Stockfish, the world's strongest chess computer, is introduced and its primary features are explained.

• Stockfish is the strongest chess computer in the world.
• It leverages super powerful computers, examining tens of millions of positions per second.
• The evaluation function used by Stockfish is stronger than most chess players in the world.
• Stockfish's ELO, a number that quantifies a player's skill level, is greater than 3500.

The way Stockfish approaches game openings is explained, including its evaluation method and the use of an opening book.

• Stockfish assesses the resulting structures that might evolve from an opening, rather than the opening position itself.
• It uses a giant neural net to learn what's good and bad in an opening.
• Stockfish does not use chess theory or an opening book in the traditional sense.

The method Stockfish uses to navigate middle games is discussed, including its alpha-beta search technique.

• Stockfish navigates the middle game by exploring and ranking all the possible moves.
• It uses an alpha-beta search technique to prune a large number of moves from a position.
• The chess engine searches 50-60 moves into the future to evaluate the best possible move.

The way Stockfish handles end games is explained, including its use of endgame table bases to solve games perfectly.

• In end games, once the number of pieces goes below a certain amount, Stockfish can solve the game perfectly using endgame table bases.
• The endgame table bases allow Stockfish to know the best move in a position, which is either winning, a draw, or losing.
• Stockfish can play without the table bases as well and still play incredibly strong chess.
