Sjeng can prefer a different move for reasons as simple as a differently
sized hashtable, or even a different compiler. Sometimes the phase of
the moon even seems to matter ;)

The learning files should be no problem; Sjeng stores how deep in
the search it got, and uses them accordingly.

I've briefly analyzed the game and the loss looks fair and square
to me. If you feed the critical position to my program, you'll see
it doesn't understand it. Many other amateurs seem to have problems
with it, so it's a nice testposition.
