... I want to become a master and ...
There are two relatively recent books about achieving that specific goal:
What It Takes to Become a Chess Master by Andrew Soltis

Reaching the Top?! by Peter Kurzdorfer

I am high class b in rating (1753 USCF) but I am estimated to be class a in strength.
I am looking for what would be the best books for me to improve, I am 14 (almost 15) and have study time and a lot during the summer.
I won't skim the books if they are good, but actually study them.
I already have:
My System
Chess Praxis
New York 1924
Dvoresky's endgame manual
Silmans endgame
Chess strategy for the tournament player
and plan to study those completely first, but what other books are worth buying and studying at my level?
My 60 Memorable games lol?
A great reading which I will postpone. Not worth to go trough the games without time, you will miss some great analysis by Fischer.
I dont know if Zurich1953 by Bronstein would be too hard.
Maybe the Art of the Middle Game (by Keres if I dont remember wrongly) and Art of Attack in chess would be good, I have those ones. The first book is nice as Keres really focuses on defense, which is weird to see in a chessbook.
I know some Professional chess coaches (Robert_New_Alekhine) will kill me for saying this. But MCO 15 is good lol. I usually write the lines down like they taught me in Botvinnik's school to then reproduce it in the chessboard.
Thanks.
About that, Robert_New_Alekhine is my personal coach.
