Endgame
King activity
In the endgame the king becomes a strong piece and should march toward the action.
With few pieces left, the king is no longer a liability to be hidden — it is a fighting unit roughly as strong as a minor piece, and it belongs in the centre or escorting a passed pawn.
Activating the king a move earlier than the opponent is one of the most reliable ways to win balanced endgames.
Why it matters
Endgames are frequently decided by which king gets to the important squares first.
The mistake everyone makes
Keeping the king tucked away 'for safety' in an endgame where it should be striding into the centre.
