 * Home * Engines * Kaissa (BY)**

a WinBoard compliant chess engine by Vladimir Yelin, namesake of the first World Computer Chess Champion, the famous Kaissa, and at times Crafty clone. Sergei S. Markoff mentioned Vladimir Yelin also using ideas by Mikhail Botvinnik to determine objects for attack end defence. In 2004, Kaissa2 evolved to Patriot to become a commercial Arena engine. In May 2005, the new Patriot 2.0 turned out to be a Fruit clone , when later investigations revealed the previously assumed innocent Patriot 1 aka later Kaissa versions were based on Crafty with many changes. Investigator Alexander Schmidt stated that later versions of Kaissa released after the Patriot disaster still have Crafty traces inside.
