Carlsen Used 'Idiot Test' for Chess Prep, Reveals Dubov
Magnus Carlsen, the world's top chess player, had a unique way of testing his new chess moves before big matches.
He'd try them out against a grandmaster, Laurent Fressinet, who wasn't prepared for them.
If Carlsen couldn't win, the new move was scrapped!
Another grandmaster, Daniil Dubov, shared this information.
Dubov also spoke about how competitive Carlsen is and described his training camp experiences.
Daniil Dubov revealed Magnus Carlsen used an 'idiot test' to decide chess opening prep.

Initially, Jon Ludvig Hammer was the 'idiot,' later replaced by Fressinet.
Dubov also discussed team dynamics and Carlsen's competitiveness during training.
