Book Move: A move known from established opening theory or an opening database.
In-Depth Explanation
A book move has appeared in recognized analysis or prior games, but that does not make it best for every player or time control. Leaving book simply means the position is less documented. Understanding plans is more useful than maximizing the number of memorized moves.
