What Is Stockfish?

Stockfish is a chess open-source UCI (Universal Chess Interface) engine that plays chess without a graphical interface to provide speed and ease of access for both programmers and end-users. Marco Costalba, Joona Kiiski, Gary Linscott, and other contributors developed Stockfish. The project started in late 2008 and was released to the general public in late 2009. Stockfish has ranked highly on the CCRL, CEGT, Fishtest, and other computer elo rating lists, where it faces off against other chess engines by the use of self-play AI.

Since March 2011, nearly all of Stockfish has been licenced under the GNU General Public License v3 (GPLv3). This allows users to work with the engine and incorporate it in other applications. It is, for instance, used as the default engine in the chess platforms Lichess (except in Titled Arenas), Chess.com, Winboard, Lucas Chess, and countless other online and offline chess installations. Gary Linscott continues to be the primary organizational and development leader.

How Does Stockfish Work?

Stockfish is a UCCI or UCI-only (Universal Chess Interface) binary. It reads a specific protocol called a FEN (Forsyth–Edwards Notation) string consisting of 6 blank-separated fields which represent the state of a chess game in terms of the position of the pieces on the board, capture flags, side to move, castling availability, en passant target square, and halfmove clock.

A FEN string is linked to an EPD (Extended Position Description) that gives all available legal moves (along or ordered pairs of letters and digits) in the current position. Actions that started the game, such as checks, checkmates, or draws, are reflected in the FEN information. Chess engines keep a set of tables linked to bitmaps that represent every object and action in the game. These are used to quickly calculate all valid alternatives, and pick a best move to play.

How to Download and Install Stockfish?

You download Stockfish from the official Stockfish GitHub page https://github.com/official-stockfish/Stockfish/releases.

After following that link, select the version of Stockfish to download. As of 18 July 2021, the most recent is Stockfish 14 for Windows, macOS, Linux, Debian, iOS, Android, Raspbian, Plus Calibrated, Plus SfBench, Plus with NNUE, GTCP, SugaR, LcZero, Arasan, Corchess, Pedone, Senpai, Cfish, and Booot.

Find the corresponding zip download and unpack it. On Windows, the most recommended version on the GitHub page is `stockfish_14_win64.zip` for 64-bit devices. There are no installation or setup requirements. Stockfish is already operational after unpacking the zip file and launching `stockfish_14_x64.exe`. If guidelines such as running the binary via the command line confuse you, you can also drag and drop the `stockffish_14_x64.exe` file onto `cmd.exe`. Stockfish should write its version in the `cmd.exe` console if it was properly drag and dropped. Any version of Stockfish after 9 will work on macOS and start performing proper operations immediately after unpacking. The initial parameter setting is for ideal performance even though some players might prefer to change it. There is abundant documentation from the Stockfish team on the `Stockfish Programming Wiki` if any player wants to learn more about potential parameter changes.

Real-time Analysis

Stockfish real-time analysis is a Premium-only feature from Chess.com. With this enabled, play against any live opponent with Stockfish running moves live. The analysis is provided in real-time and calculates processes for around 50,000-250,000 positions per second. They give a +3 advantage for Stockfish real-time analysis for white arrocha, but it looks as if the commander in this game from Rio de Janeiro has gotten back on top against his new opponent.

News18 helps people understand the mechanisms of analysis that Stockfish uses to calculate moves. It analyses the best move for all units live and pulls the results from 4 to 6 processing algorithms open source documents known as “chesses wiki.” Chesses wiki calculates the probability distributions of moves and provides an exact mathematical formula for the engine to analyze the game in real time. Stockfish has been rated at Elo 3397 and is one of the best chess engines available, but using Stockfish in real-time analysis on Chess.com is not indicative of the movement’s current capacities. However, it is instructive for understanding effective chess strategy strategies, particularly for more complex positions or when planning your chess move live.

Watch the following video from the Chess.com YouTube Channel of Sam Copeland talking about using real-time analysis on Chess.com.

