This is the most common question that comes to people's mind once they think about chess.
According to me, it is not that playing chess will increase the mind level or the IQ level of the player but it helps to bring out whatever the skill and IQ the person is having. So by playing chess it just improves and moulds the skill already present in the person.
But it does not happen once you get into chess for a few months or so but it takes years to mould the mind into a calculating phase. So by continuously working on chess it surely helps you to mould your mind into that strategy kind of thing which actually helps in real life.
