Okay. But it isn't much useful either. Let's halt on this one.
What if I say studying Paul Keres or Salo Flohr's isn't going to help me?
If you say that, either you are already IM/GM level or you haven't studied their games. Even GMs still study the games of Flohr and Keres. Sure, they have better things to do with their time, but I'd wager that most GMs have studied at least a few games and studies created by Keres. And even more have played or studied openings created by Keres.
What if I say I've just spitted out my beer and it's all your fault?!
