Saul Youssef writes It's after Nash asks his friend (the one who beats him at Go) if he can hang around Princeton. Very minor point, but I suspect the film makers were aware that what Nash would be playing on a go board was the game still known at the Princeton math department in the 60s as the game of "nash". Eventually it became known that John Nash had not been the first to invent it, and the name changed to the now more familiar "hex". Does anyone remember, were the stones in the film on the squares or the intersection lines? (Usually, but not always, the game of nash, unlike go, was played on the squares, it being understood that they were really supposed to be hexagons -- with two diagonal connections besides the two vertical and two horizontal connections.) The film's Nash makes some remark to the effect that he's supposed to win -- clearly Nash should win at nash.
