Process

King activity

You might say: active king, king route

King activity is the deliberate use of the king as an endgame piece: approach pawns, occupy key squares, support a passer, or cut off the enemy king. The king should remain safe while the position still contains tactical mating or checking danger.

What it does

Converts king proximity and tempo into opposition, pawn support, blockade, or promotion gains.

Ask

When is the king safe to activate, and which route reaches the decisive square first?

Trouble

The king enters too late, or walks into checks and tactics before the position is ready.

What to look for

1. King approaching pawns
2. King on a key square
3. King supporting a passer
4. Enemy king cut off
