The Thrilling Playoffs

After the classical portion, both players finished on 5.5/9. This led to an interesting playoff. The format was simple: 2 Rapid tiebreak games; if the player scored 1.5, they won, but both games ended in a draw, resulting in a final armageddon game. The Rapid games were quick draws, but the Armageddon was very exciting to watch.

The final handshake

The game started with a time control of 5 minutes for White and 4 minutes for Black, with 2 seconds increment from move 61. Praggnanandhaa had white pieces, and he had to win the game to win the title; a draw was enough for Wesley to win his 3rd Sinquefield Cup trophy.

Critical Moment #1

Wesley just played 27...Qc7??, Pragg could have played Ne4! with the idea of Nf6 and winning the exchange, but he missed that.

Critical Moment #2

Black played 44...Re8; Pragg could have played his pawn to h6 here, threatening the g7 mate and forcing blacks queen to stay on the 7th rank to defend it all the time
