In a sense, chess is completely about intelligence and anyone saying such a statement is untrue doesn't know what chess is and what intelligence is.
I think that I and people who are in agreement with my views have been insufficiently proactive in putting forward our views. It may, however, take a certain amount of intelligence to understand why our views cannot be anything other than correct. It shouldn't but one can't speak for the unintelligent.
I think when people disagree so strongly about something, then they aren't talking about the same thing. Earlier in the thread, you gave what I think is a great definition of what intelligence is. I think that other people have either a different idea of what it is, or a very fuzzy idea about what intelligence is.
If everybody understood "intelligence" to mean the same thing, then I don't think there would be a lot of disagreement.
That's an optimistic viewpoint and, by the way, thanks for the commendation.
However, if people can't understand what intelligence is, their viewpoints are of little interest. I would say that some people, who have a reputation here for being very clever and so forth, seem incapable of discussing abstract problems in such a way that they can show they understand viewpoints they're arguing against. Arguing past each other is very prevalent, even with people whom many assume can think well. When you have out and out trolls who are actually respected by some people, then they are capable of knocking any discussion off course simply by bringing their supporters to the meeting. Until others are mature enough to ignore them or tell them to go away, conversations here will remain childish.
So yes, a lot of people imagine that intelligence is some invented thing which bears no relation to reality, rather than an attempted measure of intellectual capacity to understand and use reality, which is basically our environment.
So no, optimissed you may have played chess for a long time, but sadly you're not smarter than you were before, you just wasted time but at least you're just better at chess.
I mean dont expect that because you play chess now you will be an astropjhysicst or you will be capable of solve any kind of problems. If chess indeed will be a measure of intelligence also Magnus Carlsen or kasparov would be the smartest person in the world.. and of course they are not haha.
