The French program '''Joker''' was a variation of the [[Écume]] chess engine by [[Marc-François Baudot]] and [[Jean-Christophe Weill]]. The idea behind it was "Entropic extension", if the position was not stable enough, an [[Extensions|extension]] of the search was made (the stability was considered as a function of the last move). The idea came from [[Vincent David|Vincent David's]] Ph.D. thesis <ref>[[Vincent David]] ('''1993'''). ''[http://cat.inist.fr/?aModele=afficheN&cpsidt=161774 Algorithmique parallèle sur les arbres de décision et raisonnement en temps contraint. Etude et application au Minimax]'' = Parallel algorithm for heuristic tree searching and real-time reasoning. Study and application to the Minimax, Ph.D. Thesis, [https://en.wikipedia.org/wiki/%C3%89cole_nationale_sup%C3%A9rieure_de_l%27a%C3%A9ronautique_et_de_l%27espace École nationale supérieure de l'aéronautique et de l'espace], [https://en.wikipedia.org/wiki/Toulouse Toulouse], [https://en.wikipedia.org/wiki/France France]</ref>.
Joker won the [[FCCC 1993|2nd French Computer Chess Championship]]. Écume hold the second place. Joker did show some impressive play, but the idea was abandoned, the search was too slow (Even if it was coded in [[Assembly|assembly language]]).
