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 discovered attack? Answer: Moving one piece out of the way so that a piece behind it attacks.
  2. Why is a discovered check so strong? Answer: The moving piece can attack something else while the other side deals with the check.
  3. Which pieces can make the attack behind? Answer: Bishops, rooks and queens.

Help for beginners

Ask: “Which of your pieces is standing in front of your rook, bishop or queen? Where can it go with a threat?”
