295/300 on WAC at 5 seconds per position on a 300 MHz machine is not unusual for
the best programs. But the 5 problems above that are missed by crafty at 5
seconds are all solved fairly quickly (17s, 6s, 11s, 9s, 11s):
choose from book moves randomly (using weights.)
choose from 5 best moves.
book learning enabled
result learning enabled
position learning enabled
resign after 5 consecutive moves with score < -9.
