Although the code described on this page will still work as described, it
has been made obsolete by recent developments in GAME Code. Although this
page does describe code very similar to what is still used in many
presets, it no longer describes the code used for the Chess presets, which
has been completely revamped from the ground up. To see the current state
of the Chess preset, go here:

/play/pbm/play.php?game=Chess&settings=Abstract&submit=Edit

and here:

/play/pbm/includes/chess.txt

You will find the code in the include file well-documented by comments.

Comments stored as Markdown will be converted to HTML by Parsedown before displaying them. This follows the Github Flavored Markdown Spec with support for Markdown Extra.
