Very good material. I've heard very good comments from that book, I think I'll start reading it
Stefan Zweig Schachnovelle

Prefer the book, the movie doesn't portray the tension of B's situation that well imo.
On the other hand, Mario Adorf as Czentovic alone is worth watching it.

Didn't saw the movie. Yet.
I saw a recent one Stefan Zweig: Farewell to Europe.
No very entusiastic about it, but neverthless it's about a chess player!

Just read this novel from Stefan Zweig wich i did appreciate very much.
I did have this will to share with the chess community, but as i don´t have to much time as i wanted to write the article, i only share with you some editions covers of the book around the world and some links for whoever is interested in the matter (especially the article by Winter).
