Shared-board demonstration

In the lesson app: Lesson library → Week 12 demonstration: Must-know endgames.

  1. ♚︎♛︎♚︎a8b7c6d5e4f3g2h1

    King and queen against king: push the king to the edge and checkmate it. Watch out for stalemate!

    Make a box with the queen a knight’s jump from the king, shrink it, then bring your king.

  2. ♚︎♜︎♚︎a8b7c6d5e4f3g2h1

    King and rook against king: make the box smaller with the rook, bring your king, then mate on the edge.

    The rook cuts the board; the king helps; mate comes on the edge.

  3. ♚︎♚︎♟︎a8b7c6d5e4f3g2h1

    King and pawn: with the king in front of its pawn on the 6th row, White wins. (Coach plays it out: Kd6 or Kf6.)

    The king leads, the pawn follows.

  4. ♚︎♟︎♚︎a8b7c6d5e4f3g2h1

    The square of the pawn: draw a square from the a-pawn to the first row. If the white king can step into it, it catches the pawn.

    Here Ke2 steps into the square (a5–e5–e1–a1) and the king catches the pawn: Ke2 a4 Kd3 a3 Kc2 a2 Kb2.

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 stalemate? Answer: The side to move has no legal move but is not in check: the game is a draw.
  2. Where does a lone king get checkmated? Answer: On the edge of the board.
  3. Why does the winning king have to help? Answer: A queen or rook alone can’t cover all the squares next to the enemy king.

Help for beginners

Use the shared board for king and queen against king, one student moving the queen, another the black king. Stop before each queen move and ask: “Is it stalemate?”

For stronger students

"Week 12 harder": the stalemate trap for Black, then play king and queen against king against the coach.
