That's really impressive, even considering the fast hardware.  The last
time I tried, I got 289/300 at 1 second/position, 293/300 at 3 seconds,
294/300 at 5 seconds, 295/300 at 10 seconds, and 298/300 at 20 seconds.

The remaining two positions, number 100 and 230, are *never* solved.
I can let my program analyse for hours, but it still doesn't find
the solutions.  In both positions, it thinks it is winning, but
never finds the right moves.

In number 100, Gothmog switches back and forth between Be3 and Kb3, both
with a score around +4.  In number 230, it plays Rh7 with a score around
+3.3.

What tricks do you use which helps you solve WAC100 and/or WAC230?

And, I *REALLY* hope you're *NOT* planning to use that machine at CCT6,
because I'm probably going to be there with my PIV 2.4 GHz, searching
less than 200 kn/s ...   :-)
