What this is. Each study is a position with one correct path. Your job: find it. Move by move you'll play the white moves, and the app responds with the scripted black replies, with Coach Rayman commentary explaining the why behind every move.

How it works. Pick a study from the list, calculate, and play. If you blunder, you'll see the prose explanation of what was meant to happen. Wrong moves cost nothing — this is for studying, not scoring.

Why bother. Studies build calculation muscle the way nothing else can. Every world champion has worked through them. Spend 10 minutes on one and you'll see ideas you've never seen on a chess board.
