Well, I must admit to being particularly proud of my newest addition,
being able to play chess online against each other. It's not perfect
(can't tell if you are in checkmate, for instance), but it's quite workable, and can handle most o fthe rules of chess (normal movement, en passant, capturing, castling, queening, etc), and it's got lovely and varied capturing messages!

In any case, you can read more about it in HELP CHESS. If you don't know standard chess notation and/or rules, read HELP CHESSRULES. It's fairly long, so be warned.

Penned by my hand on the 12th of Valnuary, in the year 229 AF.
