Not a Master (rated 2351 chess.com).
My thoughts?
Chess skills, IQ scores, and life skills all have some degree of overlap; they are not mutually exclusive. But they aren't the same thing, either. Just because somebody has an IQ of 150, that doesn't mean that he'll be a good chess player, or a successful businessman, or a stable husband.
He might, and the high IQ might shift the odds somewhat... but the respective skill sets are so different that it's impossible to make a prediction.
What do I do in real life? I'm retired. I spent 20 years making children's cartoons for television, and more recently worked as a Computer Systems Analyst for the Canadian Military.
So in general, I'm not stupid. I even have a very high IQ.
But when it comes to chess, I simply suck. Even though I enjoy playing it (esp. bullet) and have played quite a few games. Seriously I keep making really stupid moves and sometimes it's just hard to think anything on the board.
I see these top score players who can think and make decisions so so fast, take in what is going on in a split sec and read patterns so well.
And I find myself thinking, "what are these people like in real life?"
They must be geniuses?
If you can spot things, make decisions, make strategic decisions like that in real life,
life would be so easy for master chess players, right?
