Cheese, a Chess Engine Communication Protocol and UCI compliant free chess engine by Patrice Duhamel, written in C. The development started in early 2006, using rotated bitboards and alpha-beta search, improving rapidly, and first released in October 2007 as version 1.0. Since 2012, one can expect yearly updates with steady improvements. Since version 1.8 in March 2016, Cheese is able to play Chess960 (FRC). It is available for all major platforms and operating systems, Windows, Linux, Mac OS and Android [1].
