I posted a simple description in one of the other parts of this thread.  For a
more detailed (i.e. code) description, I posted one here a few months ago and
will try to find it and re-post.  This stuff was all laid out by the Knightcap
people in their several papers.  You can find these papers on the web by
following the links in the computer chess resource center to the Knightcap
program and the "Machine Learning in Games" website.
