Stockfish 16 is currently the most powerful chess engine in the world. The engine's latest version is significantly stronger, winning 12 more game pairs (where each engine plays both sides of the same opening position) as it loses against Stockfish 15.

Stockfish has safely maintained its superiority in the chess engine rankings since 2017. However, on one occasion, a huge upset was caused when another chess engine named AlphaZero had beaten it quite convincingly around the same time.

Only AlphaZero has beaten Stockfish in a match, but humans have beaten Stockfish in individual games, typically by exploiting Stockfish's weaknesses (e.g., extreme time pressure). An example is GM Andrew Tang at hyperbullet time controls (15 seconds) using a weaker version of Stockfish.

Yes, but actually no. The only way to beat stockfish is for it to have some sort of handicap. For example: having a completely winning position on move 1 (via material odds), have a huge time advantage (though you'd probably still lose), or for it to be “dumbed down”.

Stockfish has been one of the best chess engines in the world for several years; it has won all main events of the Top Chess Engine Championship (TCEC) and the Chess.com Computer Chess Championship (CCC) since 2020 and, as of May 2024, is the strongest CPU chess engine in the world with an estimated Elo rating of 3634.

How many moves can Stockfish 15 calculate? ›

Typically Stockfish can search up to 30 to 40 plies (half-moves) deep, which translates to 15 to 20 full moves. This means that it considers all possible moves for both sides up to 15 to 20 moves ahead and evaluates the resulting positions to determine the best move.

AlphaZero won 28 of the 100 games played, while Stockfish 8 won none. The remaining games were drawn. These results were shocking to many in the chess community, as Stockfish 8 had long been considered unbeatable. The games between AlphaZero and Stockfish 8 revealed the strengths and weaknesses of both systems.

Assuming Stockfish level 8 is full strength Stockfish, it's possible to beat it but extremely unlikely. In very rare cases, Stockfish will incorrectly evaluate a complicated position, unless given a minute or two to think. If a human were to get in such a position in a 3 0 game, Stockfish could make a fatal blunder.

Even the best engines today, such as stockfish and AlphaZero, still aren't perfect. They're damn close, but they don't have the 100 percent draw or 100 percent white win ratio one would assume of a perfect game. Is it possible to create a chess engine capable of playing a totally perfect game every time?

We're happy to announce that Stockfish 15 is now available on Chess.com!
