a bitboard-based, chess programming open source toolkit by Sam Tannous, writteb in Python, which includes a simple chess engine which applies alpha-beta search and iterative deepening, able to communicate with a GUI via the Chess Engine Communication Protocol. The goal of the project is to aid in implementing a Shannon Type B chess programs, where execution speed becomes less important then code clarity and expressive power of the implementation language .
