I've been advocating this for years, but nobody paid much attention. By using
probability theory, an evaluator can make more principled use of the available
information. If you understand the value of a piece of information for
evaluation, and you understand how it relates in probability theory terms to the
rest of your evaluation information, you know exactly what to do with it. In the
long run, it can only help program strength.

That's how the crushingly-strong othello programs work. Chess is more
complicated, but the same principles apply.

It is more work to get started with.
