As I mentioned in another post, crafty has a "hole" here.  IE if you move
the black king one square from where it is, and put a white pawn on that
square, the static eval says "white wins" because of the distant passer.
But the instant the distant passer evaporates, the term goes away.  In
normal positions, this doesn't hurt a lot as by the time it has to give
up the passer it can see that it wins pawns on the other side.  But here
it isn't so easy as black has a few horizon moves to throw in at key times.

I almost have this fixed, finally, which will likely let it find a5 almost
instantly since king moves lose and the axb5 evaporates the queenside with
white's king too close to stop on the kingside.
