I could not answer that, since I have no idea what they are.

It has an alpha-beta cutoff and the search looks pretty garden-variety to me.
What it allows you to do is switch things on and off (e.g. run with
transposition table and without transposition table. Run with refutation table
and without refutation table).

It is nice code and easy to understand.  I think it would be a good thing for
beginners to play around with.

I know you are working on a chess idea testbed.  How is that effort coming
along?
