The Professional Rapid Online Chess League (PRO Chess League and abbreviated PCL) is an online rapid chess league operated by chess.com. It was preceded by the United States Chess League, which announced in 2016 that it would be renamed, reformatted, and opened to cities from around the world, and moved to the website chess.com.[1][2]

In its inaugural season, the PCL comprised 48 teams, whose members included some of the highest-rated chess players in the world, including the reigning world champion Magnus Carlsen, and other elite players including Maxime Vachier-Lagrave, Hikaru Nakamura, and Wesley So plus over 100 other grandmasters.[3] The 48 teams represent cities in five continents.[3][4]

2018[edit]

The 2018 season began on January 17 and ended on April 8 with the Armenia Eagles defeating the Chengdu Pandas to claim their first title.[10]

Qualification[edit]

In order to combat the large league, Shahade decided to cut the league from 48 teams to 32 teams as he believed the inaugural season was "a bit to large and chaotic".In order to determine which teams would return, he used the following:[11][12][13]

  • 24 teams invited
  • 6 teams per Qualifier Tournament
  • 2 teams per fan vote

Qualification Tournament[edit]

The Qualification Tournament started on October 28 with the Early Qualifier for teams located in Europe, Africa, and Western Asia. The Late Qualifier were for teams in North & South America and Southeast Asia. The event format was as stated:[14]

  • 15 round individual Swiss using time format of 3|2
  • If you play with another teammate during tournament, you'll be guaranteed one point from the game
  • Scores determined by adding sum of scores from all four team members
  • Top 3 teams from each qualifying tournament automatically qualify for PCL

Super Saturday & Super Sunday[edit]

For 2018, the PCL introduced a new match format which allowed teams to play outside of their division. In these matches, each team will play one single four game match against eight other teams on Saturday and then do it with different teams on Sunday. Once every team has played sixteen other teams, the total match points will be added up. The following prizes were given:[15][16]

  • 1st: 1 match win + $500
  • 2nd-6th: 1 match win
  • 7th-10th: 1 match draw
  • 11th-16th: 1 match loss

Critic Response[edit]

Supporters say the league's worldwide distribution, the prize money, and the participation of many of the world's top-rated players may create a new level of competition and awareness for the game. It is anticipated that the new formats are leading to a "rise in popularity of online and rapid chess". In addition, the PCL has the potential to dramatically change chess culture and could lead to corporate sponsorships. This change from an "individual and slow game," to a relatively quick and team format, has made the offering more viewer friendly.[4]

In a 2017 article, Greg Shahade made a similar statement to what Eric Rosen mentioned. Shahade talked about the league featuring worldwide team competition, using the scheveningen system which gives lower rated players the chance to pull upset each week, and having the chance to "revolutionize chess".[25][26]

In an article written by ESPN, Viswanathan Anand spoked about how convenient it was to play online compared to playing over-the-board.[27]
