'''Stockfish''',<br/>
an [[UCI]] compatible [[:CategotyCategory:Open Source|open source]] chess engine developed by [[Tord Romstad]], [[Marco Costalba]], [[Joona Kiiski]] and [[Gary Linscott]] <ref>[http://www.talkchess.com/forum/viewtopic.php?t=58779 Stockfish 7] by [[Joona Kiiski]], [[CCC]], January 02, 2016</ref>, licensed under the [[Free Software Foundation#GPL|GPL v3.0]]. Marco forked the project from version 2.1 of Tord's engine [[Glaurung]], first announced by Marco in November 8, 2008 <ref>[http://www.talkchess.com/forum/viewtopic.php?t=24675 Stockfish 1.0] by [[Marco Costalba]], [[CCC]], November 02, 2008</ref> , and in early 2009 Joona's [[Smaug]], a further Glaurung 2.2 derivative, was incorporated <ref>[http://www.talkchess.com/forum/viewtopic.php?t=26971&start=1 Re: Smaug: a new chess engine based on glaurung] by [[Marco Costalba]], [[CCC]], March 12, 2009</ref> . Starting out among the top twenty engines, Stockfish has quickly climbed in [[Playing Strength|strength]] to become the world strongest chess entity as of 2018 - at least concerning the [[AlphaZero]] hype <ref>[[David Silver]], [[Thomas Hubert]], [[Julian Schrittwieser]], [[Ioannis Antonoglou]], [[Matthew Lai]], [[Arthur Guez]], [[Marc Lanctot]], [[Laurent Sifre]], [[Dharshan Kumaran]], [[Thore Graepel]], [[Timothy Lillicrap]], [[Karen Simonyan]], [[Demis Hassabis]] ('''2017'''). ''Mastering Chess and Shogi by Self-Play with a General Reinforcement Learning Algorithm''. [https://arxiv.org/abs/1712.01815 arXiv:1712.01815]</ref>, public available chess entity. The name "Stockfish" reflects the ancestry of the engine. Tord is Norwegian and Marco Italian, and there is a long history of [https://en.wikipedia.org/wiki/Stockfish stockfish] trade from Norway to Italy (to Marco's home town of [https://en.wikipedia.org/wiki/Vicenza Vicenza], in fact). Stockfish also referred another famous "little fish", the then strongest chess engine [[Rybka]]. In 2011, Marco Costalba and Joona Kiiski stepped down as Stockfish maintainers <ref>[http://www.talkchess.com/forum/viewtopic.php?t=40610 Stockfish on github] by [[Marco Costalba]], [[CCC]], October 02, 2011</ref>. From that, the project is being developed and maintained by the [[:Category:Stockfish Contributor|Stockfish community]].  A synergy effect with the [[Shogi]] community led to the promising branch of [[Stockfish NNUE]], courtesy of [[Hisayori Noda|Nodchip]], who introduced [[NNUE]] to Stockfish in 2019 <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=2&t=74059 Stockfish NN release (NNUE)] by [[Henk Drost]], [[CCC]], May 31, 2020</ref>.

