History


The domain Chess.com was originally set up in 1995 by Aficionado, a company based in Berkeley, California, in order to sell a piece of chess tutoring software called "Chess Mentor".[9] In 2005, internet entrepreneur Erik Allebest and partner Jarom ("Jay") Severson purchased the domain name and assembled a team of software developers to redevelop the site as a chess portal. The site was relaunched in 2007.[5] The site was heavily promoted via social media and grew quickly, attracting mainly casual players.


In 2009, Chess.com announced a takeover of a similar chess social networking site, chesspark.com.[10] Chesspark founders Jack Moffitt and Brian Zisk had already left in 2008 to found the real-time search startup 'Collecta' and were running out of funds for Chesspark. They reached out to Chess.com so as to provide a home for the remaining users.


In October 2013, Chess.com acquired the Amsterdam-based chess news site chessvibes.com, then the number one site for chess news and stories, founded and owned by Dutch chess journalist Peter Doggers in February 2006. Doggers said of the acquisition:







The archive of content from Chessvibes was transferred entirely onto Chess.com's news service and the subscription magazines, ChessVibes Openings (CVO) and ChessVibes Training (CVT), were merged into contributions of the Master's Bulletin. All previous subscribers to CVO and CVT received free premium memberships and subscriptions to the Bulletin.[11][12]


In 2014, the site announced that over a billion live games had been played on the site, including 100 million correspondence games.[13] In June 2017, the 2,147,483,647th game was played, which caused the iOS app to stop working for those with 32-bit Apple devices. This occurred because of an overflow problem whereby the devices were unable to process such a high number, a similar issue that happened to YouTube's Gangnam Style video when it hit 2.14bn views.[14][15][16]


In January 2016, Chess.com announced "v3", the two-year overhaul of its previous interface, which included a slate of new features such as Computer Analysis, Guess the Move, and the variants crazyhouse, three-check, king of the hill, chess960 and bughouse.[17]


In May 2018, Chess.com announced that it had acquired the 3300+ Elo-rated commercial chess engine Komodo, then ranked 3rd behind Stockfish and Houdini.[18] In conjunction, the Komodo team announced the addition of the probabilistic method of Monte Carlo tree search machine-learning, the same methods used by promising recent chess projects AlphaZero and Leela Chess Zero.[19]Chess grandmaster and Komodo co-creator Larry Kaufman said of the merge that







The entire Komodo team joined in the acquirement and are now working together with Chess.com developers and technology.



Tournaments and events


Chess.com regularly holds and sponsors prize tournaments and matches often containing the world's best players.



Death Matches


Death Matches are one of Chess.com's oldest formats, beginning in January 2012, whereby titled players are paid to play a series of blitz games over a non-stop 3-hour period (5-minute, 3-minute and 1-minute, all with a one-second increment).[20] To date, there have been 38 deathmatches, the participants of which include the likes of top grandmasters such as Hikaru Nakamura, Dmitry Andreikin, Maxime Vachier-Lagrave, Lê Quang Liêm, Wesley So, Fabiano Caruana, Judit Polgár and Nigel Short.[21]



US Chess League



The USCL was a nationwide national chess league in the United States between 2005 and 2016. Chess.com started hosting the event in 2013 when USCL commissioner Greg Shahade decided that








Titled Tuesdays


Titled Tuesday is a 10-round Swiss-system 3+2 blitz chess tournament held on the first Tuesday of each month.[22] Many super-grandmasters have participated, such as Magnus Carlsen, Hikaru Nakamura, Maxime Vachier-Lagrave, Alexander Grischuk, Dmitry Andreikin, Wesley So, Fabiano Caruana and it is widely considered one of the strongest online tournaments.[22] The first event was held on October 28, 2014, with a prize fund of $500 and was won by Baadur Jobava.[23] The prize fund was eventually upgraded to $1500.[22] GM Hikaru Nakamura has won the most events with a total of eight tournament wins, followed by GM Georg Meier with seven,[24] Magnus Carlsen has won three of the events in which he has partaken.[25]


In June 2018, Chess.com held a special version of the tournament for which the winner would go on to participate in the Isle of Man International which had a prize fund of £144,000.[26] Iranian GM Pouria Darini won the event.[27]



Speed Chess Championships


Chess.com has held three Speed Chess championships since 2016, all involve a single-elimination tournament featuring some of the world's best players in matches that continue on in the vein of the Death Match format, with the addition of one chess960 game each time control.[28] The speed chess championships have by far the biggest prize fund of any online event.