Multiple Variations

In their core, staples offer only one line, so they are not well-suited for multiple variations of the same type of chess opening. However, if the same opening line occurs in different chess openings, one can access higher-level variations as long as the branch open is followed by the new type of initial setup. Chess.com provides only one variation of the backbone of the Winnawer line during the Advanced Variation after the move up to the Knight of 7 squares. The second move is usually to g3, but in a game with the same initial positions, the game move was Kg2. If that happens, Stockfish will respond with Bg4, h4. The subsequent real openings in the second move of the top 9 moves are Reifenstahl gambit, Bb5 check, but Stockfish does not vary from the main line medium confidence opening.

Stockfish is for the most part a backup coach to the opening book. When in doubt, players using Stockfish will default to the digital assistant’s position suggestions. The idea is to add a strong, high-speed assistant to the regular chess.com’s experience without reducing its depth. In many lines, Chess.com analyzes past rated games and its own engine DeepDiamond to provide suffusion data analysis. Stockfish is meant to reinforce or challenge these conclusions, as a worthy elder assistant for those who wish to see more position options.

Depth and Time Settings

Active Parameters Preset only has the Stockfish Depth set to go up to 16 levels but the app for the Stockfish engine itself has levels going up to 60 as one would expect of the world’s strongest publicly available chess engine. Adjust the Depth of the analysis so that you remember the important ideas. During my game, I will typically let the analysis engine run to about Depth 25. I can get some idea of long-term strategy from that. But running the engine all the way up to however many levels it can is the best if I want to make sure we give an evaluation at the end of the game.

Leave the Minimum thinking time for Stockfish at zero. Timer settings on the club and regular analysis should have longer minimum thinking times for Stockfish. But if I want to cycle through suggestions of what the Stockfish engine things are the best moves for me the zero value for minimum thinking time will dispense its popular answers. I would rather build my own understanding.

Position Evaluation

What is Stockfish Chess and where is Stockfish in chess.com? Position evaluation is where Stockfish screen shows moves, and explanations behind those moves while it is analyzing. While the instructions for seeing Stockfish analysis on Chess.com’s website have not been released as of April 2022, according to positions from older versions, after starting the analysis of a game, the Stockfish popup can be viewed by clicking on the new Tab button and provided that Stockfish does not give an error message.

How Can Stockfish Improve Your Chess Skills?

Stockfish can improve chess skills by being used to provide nuanced post-play analysis. Stockfish will identify moves that are not the most optimal, find better moves or alternative lines, and identify where the turning points in play intersect. These are key markers during study to determine how a match was won or lost, as well as for identifying areas of a player’s game that need improvement.

Identify Mistakes

To use Stockfish on Chess.com to identify mistakes, replay a game at the move you want to analyze. Click on the Analysis tab below the board. This will cause the Chess Analysis pane to appear. Click the Modify settings button to change your chess engine, then press the Play button to see who Stockfish recommends to have an advantage in the position.

Learn New Strategies

Stockfish is useful for learning new strategies in every phase of the game. Chess is a complex and dynamic game in which strategies and themes change with each move. Watching the Stockfish Engine Analysis Panel helps players view and asses the changes.

The following are examples of how players can use Stockfish analysis to learn new strategies during different phases of the game:

1. Opening: Utilize key squares, castle early on, and open lines for developmental pieces.
2. Middlegame: Regroup your pieces to advantageous positions, deny your opponent space, and perform a pawn break.
3. Endgame: Have king position in mind, study opposition positions, avoid time-wasting stalemates.

Analyze Opponent’s Moves

Chess.com allows you to play with players of different skills and play chess with a computer at different difficulties. At beginner to intermediate levels, you have to analyze your own moves rather quickly during the game while relying on blunder and inaccuracy checks on Chess.com and only afterwards on Stockfish analysis.

At an intermediate to expert level you are able to freeze the game and run stockfish analysis to help you make strategic in-game moves more because both you and your opponent are making better tactical moves.

Improve Calculation and Evaluation Skills

Improving calculation and evaluation skills can only be accomplished by playing games. An expansion of the evaluation skill of positional understanding can be improved by consulting a stockfish chess engine’s analysis after the game to find out in which positions the computer was evaluating you or your opponents’ position as stronger or weaker.

Improving calculation can be done by setting easier problems first, as stockfish will assist by showing its moves in perfect solutions. Hannah Pover, a sophomore at Asheville School in the US and a competitive club chess player, describes her approach to using stockfish to improve her calculation by recommending GFTPM’s YouTube channel. She offers tacit confidence in calculations and solving mate problems using a stockfish engine.