The release of '''Stockfish 13''' on February 19, 2021, has been triggered by the start of sales of the [[Fat Fritz#Fat Fritz 2|Fat Fritz 2]] engine by [[ChessBase]], based on a recent development version of Stockfish with minor modifications <ref>[https://stockfishchess.org/blog/2021/stockfish-13/ Stockfish 13], The Stockfish Team, February 19, 2021</ref>. '''Stockfish 14''', released on July 02, 2021, further improved due to efforts by [[Tomasz Sobczyk]] and [[Gary Linscott]] in designing a new [[Stockfish NNUE#HalfKA|NNUE architecture]] in conjunction with a [[GPU]] accelerated trainer written in [https://en.wikipedia.org/wiki/PyTorch PyTorch]. Further, the collaboration with the [[Leela Chess Zero]] team payed off, in providing billions of positions to train the new NNUE <ref>[https://stockfishchess.org/blog/2021/stockfish-14/ Stockfish 14], The Stockfish Team, July 02, 2021</ref>. '''Stockfish 16''', released June 30, 2023, removes the classical [[Evaluation|evaluation]] from the engine and focuses on [[NNUE]] neural networks.<ref>[https://github.com/official-stockfish/Stockfish/commit/af110e02ec96cdb46cf84c68252a1da15a902395 GitHub - Stockfish commit, Remove classical evaluation]</ref>
=Science versus Commerce?=
There is a wide range of opinions about strong open source chess engines affecting commercial and competitive interests, as well as monetary interests from computer chess users, who obtain a top engine for free. The scientific and social value of strong open -source programs is indisputable. The [https://en.wikipedia.org/wiki/Teamwork teamwork] effort to share ideas and knowledge to write one of the strongest programs, which everybody may follow and share to learn and play for free, is definitely a challenging and motivating task, gathering both admiration and enviousness. Obviously, professional programmers of commercial chess programs are not that enthusiastic about the development, and need to improve further and/or focus more on secondary features or other business concepts like on-line online play and/or [[GUI|user interface]] issues rather than on pure playing strength. Also, many hobbyist chess programmers feel in the antagonism as well, not only caused by Stockfish with its highly respected authors, and before by [[Fruit]] and slightly [[Crafty]], but from [[Ippolit]] and all its successors by pseudonymous authors and disputed origin. The implications on commercial and competitive computer chess are not quite clear, but presumably, the decrease in the number of participants of over the board [[Tournaments and Matches|tournaments]] will progress and [[:Category:Clone|clone]] suspicions may float like a [https://en.wikipedia.org/wiki/Damocles Sword of Damocles] over the scene, whether programmers took ideas too literally or not.
Also many hobbyist chess =Platforms=Since Stockfish is written in [[Cpp|C++]], it may be compiled and built for various processors and operating systems. The main source code of Stockfish could be compiled directly into [[CLI|Command Line Interface]] program. Some programmers feel in antagonism have added code to change it into a [[GUI|Graphical User Interface]] one which may be compulsory to run on some platforms such as well, not only caused by iOS.==[[CLI|Command Line Interface]]==* Stockfish with its highly respected authorsfor [[Android]], and before by [[FruitLinux]] and slightly , [[CraftyMac OS|macOS]], but from and [[IppolitWindows]] and all its successors was officially built by pseudonymous authors the developer team and disputed originpublished on both [https://stockfishchess.

The Stockfish Testing Framework dubbed '''Fishtest''' <ref>[https://github.com/glinscott/fishtest glinscott/fishtest · GitHub]</ref> is a [https://en.wikipedia.org/wiki/Web_application web application ] written by [[Gary Linscott]] <ref>[http://stockfishchess.org/get-involved/ Get Involved - Stockfish - Powerful Open Source Chess Engine]</ref> <ref>[http://www.talkchess.com/forum/viewtopic.php?t=47885 Fishtest Distributed Testing Framework] by [[Marco Costalba]], [[CCC]], May 01, 2013</ref> and is , based on a [https://en.wikipedia.org/wiki/SETI@home SETI@home] kind of [https://en.wikipedia.org/wiki/Volunteer_computing volunteer computing].
Fishtest is mainly written in [[Python]] under the ''Pyramid Application Development Framework'' <ref>[http://docs.pylonsproject.org/projects/pyramid/en/latest/ The Pyramid Web Framework — The Pyramid Web Framework v1.5]</ref>, and distributes games across different machines to reduce the test latency and increment throughput. Started in early 2013 with Stockfish 3.0, Fishtest has hundreds of contributors, as of June 2018, 1130 testers and 162 developers <ref>[http://tests.stockfishchess.org/users Stockfish Testing Framework - Users]</ref> active in testing ideas and tweaks <ref>[http://tests.stockfishchess.org/tests Stockfish Testing Framework]</ref>, to make Stockfish the strongest chess entity of the world <ref>[http://adamsccpages.blogspot.com/p/sf-framework-history.html Adam's Computer Chess Pages: Stockfish Progression] by [[Adam Hair]]</ref>.

=Tournament Play=
Stockfish is top contender of the prestigious [[TCEC|Thoresen Top Chess Engines Competition (TCEC)]], reaching the superfinals since [[TCEC Season 4|season 4]], and clearly established its world number one status in winning recent TCECs, leaving its commercial rivals [[Komodo]] and [[Houdini]] behind.Since [[TCEC_Season_14#Superfinal|season 14]] in early 2019, Stockfish competes with the [[Deep Learning|deep learning]] [[Leela Chess Zero]] engines, whose [[Playing Strength|playing strength]] triggered a motivation boost in the developing community to further improve Stockfish.
