Most adults are simply NOT interested in chess. End of Story, and this mindless thread? What planet are you guys on? Stop navel gazing and play some chess. Take you mind off this idiot thread.
The OP is trolling, (or too dumb to know better). No more, no less.
True
OP, your friends probably are not studying chess or not serious in chess.
Intelligent is not a major component in chess. It may help to improve a little bit faster, may have + 100 rating bonus. No one cant magically get 1400, or 1600 without dedication.
Also, dont assume yourself less intelligent than others, it will just harm you.
