Wesley So and Hans Niemann lead the Super Rapid & Blitz in Warsaw after six rapid rounds, both sitting at 9/12. Vladimir Fedoseev, the defending champion, trails by a point.

The notable result belongs to Gukesh. He beat Javokhir Sindarov with the black pieces. This matters because Sindarov earned the right to challenge Gukesh for the world title. A loss here, even in rapid, signals trouble before their match.

Gukesh himself is treading water at 50 percent, which is pedestrian for a world champion. He has time to climb the standings with the blitz rounds looming, but this rapid performance won't give him momentum heading into the title match.

Sindarov's struggle is the story so far. The challenger looks shaky. His preparation, his confidence, his form all appear questionable. When Gukesh beats you as Black in rapid, that's not the psychological edge you want before playing 14 classical games for the world title.

So and Niemann continue their strong form in faster formats. Both have made these super rapid tournaments their hunting ground. With blitz to come, either could run away with the event, though Fedoseev will make them work for it.

THE TAKEAWAY: Sindarov's early struggles against Gukesh suggest the world title challenger may arrive at their match underprepared or out of form.
