Hedgehog, a small and simple UCI compliant chess engine by Eugene Kotlov released in February 2018 [1]. Hedgehog performs alpha-beta apparently using fixed shift magic bitboards incorporating the offset [2], and tunable piece-square tables for knights and king in the endgame derived from center Manhattan-distance [3].
