What is the best chess book?
Regardless of level or difficulty.
There are categories within the category of chess book:
chess history
chess art
chess openings
chess tactics
chess strategy
chess analysis
chess biography
chess humor
chess psychology
chess anthropology
Like most chess players I have a small library of unread or skimmed through volumes so I would have to say whatever book you have actually read, worked through, and thoroughly understood.
