Three other “majors” will take place between May and August before the tour ends with a grand finale, which will take place from August 9 to 20.
With much of the sport live due to the coronavirus, the opportunity to make chess a dominant sport is one of the main reasons for launching the tour, says Carlsen.
“The Invitational was a lot of fun and we heard great feedback from players, our broadcast partners and viewers,” said Carlsen, 29, in a statement.
“Although the physical chess and sports tournaments are still canceled or postponed, putting an entire chess tour online is what I think is good for chess now.”
The tour will seek to build on the success of Invitational, which has broken online audience records for chess.
It was the first online chess tournament broadcast on television, broadcast on Spanish, German, Russian, Norwegian and Czech television.
The top four players from the previous competition will automatically qualify for the next “major”.
The grand final will be disputed between the winners of the individual tournaments.
Eight new players will also participate: Wesley So, Alexander Grischuk, Sergey Karjakin, Levon Aronian, Wei Yi, Daniil Dubov, Jan-Krzysztof Duda and Yu Yangyi.
