Subject: Lucky bug

My program was down a couple of pawns against Crafty in an opposite bishop
ending with rooks on the board, when suddenly it traded off a couple of pawns,
traded off the rooks, ran with its king into a corner, and declared the position
equal:

[D]8/8/3b4/8/7k/6pp/8/5B1K w - - 0 1

I couldn't figure out why it was smart enough to have a draw score for this
position, then it occurred to me that Crafty has B + wrong RP :-)

I'd been rearranging some data structures and introduced a bug.  Fortunately,
the bug caused the program to play the ending perfectly.
