Celes
Celes, (31337)
a chess engine by Johan Hutting, at times supported by Marcel Veldhuizen, written in Delphi compliant to the Chess Engine Communication Protocol [1],
and since version 0.70 the UCI protocol. Celes was initially called 31337, but that's not a valid ICC and/or FICS name, so Celes was used [2].
It applies alpha-beta inside an iterative deepening framework with aspiration windows, further using the killer and null-move heuristic.
Celes utilizes a main transposition table, a separate opening book transposition table, which covers transpositions of opening lines, and caches its evaluation results due to a evaluation hash table and pawn hash table [3].
