Some Chess Innacuracies...
I played competitive chess for years as a kid and young adult.
This is a great film, but there are some inaccuracies as to how chess is really played.
First off, the speed chess the at the Lawrence Fishburn character played in the park is just bad chess. If you try those tactics against a player of any skill, you will get murdered. So the scene where the LF character is coaching Josh to play fast and aggressive is pure nonsense.
Secondly, its very odd that there were so many mistakes made in the final showdown game between Josh and Poe. They could have been nervous, but its hard to believe.
Real chess is tedious, so I see why they had to distort it for the sake of entertainment. The Lawrence Fishburn character was a bit too much.
