Will,
You said in jest that "perhaps no *amature* program can see the draw".
I wonder how long it takes Amature to see it. You never posted any
output.
As a teaser, let me post this -- the lastest Screamer try.
It dropped c8=Q at 11 seconds, but didn't see Nc6+ until ply 15 at 1:26.
It saw the draw at 3:57, score = +0.00.
