King safety

You might say: king security, king shelter

How protected a king is from checks, mating threats, and lines opened against its shelter.

What it does
Sets the urgency of attack, defense, and simplification: an unsafe king can outweigh a material or space advantage.
Ask
Which king is easier to attack, and which line, defender, or pawn move changes that answer?
Typical
Safe or exposed; castled or uncastled; intact or weakened shelter; closed or open lines.
Trouble
An exposed king, missing defenders, or a weakened shelter that lets the opponent force checks or mate.

What to look for

  1. Castled or uncastled king
  2. Intact or weakened shelter
  3. Open lines against the king
