The program play a relatively strong game(it can beat me every time).
Compiled with FPK pascal.  Source is included.

The program uses:

negamax w/alpha-beta pruning
killer moves
a bunch of positional terms in the evaluator


There is no opening book for this version.  I am rewriting in C using
bitboards and the free DJGPP compiler.  I already have the GUI finished,
with mouse support.  The new version will use null move,
hash tables, opening book, endgame databases, and will be much better.
