A Three-Player Chess Variant by Matt Seabury
About 10 years ago Matt Seabury developed a 3-player version of chess (actually
dreamed the idea). He called it Treyshah. Trey for three and shah for
King (shah being the word where our "check" as in "checkmate" comes from). He ended up
producing and selling about 200 boards. It came in a tournament as well as
a deluxe version. Treyshah was even featured in the "What's New" section in
Here is a scan of the rules booklet for Treyshah that Mr. Seabury was kind enough
to send us. Note that he now has the patent (it is no longer pending), and that
the P.O. Box is no longer valid.
