This is not easy for Crafty.  Takes 1:54 to change away from Ng3.  Ng3 fails
low at 18 seconds, depth=11 (quad 700), which means that it would not play this
move in any reasonable time control since once it fails low, it has tha ability
to use a bunch of time to find something better.  at 1:54 Na5 fails high.  I
didn't let it search longer as an ICC game started up and I had to stop the
test...
