I am looking for a book recommendation on endgames. More specifically, I want to know how to avoid zugzwang, and what to do in case it arises.
If you know of any book which has in-depth case study on endgames which end up in zugzwang, please give a suggestion.
I don't know any book that has a chapter or even a long section devoted specifically to zugzwang (of course that doesn't mean one doesn't exist) but the concept is pervasive throughout any book about endgames. I think any good endgame book would help; there are books for different levels and tastes, but just to give one example that I have handy, Fundamental Chess Endings by Müller and Lamprecht mentions zugzwang 283 times!
If you are in Zugzwang, by definition, there is nothing you can do, because any possible move leads to a disadvantage.
Most typically Zugzwang appears in endgames with few pieces, particularly in pawn only endgames where is is used as a very common technique. I believe that if you study pawn endgames you should encounter it very often and get very familiar with it, so that you can keep it at the back of your mind when doing calculations.
I would not focus my endgame on avoiding Zugzwang as there are usually other things to take into account as well.
