It plays legal chess (with high confidence). Castling, en passant, promotion, check detection, stalemate, and the 50-move rule are implemented and validated with a 23-case test suite (though not all rules have exhaustive coverage). Threefold repetition and insufficient-material draws are not yet implemented. Beyond unit tests, the engine completed hundreds of tournament games against Stockfish; in rare occasions, an illegal move or protocol error occurred, though it is unclear whether these stem from the TeX engine logic or from the UCI wrapper. This gives reasonable confidence that the core move generation and rule handling are robust, if not formally verified.
