I wish it was that easy to define the endgame. John Nunn stated on page 174 of Tactical Chess Endings
, "This looks almost like a middle-game position from an over-the-board encounter. Material is nearly balanced, but in view of the advanced a-pawn White must press his attack with all possible speed."

And there are many more examples. It has less to do with the number of pieces than it does purpose or objective.
