Shared-board demonstration

In the lesson app: Lesson library → Week 7 demonstration: Skewers.

  1. ♛︎♟︎♚︎♟︎♝︎♟︎♚︎a8b7c6d5e4f3g2h1

    White to move: skewer the king and the queen.

    The pawn on e4 protects the bishop, so the king can’t take it.

    Answer: Bd5+ checks the king; the queen stands behind it on the same diagonal. After the king moves, Bxa8.

  2. ♚︎♜︎♟︎♟︎♜︎♚︎a8b7c6d5e4f3g2h1

    White to move: skewer along the back row.

    Pin: valuable piece BEHIND. Skewer: valuable piece IN FRONT.

    Answer: Ra8+ and then Rxh8.

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 the difference between a pin and a skewer? Answer: In a pin the more valuable piece is behind; in a skewer it is in front and must move.
  2. Why does a skewer often start with a check? Answer: The king must move, so the piece behind it is left undefended.
  3. How do you avoid being skewered? Answer: Keep your king and queen (or rooks) off the same line as an enemy bishop, rook or queen.

Help for beginners

Ask the student to find two enemy pieces on one line with nothing between them, then a square where a piece of theirs can attack along that line.
