1. Round 1 - the first pairs will be randomized by the league system (simultaneously randomizing groups); after the 1st round, regardless of the battle result, no one leaves the tournament.
2. Round 2 - the winners of the first round in their groups play against each other for a better position in the next round; the losers of the first round in their groups play against each other for their standing in the tournament (losing means the end of the competition for these players). A player who wins 2 rounds takes 1st place and does not need to fight in the 3rd round; they just wait for the 2nd stage (2-week break).
3. Round 3 - only for players who already have a 1/1 (win/loss) record. This is the last chance for the 2nd stage; the winners advance, and the losers are out of the tournament.
