I have a new interest in chess this year and I am following the games on you tube of all the gems of chess. One thing that used to puzzle me was the way they must be thinking at the time when there were no computer engines or analysis tools. So I thought the movie would be a about a girl who is brilliant in chess and how she thinks from a kid brain to and adult experienced player. But the movie is a bout a journey of a girl and her passion for the game which is very well shown.
