I have nothing stunning to report, I'm afraid. On my relatively humble PIII-733,
CM9000 did not announce a mate in over 30 minutes, and I didn't have more CPU
time to devote to the problem. Maybe I'll let it run overnight on Monday (on my
slower PIII-600, unfortunately). There was a VERY long fail high on d6 at depth
14 that took up most of the time.
