Patriot, a WinBoard and UCI compliant chess engine by Vladimir Yelin, and successor of his earlier attempt Kaissa2, a namesake of Kaissa, the first World Computer Chess Champion [1]. Patriot 1.x became commercial in early 2004, bundled with Arena distributed by the Gladiator-Shop headed by Frank Quisinsky [2] [3]. According to the distributor's site, Patriot was improved considerably from March to May 2004 due to better quiescence search, evaluation using mobility tables and implementation of the transposition table [4]. In May 2005, after clone suspicions that the new Patriot 2.0 was based on Fruit [5] became substantial [6] [7], the commercial endeavor ended [8]. Later investigations revealed the previously assumed innocent [9] Patriot 1 and late Kaissas were based on Crafty with many changes [10]
