Folks might be interested in the Common Lisp chess program
"Symbolic" by Steven J. Edwards (of PGN fame). From his ICC
description:
Symbolic is a C++/Lisp chessplaying program written by S. J.
Edwards. Symbolic's C++ source is fully ANSI/POSIX compliant and
portable. Symbolic includes a ChessLisp interpreter for running its
Lisp code. Neither source nor object code is publically available.
One day, all interesting chess programs will be written in Lisp.
Bit twiddling is not a pathway to Artificial Intelligence.
More information on Symbolic can be found in the Computer Chess
Club archives, where Steven made regular progress reports.

His most recent progress reports are on his blog:
http://chessnotation.livejournal.com/
Also, this isn't strictly Common Lisp. He uses his own dialect called
"Chess Lisp", which contains optimized domain primitives such as
bitboard operations.
