World Chess Champion Magnus Carlsen is back for the 16-player Aimchess US Rapid, the 9th and last event on the $1.6 million Meltwater Champions Chess Tour before the Final. It runs from August 28 to September 5 on chess24.

The 3-day preliminary stage sees the players face each other once before the bottom 8 are eliminated while the top 8 advance to a knockout consisting of 2-day matches. The time control is 15 minutes for all moves, with a 10-second increment per move from move 1. The knockout match-ups consist of 4-game matches on the first two days. If the match score is 1:1, two 5+3 games are then played followed, if needed, by Armageddon, where White has 5 minutes to Black’s 4 but a draw counts as a win for Black.
