Worksheet: Castling, Stalemate, and Draw Basics

Topic: basics | Level: 1

Castling has a few important safety rules, and not every game ends with checkmate — some endings are draws.

Why This Matters

Castling is a special king move: the king moves two squares toward a rook, then that rook hops over it.
You may not castle out of check, through check, or into check, and pieces between the king and rook must be gone.
Some games are drawn: stalemate is the famous one, but insufficient material, threefold repetition, and the 50-move rule matter too.

Write the four castling safety checks you should ask before you castle.
Explain the difference between stalemate and checkmate.
What do these draw words mean in kid-friendly language: stalemate, insufficient material, threefold repetition, and 50-move rule?

Practice 1

White to move. Castle kingside.

Practice 2

Black to move. Castle queenside.

Practice 3

Find the move that stalemates Black right away.

Practice 4

From the same setup, find the move that is checkmate instead of stalemate.

Try castling on both sides. White may not castle kingside through the bishop's attack, but queenside castling is still legal.

Check that the king and rook have not moved, the squares between them are empty, the king is not in check now, and the king does not pass through or land on an attacked square.
Checkmate means the king is in check and cannot escape. Stalemate means the king is not in check, but the side to move has no legal move.
Stalemate: nobody can move. Insufficient material: there is not enough force left to mate. Threefold repetition: the same position happens three times. 50-move rule: fifty moves pass for each side without any pawn move or capture.

Practice 1: O-O — The path is clear, the pieces still have castling rights, and the king is not castling through danger.
Practice 2: O-O-O — Queenside castling is legal here because the rook and king have not moved and the c8-d8 path is clear and safe.
Practice 3: Qd6 — After Qd6, Black is not in check — but Black has no legal move. That is stalemate, so the game is a draw.
Practice 4: Qd8# — Qd8 gives check and leaves Black with no legal escape, so this one is checkmate.
