Zurich 1953 for sure.
Reshevsky's Best Games of Chess. Not well known nowadays, but wonderfully instructive.
Think Like a Grandmaster was a favorite, but it has been replaced by The Inner Game of Chess, by Soltis. Corrects and greatly expands upon Kotov's method of calculation.
Chess Structures: A Grandmaster Guide - Mauricio Flores Rios
