As of February 7, 2010, it appears to be one of only two chess engines written in less than 2 kilobytes of C that are able to play full legal chess moves, along with Micro-Max by Dutch physicist H. G. Muller. In 2014 the 1 kilobyte barrier was broken by Super Micro Chess – a derivative of Micro-Max – totaling 760 characters (spaces and newlines included). There is also a smaller version of Toledo's engine, the Toledo Picochess, consisting of 944 non-blank characters.
