Praggnanandhaa opened the 2026 Saint Louis Rapid & Blitz with a dominant performance, racking up 5/6 to seize the lead outright. Sindarov and So sit one point back, already locked in a chase.

The Indian star's start reveals what makes rapid chess so brutal. You can't grind out advantages the way you do in classical. Praggnanandhaa punished his opponents' mistakes immediately and converted chances without hesitation. His preparation was sharp. His execution was cleaner.

The field behind him remains compressed. Sindarov and So are close enough that one good round swings everything. Rapid tournaments punish complacency harder than classical does. A single loss can erase what felt like momentum.

Day one tells you something but not everything. The real test comes when fatigue sets in and the players who've been running hot start facing tougher opposition. Praggnanandhaa has the skill to maintain this pace. He's played at this level before. But Saint Louis always produces surprises when the event enters its second half.

His 5/6 performance gives him room to play for the win rather than defend. That changes the psychological battle entirely. Sindarov and So will need to find a way to create threats before Praggnanandhaa's lead becomes insurmountable.
