"It is written for chess players..."
Of course, that is why it was released for sale at the Cannes film festival the real hot-bed of international chess.
You do not pacifically aim a documentary at those who already have an interested or study the topic.

Having watched it a non-player will be able to discuss the incidents without even knowing how the pieces move.
Alan Byron, the director/producer.
I pitched the idea for the film at Cannes in 2015 and as soon as I said the word ‘chess’ you could
see the investors’ eyes starting to close. But once they listened to how the story played, the finance
was literally on the table after two meetings. This is far more than a documentary about chess,

Making a doc just for chess players who are on the whole a frugal lot when it comes to their hobby
would not make financial sense. (pleading for an online link to perhaps watch it for free is a case in point.)

A DVD with Danny King or Andrew Martin on the games is what chess players would seek for a digital fix.

I was comparing the book to the game analysis given in the film, None in the film.
