This intelligent pruning is the key to navigating the exponential branching factor of chess. It represents the board using a technique called "bitboards," which use 64-bit integers to map the location of pieces.
Understanding Stockfish Heuristics in Blind Search
Selective Search and Heuristics Blindly searching all moves to the same depth is prohibitively expensive, so Stockfish employs sophisticated selective search algorithms. Its reputation is built on a foundation of deep tactical vision and unwavering accuracy, making it the standard by which other engines are measured.
This allows the engine to perform complex board manipulations and move generation using incredibly fast bitwise operations. It first searches to a shallow depth, then uses the results to inform a slightly deeper search, and so on.

Positional Factors: Detailed metrics for piece mobility, outpost squares, and the potential for creating passed pawns. This fundamental search technique allows the engine to evaluate countless possible moves and their subsequent replies by exploring the game tree.
