I think chess may help develop some things that can contribute to intelligence like visualizing, thinking ahead, patience, pattern recognition etc.
But playing chess alone will definitely NOT make anyone intelligent in any kind of useful way in everyday life. You will need to use the skills you develop playing chess to study etc. and only then might chess help you become more intelligent in a way that is useful outside of those 64 squares.
People say playing chess makes you intelligent I am a 1600 but I just started to get really low marks in school the last two tests I really study hard but still no changes any suggestions?
thank you in advance
