Chess Opens: Opening Trainer

Memorizing opening moves is easy to forget. Understanding them sticks. Chess Opens teaches 37 openings for White and Black, move by move, with a short note on why each move is played: what it attacks, what it prepares and what it stops. Then it makes you play the line from memory until you know it cold. LEARN Step through every line one move at a time. A coach's note explains each move in plain English, a red arrow shows what comes next, and you can tap Next, autoplay the line, or make the moves yourself on the board. PRACTICE Play your side of the line from memory while the book replies for your opponent. Get it wrong and the board shakes; get stuck and a hint shows the piece first, then the square. Finish a line with no mistakes and no hints to earn three stars. QUIZ Watch an opening play out and pick its name from four choices. Keep your streak going and see how well you really know your repertoire. EXPLORER Play any moves for either side. The explorer names the opening you've reached, even by transposition, shows which book moves continue from there, and tells you when you've left theory.
