Mon Aug 18 15:10:00 UTC 2025: ## Chess World Gears Up for 2025 Sinquefield Cup, Biel Highlights Analyzed

**Saint Louis, Missouri** – The Saint Louis Chess Club is set to host the prestigious Sinquefield Cup from August 18th to 28th, 2025, marking the second classical event of the Grand Chess Tour (GCT). Held at the Vue 17 University Club Tower, the tournament will see ten of the world’s top players battle it out in a single round-robin format for a prize pool of $350,000.

The Sinquefield Cup serves as the crucial final leg of the 2025 GCT before the Finals in São Paulo, making it a decisive event for players vying for a spot in the top four. Currently, Maxime Vachier-Lagrave leads the overall standings, followed by Levon Aronian, Alireza Firouzja, and Fabiano Caruana, but their positions remain vulnerable.

Defending champion Alireza Firouzja will face stiff competition from seasoned veterans and rising stars alike. The lineup includes Fabiano Caruana, Wesley So, Levon Aronian, Maxime Vachier-Lagrave, Rameshbabu Praggnanandhaa, Dommaraju Gukesh, and Nodirbek Abdusattorov. Jan-Krzysztof Duda rounds out the full-tour participants, while US Grandmaster Sam Sevian joins as a wildcard.

The tournament will adhere to classical time controls: 90 minutes for the first 40 moves, followed by 30 minutes and a 30-second increment per move thereafter. A tie for first place will be broken by rapid and blitz games, potentially leading to an Armageddon decider.
