Francesca M.A.D v0.15 released

Actually, I'm probably wrong and bitboards were invented back then.. maybe way earlier.

(But it was still fun to try to build a program back then, when no other source code was readily available. It was a couple of years after I had a working program that I first saw any other chess program source code.. an early version of GNU if I remember).

With an array representation of any kind, I would not expect any speedup going to 64 bits.

The only real advantage of such a compile is to allow for very large hash tables.

ok, thanks. Are there certain data types I should look to consolidate toward?

A switch to bitboard would be pretty major surgery.
For bitboards, the fundamental underlying type is unsigned long long.
