Stockfish

Download Stockfish

Note: Stockfish is a command line program. You may want to use it in your own UCI-compatible chess GUI.
Developers should communicate with Stockfish via the UCI protocol.

Get started

First download Stockfish. Stockfish itself is completely free with all its options.
Next, download a GUI (Graphical User Interface) as it is needed to conveniently use Stockfish. There are multiple free and commercial GUIs available. Different GUI's have more or less advanced features, for example, an opening explorer or automatic game analysis.
Now Stockfish must be made available to the GUI. Install in a Chess GUI explains how this can be done for some of them. If a different GUI is used, please read the GUI's manual.
Ultimately, change the default settings of Stockfish to get the best possible analysis.
