역사
1995: Chess.com 도메인은 원래 "체스 멘토"라고 불리는 체스 튜터링 소프트웨어를 판매하기 위해 캘리포니아버클리 소재 회사인 Aficionado에 의해 설립되었다.[2]
2005: Internet entrepreneur Erik Allebest and partner Jarom ("Jay") Severson bought the domain name and assembled a team of software developers to redevelop the site as a chess portal.
2007: The site was relaunched.[1] The site was heavily promoted via social media.
2009: Chess.com announced a takeover of a similar chess social networking site, chesspark.com. Chesspark founders Jack Moffitt and Brian Zisk had moved to work on a web search startup.[3]
October 2013: Chess.com acquired the Amsterdam-based chess news site chessvibes.com, which provided coverage for chess tournaments. It was founded and owned by Dutch chess journalist Peter Doggers in February 2006.[4][5]
2014: The site announced that over a billion live games had been played on the site, including 100 million correspondence games.[6]
June 2017: The 2,147,483,647th (= 231-1) game was played, which caused the iOS app to stop working for those with 32-bit Apple devices. This occurred because of an integer overflow problem whereby the number was too large to be represented in the number of storage bits that were used.[8][9][10]
May 2018: Chess.com announced that it had acquired the 3300+ Elo-rated commercial chess engine Komodo, then ranked 3rd behind Stockfish and Houdini.[11] In conjunction, the Komodo team announced the addition of the probabilistic method of Monte Carlo tree search machine learning, the same methods used by the recent chess projects AlphaZero and Leela Chess Zero.[12]
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.[20] Iranian GM Pouria Darini won the event.[21]
Speed Chess Championships
Chess.com has held five Speed Chess Championships since 2016, all involving 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. Nakamura has won three championships, while Carlsen has won two.[22]
The PRO Chess League was the result of the US Chess League changing its name and format, with faster time controls and a focus on the flexibility of forming and managing teams.[28] Chess.com has hosted the PCL twice starting in 2017, having a regular and a summer series.[29]
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 "Superfinale" 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.[33][34]
In August 2018, the site announced the Chess.com Computer Chess Championship (CCCC, later CCC), a non-stop tournament for chess computers.[35]
Chess.com has hosted PogChamps, an amateur online tournament featuring Twitch streamers, since 2020. The first PogChamps featured notable streamers including xQcOW, moistcr1tikal, Ludwig Ahgren, and forsen. Notable new participants from PogChamps 2 included itsHafu and Hafþór Júlíus Björnsson.[48] PogChamps 3, beginning in February 2021, debuted with a wider range of Internet personalities and celebrities, with new competitors including MrBeast, Neekolul, Myth, Pokimane, actor Rainn Wilson, and rapper Logic.
Features
Chess.com operates a freemium business model: main site features are free but others are limited or unavailable in some respects until a subscription is paid.[49]
Visitors to the site can play on a live chess server and correspondence style games, called "daily chess" on the site. Players may also play against chess engines (computer chess), and participate in what the site calls "vote chess", in which players form teams and vote on the best move. Additional features include tactics training, puzzle rush, chess forums, articles, videos, lessons, chess news, downloads, opening databases, groups, live broadcasts,[50] daily puzzles, team matches, online coaching and a game database of over 2 million games.
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)".[52] It utilizes certain proprietary techniques to catch players using engines in games and bans many on a daily basis.[53][54]
Subsidiary companies
ChessKid.com
Chess.com also runs the subsidiary site chesskid.com for chess players of all ages. ChessKid focuses on a child-friendly environment aimed towards chess improvement for beginners to club players. It also has a guardianship program in which 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.[55] 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.[56][57] According to David Petty, the event organizer in 2013,
“
The online component [of CONIC] makes it unique because, normally, national championships require the players to fly in and stay in the same place. We had to ask special permission for the tournament because it is a rated tournament and there is a much higher chance for cheating.
”
ChessKid has made agreements and partnerships with 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.[55] They also have a long-term partnership with the NTCA (North Texas Chess Academy) which gives children access to online instructors.[58]
