Not deep enough yet.

Found a draw. Can't find the win. Other programs seem to do much better with
this one.

Stubbornly sticks to h3. The score was slowly rising, so it might be worth
further investigation

Bruce reported that a deep search gave a score of +1 or so for the key move. I
wonder if this move is not nearly as good.

Crafty just can't get deep enough in one hour on the hardware that I used. But
the alternative move seems to have some promise.

This is the most intersting one to me, from the Crafty output. Look at the
analysis from the run:
