Rhetoric

an UCI compliant chess engine by primary author Alberto Sanjuan supported by chess advisors Jose Antonio Morillas and Juan José Corbalán, first released as free engine in April 2012. Rhetoric is written in C++, and has been trained with Genetic Algorithms to fit grandmaster moves from a collection of games played by [|Anatoly Karpov] versus strong grandmasters, and therefor promises an interesting playing style.
