Chess is nice I used to play, currently Go holds more interest as a hobby/relax game.
You don't need books about chess, unless you like to read for entertainment.
What is needed for any game or self-contained goal is the self-correcting algorithm of action, followed by exploration of possibilities in a leisurely (fun) fashion, so that you can be disciplined when competing and still enjoy what you do when improving and learning.
Practice, but not too much so that you don't develop bad habits and counter optimal strategies, analyse your games, understand what could be done better, so that every game is a learning experience.
Here is a nice "bookish" basic resource
about optimising your methods for learning and practice in a competitive setting.
