There is no relation, I have tested up to 160, usually around 150:
The relationship between intelligence and wining
Sort:
I think I read this in Anders Ericsson's book "Peak", that players with the highest IQs did better at first than those with lesser scores. But the higher IQ players didn't work as hard and were passed up by those that did. Bottom line is that nobody gets really great without lots of deliberate practice.
Opponent 1 vs Opponent 2, who wins is smarter, and that's what people think about playing chess, but chess is all about practicing and studying the moves and paying more attention.
I scored with the international IQ test around 130-135, and i still lose a lot of matches.
In the end i knew my fault, i was trying to kill as much as i can, ignoring the fact that i should "Checkmate" the opponent, or even secure my King's position, you see, people think differently.
I also won a lot of matches by luck, or wining without thinking about that plan in the first place, sometimes it just come for you like that, you win with one move, by a fault from the player, or by thinking about a plan that didn't work, but suddenly you see that you can win by a move.
You need to know that chess contain a lot of possibilities, you cant predict a lot of moves, only super computers can.
I was a fool for judging my "Intelligence" by a game or by a stupid test i took, so you shouldn't underestimate yourself and hate the game, go practice and enjoy it!
I hope i cleared the big picture, and have a nice day.
