Subject: Free Piece/Square Tables

Author: Stuart Cracraft

Date: 16:41:42 09/21/04

Enclosed please find piece/square tables published
by Beal and Smith in "Learning Piece-square Values using
Temporal Differences", published in ICCA v22/no.4 of
December 1999.

The tables are based on mailbox. These have been sized
for a millipawns-based program. I have experimented with
both 1/10th the size and 10x the size of these and neither
of those, nor these, improve my program's result (actually
worsen it), so I'm sending these out if anyone wants a set
to start with or experiment with.

In the actual program, the king's table is averaged in
with a similar table that penalizes the king on the edge
in the endgame. This entry assumes the start of the game.
