A UCI chess engine written in Rust.
Emerald has support for basic UCI commands, however the implementation is not complete and the engine does not support every command. Emerald also has a few non-UCI commands:
perftsuite: Runs the perft suite ethereal.perft <depth>: Runs a perft test to the specified depth.splitperft <depth>: Runs a perft where each move is also printed with amount of nodes after playing the move.
Emerald uses 8 bitboards into to represent all of the pieces, 2 for each colour, and 6 for each type of piece.
Emerald also uses magic bitboards in order to generate piece moves for sliding pieces (rook, bishop and queen) and lookup tables for the other pieces.
Emerald also generates pseudolegal moves and uses copymake moves.
