Take the challenge
Five positions. Everyone gets the same ones.
Three hard puzzles and two endgames to convert against a defence that plays for the draw. The clock starts when you press start and stops on the server when you finish, so the board ranks you against every other player who solved that position. 3 attempts each; the fastest counts.
The sacrifice
White to play. A piece goes in, and it has to be the right piece.

Rook mate from the centre
King and rook against a king in the middle. Box it in and mate it; the defence plays for the draw.

Bishop and knight
The one every coach says you should know. Drive the king to the right corner before the fifty-move rule saves it.
