Subject: WAC 100, and Crafty

After Bob posted results from Opteron, I decided to do some tests also.
Unmodified Crafty 19.6 compiled with DETECTDRAW on AthlonXP 1600MHz now solves
297/300 in 5 seconds, missing only #s 2, 141, and 230.  #s 2 and 141 are solved
in about 6-7 seconds, and #230 takes less than 10 seconds.

The draw detection helps solve #100 instantly, but when I analyze this a lot I
get some strange results that I'm not sure are accurate.  Obviously, b6 is the
easy winning move, and Be3 should also win.  However, I've done searches
starting with Kb3 which also return winning scores, even as I move several moves
down the line, deep searches still show increasing scores (in the +4 range).

I'd like to know if there is some definitive analysis on this position that
shows that Kb3 (or other moves!) really can't win.  For reference, position is
given below:

[D]8/k1b5/P4p2/1Pp2p1p/K1P2P1P/8/3B4/8 w - -
