This sounds really wrong.  IE I can't imagine beating any program with any
program 20-0, unless the loser is really a new program with lots of bugs, a
fairly basic search, and a very rudimentary evaluation.  And even then a
program like that ought to win a game here and there.

20-0 is a huge margin of winning.  I'd check the 'bionic' log file (assuming
they left that in) to see if it is searching some ugly number of nodes per
second (like 100 or something) and if so, then try to find out what is
going on...

I'm not sure the 'winboard interface' you are using is really well-thought-out
yet, and programs can be sensitive to a lot of nonsense like forcing it to read
the entire move list in before each move.  As a program doing a lot of stuff
at the root might be tricked into doing that for every move, and end up
spending its allowed time pre-processing and not searching.

needs examination...
