{Black checkmated} 1-0

The critical move may be black's 56th:

[D]2r5/2Pk2p1/3p4/3PpN2/p3P3/2R3Pp/4bK1P/8 b - -

The move 56. ...g6 is completely losing.  The line goes 57. Nxd6 Rxc7 {Kxd6 58.
Kxe2 Rxc7 59. Rxc7 Kxc7} 58. Rxc7+ Kxc7 59. Kxe2 Kxd6 (all pretty forced), and
white wins the pawn ending.

Even in this position, in an example line, Crafty's static evaluation is very
negative (good for black), but white is completely winning:

[D]8/8/3k4/4p1p1/K3P1P1/7p/7P/8 w - -
