Ok... I ran it and what it sees is that the bishop is lost, but it gets another
piece back, so it is fairly even (Crafty isn't happy with black here until
depth=14, as it seems black is walking into an attack while trying to save the
bishop. At depth=16 it becomes much less happy. I get this:

I didn't get another move at depth=16 as I started with a 10 minute time limit
and it ran out.
