Stockfish is an open source chess engine, developed by Tord Romstad, Joona Kiiski and Marco Costalba and licensed under the GNU General Public License version 3. The current version 1.9 (as of October 2, 2010) is available as C++ source code, and also has precompiled versions for Microsoft Windows, Linux 32-bit/64-bit and Mac OS X Snow Leopard 64-bit available. The program uses the UCI protocol and can therefore be operated under various graphical interfaces. It can use up to eight CPU cores in multiprocessor systems. The maximum size of the transposition tables is eight gigabytes. Stockfish implements an advanced alpha-beta search and uses bitboards.

In various computer chess rankings Stockfish 1.7.1 is second behind the top commercial program Rybka and just ahead of Naum.

The program originated from another open source program by Romstad named Glaurung. Stockfish was forked from the 2.1 version of Glaurung; the latest Glaurung version 2.2 was released December 2008 but is no longer developed.
