Day 9
The format has two brackets composed of eight players each. The eight-player field competes against each other in knockout style. The double elimination format ensures a second shot at the top for any player who loses a match.
The King‘s Indian Attack is a universal opening: easy to learn, flexible, and rich in both tactical and positional opportunities.
Participants play a two-game classical match followed by rapid tiebreaks if needed. The winners advance in the Championship Bracket, while those who lose their match continue with rapid chess in the Elimination Bracket. Anyone who loses their match in the Elimination Bracket is then eliminated from the tournament.
The classical time control will be game in 90 minutes plus 30-second increments from move one (G/90+30).
The rapid time control will be game in 15 minutes plus 10-second increments from move one (G/15+10).
The playoff time control will be game in 3 minutes plus 2-second increments from move one (G/3+2).
In the Championship Bracket, each match will consist of two classical games.
In the Elimination Bracket, each match will consist of four rapid games.
In the Playoffs, players shall contest a two-game blitz match. If the match ends in a tie, the players shall repeat this process until a winner is determined.
Should match 14 (winner of the Championship Bracket vs. winner of the Elimination Bracket) result in one lost match per player, the two players shall contest a 4-game rapid match (match 15) followed by playoff games (if necessary).
