Norway's Carlsen, the reigning chess, blitz chess and rapid chess world champion, began the online tour at the start of the coronavirus pandemic, which forced the suspension of sport worldwide. 

Chessable Masters is set to be the next event and is scheduled from June 20 to July 5, featuring 12 of the world's best chess players. 

A prize fund of $150,000 (£120,000/€133,000) and a spot in the tour final is available. 

Named after the world’s leading online chess training platform, the tournament will also focus on educating viewers and helping chess fans improve their game. 

"I am proud to announce the next stage in the Magnus Carlsen Chess Tour which I hope will bring something new for spectators and fans," Carlsen said.

"The Chessable Masters will be an elite super-tournament but one in which you can get more involved, have fun, and improve your chess."

Carlsen is set to resume his rivalry with American Hikaru Nakamura, while the winner of the last tournament, Russia’s Daniil Dubov, is set to return. 

Also included is Italian American world number two Fabiano Caruana, China's Ding Liren, Anish Giri of The Netherlands, Teimour Radjabov of Azerbaijan, Maxime Vachier-Lagrave of France and Ian Nepomniachtchi of Russia. 

Three-time world blitz chess champion Alexander Grischuk, reigning European champion Vladislav Artemiev and former Asian individual champion Pentala Harikrishna complete the line-up. 

Harikrishna is the first Indian player to be included on the tour.

"I am excited to be invited to play in Chessable Masters which is also part of Magnus Carlsen Chess Tour," he said.

"I am happy to play against the world's best players in online events during the lockdown.

"I am looking forward to putting on a good show!" 

The first leg of the tour, won by Carlsen, was reportedly one of the most-watched online chess events in history.

Leg two, the Lindores Abbey Rapid Challenge, saw Carlsen knocked out in the semi-finals, as Dubov overcame Nakamura in the final.

It was broadcast live in 10 languages and hit a peak of 125,000 viewers online during the final.
