It's said that it was Humphrey Bogart who introduced in detail a game chess, that it can be seen in the film Casablanca.

 Watch part of the film (2 min 52’’)

In this scene, it is shown Bogart in the  Rick Café playing against himself. He is in the black side and it’s turn to throw the white ones than move Nb5. It’s about of the position as a result a variant of the French Defense, attak Chatard-Alekhine: 

1.e4,e6  2.d4,d5  3.Nc3,Nf6  4.Bg5,Be7  5.e5,Nfd7  6.h4,c5  7.Bxe7,Qxe7  8.Nb5

  Position after 8.Nb5

In all the scene it’s only shown the movement 8. Nb5 because of this Bogart reflects. A little after of this movement, the door is open and an individual –certain Ugarte- appears, who wander off the subject. But in certain way, Humphrey have an eye on the tense game all the time. A fight from the “French side” of the chess  a difficult position but with a lot of possibilities. That is related with the identity and the profile of the character of the film.


Moment of the film when it is possible to see the knight in b5

It can also be seen that at the end of scenne Bogart touchs the black king, but at the end he does not move it. If he had to follow the rule of  piece touched it’s supposed he would have moved 8…,Kd8 protecting c7 or  8...,0-0 sacrificing the tower in change for a lot of central pawns.
