Subject: King and pawn ending position for evaluation

[D]3k4/8/1p3K2/8/4P1p1/6P1/7P/8 b - - 0 91
A position from a game (Yace 0.99.56-Crafty 18.12) in a slow P3-550mhz machine
at 75 minutes per side with some 5 men Nalimov TB's.

Crafty could have avoided this position and draws some moves back, but it
follows in this direction. Is this not caused by the evaluate winner() function?
BTW Bob, what are the bases that this function can tell more correctly that one
is winning/losing/drawing in a given position? Will somebody let Crafty analyze
this position in a faster machine?

How your favorite engines react to this? The target is for black to accept that
white is winning (this is perhaps a mate in more than 45 moves) in a reasonable
period of time considering that we are in an ending stage.

Regards,
Dinan
