"Must have" books
Logical Chess. You have it on youtube as well: https://www.youtube.com/watch?v=0eTB7oHeRgM&list=PLUrgfsyInqNa1S4i8DsGJwzx1Uhn2AqlT
One book on openings any standard one volume work, one book on middle game eg reassess your chess by silman, one book on endings, eg laszo polgars endgame encyclopedia, one book on combinations eg ECM by informant, these 4 should be sufficient
Botvinnik's 100 selected games is also a good book containing notes on strategic thinking and planning of middle game

Because of the discounts on Book Depository I wanted to buy some books, but I don't know which are the most "worth it" for intermediate player. Could you recommend something? I was thinking about The Life and Games of Mikhail Tal, My 60 Memorable Games, How to reassess your chess and Thinking Inside The Box. Thanks in advance!
