What a great problem!
Not only is the setup interesting, but there are so many interesting
alternatives.

The best thing about watching the computer pound on this position is the
manic-depressive evals.  Happy-Sad, Happy-Sad, Happy-Sad, Happy-Sad...
Like watching a bouncing ball.  I did not solve it yet.  I might give it a big
pound tonight.
