This app is the only one on the Android market to calculate your score for each position and then use it for training to target your weaknesses. It's the only application using the spaced repetition concept to learn chess positions from your openings. It's also the only application with a built-in chess engine that helps you find the best moves for your openings.
The concept of this application is to learn only ONE move per position and be prepared for ALL possible responses from your opponent. Your best move is the one that, in your opinion, is the best of all possible moves, from of all possible variations, for a given position. The idea is to always follow familiar paths on known terrain to avoid ending up in an uncomfortable position.
