What is the algorithm for Stockfish?

Stockfish uses a calculation method known as minimax. In the minimax algorithm, Stockfish considers a set of potential strategies (current moves which can be played) and the best strategies that can be utilized by the opponent as a response to each strategy.

How does Stockfish search so deep?

Stockfish takes a wide tree of possibilities and gives them a very basic evaluation. It then prunes (cuts off) those moves that get a bad score, and continues to look deeper into the remaining moves. The process continues until Stockfish manages to reduce down to a few best options.

How does Stockfish work so fast?

The Main one is its aggressive Alpha Beta pruning and late move reductions. To explain a bit further. AB Pruning is a search algorithm which basically cuts out the number of nodes in its search tree. How it works is it stops evaluating when it determines and proves the move to be worse than another examined moves.

What level should beginners be in Stockfish?

I would like to recommend a beginner level for stockfish. Level 1 and 2 one can blunder pieces and could get away with this without punishment.
