Various games implemented 2002-2003 by Derek Nalls and L. Lynn Smith.

Special thanks to Ed van Zon and Jens Markmann along the way.

All of the chess-related games in this collection are played upon boards which, with the pieces for each of the 2 players set to their opening positions, maintain perfect bilateral, geometrical symmetry via vertical and horizontal axes.

I welcome thoughtful, constructive correspondence from anyone.

Please report any errors or inefficiencies observed or discovered thru playing my games or upon examining their programming (*.zrf).
