Celes, (31337)
a chess engine by Johan Hutting and at times by Marcel Veldhuizen, written in Delphi and supporting the Chess Engine Communication Protocol [1], and since version 0.70 the UCI protocol [2]. Celes was initially called 31337, but that's not a valid ICC and/or FICS name, so Celes was used [3]. It applies alpha-beta inside an iterative deepening framework with aspiration windows, further using the killer and null-move heuristic. 31337/Celes played three CSVN tournaments over the board, the ICT 2001, DOCCC 2002 and the ICT 2003, as well as four CCT Tournaments, CCT3, CCT4, CCT5 and CCT6.
