Home * Engines * Rhetoric



Rhetoric, an UCI compliant chess engine by primary author Alberto Sanjuan supported by chess advisers 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. Rhetoric 1.2, released in February 2014 , was a huge improvement due to the introduction of singular extensions and late move pruning, and further by performing evaluation tuning inspired by the method proposed by Peter Österlund .
