Chess Tiger,
a chess engine by Christophe Théron. Chess Tiger and the version dubbed Gambit Tiger [1] competed the WMCCC 1997, WCCC 1999, WMCCC 2000 (3rd place) and the WMCCC 2001, won three times the French Computer Chess Championship, three times the French Programmers Tournament, two times the Spanish Computer Chess Championships, three times the Dutch Open Computer Chess Championship, and the BELCT 2001. As once mentioned by Christophe, Chess Tiger uses a resource friendly 16x16 Board Vector Attack approach [2].

Chess Tiger is suited to run on various platforms, an UCI compatible PC version is available from Lokasoft [3] , and Chess Tiger 15 from ChessBase [4] . Recent versions focus on PDAs, Tablet computers, and Smartphones, such as the free Palm version [5] , and the releases for Apple's iPhone, iPod touch, and iPad, all running under Apples iOS Mobile operating system [6], also incorporated in Apple's Chess Pro - with coach [7].

The only tiger playing chess in the world! This program, developed under the Caribbean sun, is a blitz specialist. Recently it has greatly been improved and rewritten for 32 bits processors, bringing its level close to the best "state of the art" PC computer chess.


Chess Tiger used to be a very good tactical program, but has been improved to include more positional knowledge and is now a more balanced chess player. Chess Tiger is still developed under the sun, in Guadeloupe (French West Indies).
