Rhetoric,
an UCI compliant chess engine by primary author Alberto Sanjuan supported by chess advisers Jose Antonio Morillas and Juan José Corbalán 1, 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 2, and therefor promises an interesting playing style. Rhetoric 1.2, released in February 2014 3, 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 4 5.
