RubiChess,
an UCI compliant open source chess engine by Andreas Matthies, written in C++, licensed under the GPL v3.0.
RubiChess started in 2017 as 0x88 engine and soon evolved to a bitboard engine first using rotated bitboards and subsequently magic bitboards (about 24% faster) to determine sliding piece attacks [2]. In September 2020, Andreas Matthies announced RubiChess NNUE [3].
