What you get

Click, drag, paint

Pick a piece and click or drag across squares to place it. Right-click empties a square; drag a piece off to remove it.

Legal, or why not

It says what’s wrong: a missing king, pawns on the back rank, the side not to move in check.

Side to move and castling

Choose who’s to move, and only the castling rights the king and rook allow.

Six strengths

Beginner, Casual, Intermediate, Advanced, Expert and Maximum.

Watch or play

Stockfish against itself (slow, normal or fast), or against you, with its lines hidden and a Take back button.
