Home * Engines * Pigeon

an original 64-bit UCI chess engine, written in C++ by Stuart Riffle. Pigeon is open source, released under the MIT license. To allow for SIMD and GPU acceleration, much of the critical code is branch-free. It performs a monochrome move generation approach, color flipping the board after make move [1] .

Pigeon is very much a work in progress, and any feedback is welcome!
