That's a point, but not completely true. Noobs make a lot of errors, intermediate players may miss some tactics or mates but really good players may miss a really complicated tactic or a mate in 10.

They'd never lose a game against me if I had two hours and they have 5 minutes, even if they wouldn't be able to think when my clock is ticking.


But I agree, if you want to play "pure" chess you have to play longer time controls
