Play Circular Chess Online with Game Courier

Here is the new preset for Circular Chess. It enforces the rules, and it renders the board as a JPG image at 70% reduction in size.

Note to Developers: Rule enforcement is made possible by some additions to the GAME Code language for using logical directions, similar to how directions are defined in Zillions-of-Games. Study this preset and its include file for details. Read the Developer's Guide for details on the new functions used for logical directions.
