Grandmaster Praggnanandhaa Rameshbabu dealt Jorden van Foreest his third loss in round four of the 2026 Sinquefield Cup in Saint Louis, while Wesley So maintained his lead at the top of the standings despite a hard-fought draw against Levon Aronian on Thursday, August 14, 2026.
The race at the final regular-season stop of the Grand Chess Tour reached a tense turning point as the elite field crossed the halfway mark of tournament play at the Saint Louis Chess Club. Even so, the day delivered a major shift in the lower half of the leaderboard and kept the pressure firmly on tournament leader Wesley So.
Praggnanandhaa Capitalizes on Van Foreest’s Misstep in Round Four
The lone decisive game in the Sinquefield Cup bracket came when Praggnanandhaa offered an early pawn sacrifice on move eight. Van Foreest accepted the pawn, triggering a chaotic sequence that caught both players off guard.
The position quickly exploded when Black sacrificed his queen. Rather than falling into trouble, Praggnanandhaa maintained absolute control over the board dynamics, noting after the match that the good thing about this position is I can never be worse
after claiming the opponent’s queen. Despite navigating several potential fortress setups from the Dutchman, the young Indian grandmaster successfully converted the material advantage in a queen-versus-rook endgame. When asked about his endgame preparation, he dryly remarked that failing to win such a position would mean I shouldn’t be playing at this level!
The victory moves Praggnanandhaa to half a point behind the tournament leader.
High-Stakes Draws and Tactical Humor at the Board
The remaining matchups on Thursday ended in draws, though several featured intense strategic battles. The marquee fixture pairing Levon Aronian against Wesley So turned into a rigorous Berlin Defense battle. The two grandmasters traded precise moves until the position simplified into a threefold repetition by move 32.
Reflecting on complex lines he calculated during the game but ultimately bypassed, Aronian revealed that his tournament preparation involved strict warnings from his second. Of course I saw Na4, but it seems so ridiculous, if you think about it,
Aronian joked when discussing a fantasy variation. He added that his second, Aryan Tari, had been telling him not to do stupid things, which kept him from playing into overly risky complications.
Meanwhile, Anish Giri secured a steady draw against Javokhir Sindarov, successfully holding an opposite-color bishop endgame a pawn down. Still recovering from a painful round-three loss to Samuel Sevian—which he described as unimaginable
—Giri offered a cormorant take on the realities of elite play: If people would not be losing such positions, I would be out of work very quickly! I think, for the sake of chess, it’s okay that White won that game.
Elsewhere, Maxime Vachier-Lagrave drew against Vincent Keymer by move 35, and Samuel Sevian pushed Fabiano Caruana through the longest endgame of the day before the match inevitably reached a drawing margin.
