Jokarian chess
From Memory Alpha, the free Star Trek reference
Jokarian chess is a variant of the Earth game of chess.
In 2369, Jadzia Dax visited Benjamin Sisko's quarters to see if he wanted to join her in a game of Jokarian chess. (DS9: "The Nagus")
It was never revealed if this was an alien chess-like game by a "Jokarian" species or from "Jokar", or rather a Human variant on Earth chess. However currently no chess variant seems to exist with this name.
