Trapped pieces: when a piece runs out of squares
A trapped piece is not captured yet; it just has nowhere safe to go. You win it at your leisure by adding one more attacker.
Most traps come from greed: a bishop takes a poisoned pawn, a knight jumps to the rim, or a queen goes hunting and the escape route closes behind it.

How to spot it
- Count the escape squares of any enemy piece that has strayed into your half.
- Pawn moves are the cheapest way to take squares away.
- Bring an extra attacker only once the escape squares are already covered.

Start the exercisesHow to defend against it
- Before capturing a pawn on the edge, count the retreat squares of the capturing piece.
- Keep at least one safe path home for pieces on the opponent's side of the board.
- If you sense a trap forming, give the piece air immediately, even at the cost of a tempo.
Common mistakes
- Attacking the trapped piece before the escape squares are covered.
- Chasing it with a piece it can simply capture.
Frequently asked questions
- Which piece gets trapped most often?
- The bishop, usually after grabbing a pawn on h2 or h7 that a pawn move then locks in.
- Is a trapped piece always lost?
- No. Sometimes the defender gives back a pawn or finds a counter-threat, so calculate the escape attempt before celebrating.
