The time control is 100 minutes for the first 40 moves, 50 minutes for the next 20 moves, and then 15 minutes for the rest of the game, plus a 30-second increment per move starting from move 1.

If there is a tie for first place, tie-breaks take the following format:

 

Players play two rapid chess games at 15 minutes plus 10 seconds per move. In the case of a three-way to six-way tie, a single round-robin is played. If seven or eight players are tied, a single round-robin is played with a time limit of 10 minutes plus 5 seconds per move.

If any players are still tied for first after the rapid chess games, they play two blitz chess games at 3 minutes plus 2 seconds per move. In the case of more than two players tied, a single round-robin is played.

If any players are still tied for first after those blitz chess games, the remaining players play a knock-out blitz tournament at the same time control. In each mini-match of the knock-out tournament, the first player to win a game wins the mini-match.
 

 

Eight players compete in a double round-robin tournament (14 rounds), with 4 rest days, a final tiebreak in case of a draw, and a €500,000 prize pool.