Computer chess tournament


In November 2017, Chess.com held an open tournament of the ten strongest chess engines with $2,500 in prize money. The top-two engines competed in a "Superfinal" tournament between the two finalists - Stockfish and Houdini. In the 20-game Superfinal, Stockfish won over Houdini with a score 10.5-9.5. Five games were decisive, with 15 ending in a draw. Of the decisive games, three games were won by Stockfish, and two by Houdini.[35][36]



Features


Chess.com operates a freemium business model: main site features are free,[37] but players have to pay to get additional features.


Visitors to the site can play on a live chess server and correspondence style games, referred to on the site as "turn-based". Players may also play against chess engines (computer chess), and participate in voting games, in which players form teams and vote on the best move. Additional features include tactics training, chess forums, articles, chess news, downloads, opening databases, groups, live broadcasts,[38] daily puzzles, team matches, online coaching and a game database of over 2 million games.


The company publishes a large number of articles on a variety of chess-related topics, including chess strategy, opening theory and history. Regular contributors include Gregory Serper, Bruce Pandolfini, Sam Shankland, Dan Heisman, Jeremy Silman, Simon Williams, Daniel Naroditsky, Natalia Pogonina and Daniel Rensch.[39]


Users can play a number of variants on the live server, including crazyhouse, three-check, four-player, king of the hill, chess960 and bughouse.


Chess.com has a policy against the use of chess engines in all forms of the game, except where "specifically permitted (such as a computer tournament)".[40] It utilizes certain undisclosed techniques to catch players using engines in games and bans many on a daily basis.[41][42]



Subsidiary companies



Chesskid.com


Chess.com also runs the subsidiary site chesskid.com for chess players aged 13 and younger. Chesskid focuses on a child-friendly environment aimed towards chess improvement for beginners. It also has a unique guardianship program whereby parents and authorized coaches can overlook the child's progress over time, to see statistics about their progress in tactics or how many videos they watched so that they can give encouragement and tips on how to improve.[2] Chesskid features no advertising.


Chesskid.com has run a yearly online championship called CONIC (the ChessKid Online National Invitational Championship), since 2012 which is recognized by the United States Chess Federation.[43][44] According to David Petty, the event organizer in 2013,







Chesskid have made agreements and partnerships with many chess associations to bring the educational benefit of chess to children in schools. In 2014, for a trial period, all signups to the ICA (Illinois Chess Association) included a free gold member subscription to Chesskid.[2] They also have a long-term partnership with the NCTA (North Texas Chess Academy) which gives children ready access to online instructors.[45]



Gambit.com


In 2013, Chess.com co-founder Jay Severson started a website called Bitnopoly, a Bitcoin version of the board game Monopoly. After seeing that he had a successful business model, he expanded it into a more general Bitcoin gaming website and renamed it gambit.com,[46] which would go on to operate as a sister to Chess.com.[47]


Part of Severson's reason for starting up the company was that he wanted to work with non-skill, yet unbiased games for the purpose of betting, and as such refused to introduce games like Craps, Roulette, Blackjack, Go or Reversi.[47] He has stated that Gambit.com has no interest in featuring chess and that Chess.com has no interest in featuring gambling.[47] Gambit.com involves real-time betting with either wager Bits, Bitcoin bits or virtual points with such games as rock-paper-scissors[48] and Battleship.[47] Players can pay for their Chess.com membership using Gambit funds.
