IntelliChess,
an experimental Chess Engine Communication Protocol compliant open source chess engine by Sari Linder [1],
written in C#, released under the Apache License, Version 2.0.
The program relies on bitboards, and uses magic bitboards to determine sliding piece attacks [2], magics borrowed from Rival [3].
IntelliChess applies a fixed depth negamax alpha-beta search with transposition table without any selectivity and quiescence search [4].
It uses Bayesian networks for evaluation and tuning its weights.
All scores and bounds within evaluation and search are double floats.
