Factual error "Where is the bishop?"

Rating: 4/10 (29 April 2016)

In Game 1: (Fischer's last move scene)
we can see the white bishop.
oh wait wait, second camera angle the bishop disappeared.
And the third scene still we cant't see the white bishop.
And at the end the magnificent white bishop finally appeared.
Do you think the director,stars and the other cast really know playing chess.
Near the start young Bobby is looking out of his bedroom window, the date on screen reads 15th Nov. 1951. Bobby goes from his bedroom to see his mother and tells her there's a red 1952 Chevy outside.
