Nimzowitsch was older than Alekhine. Some early games between the two,
were played when Alekhine was 13 years old.

Petrosyan and others were influenced by Nimzowitsch.

A book not by Nimzowitsch which every player should have in a collection is Pawn Power by Hans Kmoch. Some copies are available at Campus!.com.
