
The game went on:

1.Kd4! Rxf2 2.Re7! Rb2 3.Kc4 Kf6 4.Re3 Kf5 5.Rb3
I think most proggies have also probs to understand early enough that the
pawn ending after Rxb3 is lost.

[D]8/5p2/6p1/1P3k1p/2K4P/1R4P1/1r6/8 b - - 0 5
5...Rc2+ 6.Kd5 Kg4 7.b6 Rc8 8.b7 Rb8 9.Ke5!
Another point. 'Cos of the horizon effect i.e. Fritz6 misses this move.
To find such prophylactic moves is a too difficult task for the guy.
[9.Kc6? f6 10.Kc7 Rg8 11.b8Q Rxb8 12.Kxb8 g5 13.Kc7 gxh4
14.gxh4 Kxh4=]

9...f5 [9...g5 is not better 10.hxg5 Kxg5 11.Rb4 f5 12.Kd6 f4 13.gxf4+ Kf5
14.Kc7 Rxb7+]
The rest is quite clear.

10.Kf6 f4 11.gxf4 Kxh4 12.Kxg6 Kg4 13.f5 h4 14.f6 h3 15.f7 h2 16.Rb1 Rxb7
17.Rxb7 h1Q 18.Rb4+ Kh3 19.f8Q Qg2+ 20.Kh7 Qc2+ 21.Kh8 Qc3+ 22.Kg8 Qg3+
23.Qg7 1-0.
