Home * Engines * Chesley

an open source chess engine by Matt Gingell under the GNU Public License, written in C++ and supporting both Windows and POSIX. Chesley is compatible with the Chess Engine Communication Protocol. It takes its name from Chesley B. “Sully” Sullenberger, the pilot who successfully landed a airplane on the Hudson river around the time Matt was getting started [1]. Chessley is a bitboard program, and applies rotated bitboards not using the outer square optimization for a fourfold table reduction [2]. Matt made experiments with the Score data type in Chesley, and replaced 32-bit integer by Float, taking the same space [3].
