Learning objective

Students can recognise a pin (a piece that can’t move, or shouldn’t, because a more valuable piece stands behind it) and use one to win material.

Before class (under 10 minutes)

Prerequisites: Weeks 1–5, especially how bishops, rooks and queens move in lines.

Shared-board demonstration

In the lesson app: Lesson library → Week 6 demonstration: Pins.

  1. ♚︎♞︎♟︎♟︎♜︎♚︎a8b7c6d5e4f3g2h1

    The black knight is pinned: the rook would attack the king if it moved, so it may not move at all.

    A pin to the king is total: the pinned piece cannot move. A pin to the queen is a choice: it can move, but the queen is lost.

  2. ♚︎♛︎♟︎♟︎♝︎♟︎♚︎a8b7c6d5e4f3g2h1

    White to move: pin the queen and win it.

    The pawn on a4 protects b5, so the pinned queen can’t even take the bishop safely.

    Answer: Bb5 pins the queen to the king. Taking the bishop with the queen loses it to the pawn: axb5.

Puzzles on every student’s own board

In class: Puzzles → choose the set → Start puzzles. Each student solves on their own board while you watch every board live. A wrong move gets a reason or a hint (for example “look for a check”), and any checkmate counts as solved.

Check for understanding

  1. What is a pin? Answer: A piece that can’t move (or shouldn’t) because a more valuable piece stands behind it on the same line.
  2. Which pieces can pin? Answer: Bishops, rooks and queens: the pieces that move in long lines.
  3. Can a piece pinned to its king move? Answer: No, never: that would leave the king in check.

Help for beginners

Draw an arrow through the line: attacker → pinned piece → valuable piece behind. If the student is stuck, ask which enemy pieces stand on one line with their king.
