Critic response
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. 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". In an article written by ESPN, Viswanathan Anand spoke about how convenient it was to play online compared to playing over-the-board.
