No-one seems to have picked up on my comment that Steve shouldn't
abandon the position as a draw because Fritz actually has a winning
position. So here's the winning plan (based on analysis by Fischer).

The current position is:

[D]8/2k5/1p4R1/1K6/P2b4/8/8/8 w - -

Stage 1: White plays his king to a6 and rook to b5, producing a
position similar to the following:

[D]8/2k5/Kp6/1R6/P2b4/8/8/8 w - -

Stage 2: With his rook on b5 preventing b5+, he plays his king to a8.
Black must keep his king on c7/c8 to prevent the White king penetrating
to b8, c8 and (eventually) b7.

[D]K7/2k5/1p6/1R6/P2b4/8/8/8 w - -

Stage 3: White brings his rook to the c-file.

[D]K1k5/8/1p6/8/P2b4/8/8/2R5 b - -

Stage 4: Black must still keep his king on c7/c8. This allows White
to take advantage of the pin on the bishop to push his pawn to a7.

[D]K7/P1k5/1p6/2b5/8/8/8/2R5 w - -

Stage 5: Losing a move with the rook if necessary, White reaches
the following position:

[D]K7/P1k5/1p4R1/8/3b4/8/8/8 w - - bm Rc6;

Stage 6: White sacrifices his rook at c6 to free his king and promote his pawn.

I doubt whether Fritz will find Fischer's winning idea, but it
deserves the chance!
