An official repository, managed by a volunteer group of core Stockfish developers, was created soon after and currently manages the development of the project. On 18 June 2014 Marco Costalba announced that he had "decided to step down as Stockfish maintainer" and asked that the community create a fork of the current version and continue its development. The last Glaurung version 2.2 was released in December 2008.Īround 2011, Romstad decided to abandon his involvement with Stockfish and preferred to spend his time on his new iOS chess app.

For a while, new ideas and code changes were transferred between the two programs in both directions, until Romstad decided to discontinue Glaurung in favor of Stockfish, which was the more advanced engine at the time.
The first version, Stockfish 1.0 was released in November 2008. He named it Stockfish because it was " produced in Norway and cooked in Italy" (Costalba is an Italian, Romstad is a Norwegian). Four years later, Costalba, inspired by the strong open source engine decided to fork the project. The program originated from Glaurung, an open source chess engine created by Romstad and first released in 2004. The Syzygy tablebase support, previously available in a fork maintained by Ronald de Man, was integrated into Stockfish in 2014. Stockfish supports Chess960, which is one of the features that was inherited from Glaurung. Compared to other engines, it is characterized by its great search depth, due in part to more aggressive pruning and late move reductions. Stockfish implements an advanced alpha-beta search and uses bitboards. The maximum size of its transposition table is 1 TB. Stockfish can use up to 128 CPU cores in multiprocessor systems. It is derived from Glaurung, an open source engine by Romstad. It won the unofficial world computer chess championships in 2013 and was a runner-up in 20. Stockfish is consistently ranked first or near the top of most chess engine rating lists and is the strongest open source chess engine in the world. It is developed by Tord Romstad, Marco Costalba and Joona Kiiski, with many contributions from a community of open source developers.
