On the Spacial Limits of Tri-D Chess

On the Spacial Limits of Tri-D Chess is a textbook publication about three-dimensional chess authored by Hathoz.

History
Hathoz wrote the book prior to 2274, before he found chess unchallenging and thought himself unbeatable.

In February 2274, Spock dined with Hathoz and other senior officers aboard the USS Venture (Constitution class). While eating plomeek soup, Spock mentioned that he owned a book-tape copy of On the Spacial Limits of Tri-D Chess and invited Hathoz to play a game. Eventually Hathoz agreed, and it ended in a stalemate.
