This is the original version of the chess game in Squeak. It is smaller and faster than the versions found in Squeak 3.6 or later and also fixes various bugs in the game by reverting all the so-called "cleanups" that were done by people who had no idea what they were doing and what they were breaking (hint: Replacing "foo size = 0" with "foo isEmpty" is NOT a valid transformation unless the receiver is a Collection). This version also includes the castling fixes done by Rick.
