Selective Search and Heuristics Blindly searching all moves to the same depth is prohibitively expensive, so Stockfish employs sophisticated selective search algorithms. Moves that are obviously bad are pruned early, while quiet, positional moves are explored with less depth unless the position demands otherwise.

It uses heuristics to identify the most promising lines of play, focusing the majority of its computational power on variations that are likely to be critical. The Core Engine: Alpha-Beta Search and Beyond At the heart of Stockfish lies a highly optimized implementation of the minimax algorithm, enhanced with alpha-beta pruning.
Furthermore, it utilizes "magic bitboards" to calculate sliding piece attacks (rooks, bishops, and queens) with remarkable speed, often in a single CPU instruction. Its reputation is built on a foundation of deep tactical vision and unwavering accuracy, making it the standard by which other engines are measured.
