## BCE - Boo's Chess Engine (aka Bowron - Abernethy Chess Engine)

Once upon a time I wrote a small chess engine in Lisp.  Then I wanted

that engine to go faster, so I rewrote it in C.  Then a while later I

wanted to do a better chess engine, with more features.  I am a big

fan of Lisp so I wrote it in that.  Then, again I wanted it to be

faster so I rewrote it in C.  Then for an AI course project, I added

learning to the C version.  The result has evolved into what you will

find in this archive. It is alternatively known as BACE (Bowron-Abernethy Chess Engine) or BCE (Boo's Chess Engine).  Rob Abernethy and I worked together to add the learning algorithm.

BCE was the basis for [pspChess](https://github.com/cwbowron/pspchess), an open-source chess game for the PlayStation Portable.
