King safety — what it means in chess
How well the king is sheltered from attack.
How well the king is sheltered from attack.
King safety is the first veto in every evaluation: no material count, no beautiful structure, and no strategic masterpiece survives the king getting mated. It is measured in shelter, defenders, and the attacker's access — an intact pawn cover in front of a castled king, defenders within reach, and no open files or diagonals pointed at the royal address.
The shelter pawns are worth more unmoved. Every advance in front of your own king — even useful-looking ones — opens a door that never fully closes, which is why luft is played only when the back rank demands it, and why an attack often begins by provoking exactly one pawn move near the enemy king. The standing patterns of this glossary agree on the address: the Greek gift exists because h7 is the castled king's softest square, and every battery aimed at h7 or h2 is an argument about king safety.
The evaluation cuts both ways in the endgame: with the queens off and the board emptied, the king's cage becomes a liability and the safest king is an active one. Knowing when safety stops being the first question — that is the transition every middlegame player has to learn.
The Endgame Society glossary defines more than 240 chess terms — rules, notation, tactics, strategy, pawn structures, endgames, and openings — in language a beginner can act on rather than dictionary shorthand.
