A little about the app Chess Repertoire Trainer Free

In chess, a winning game starts with the very first move. It doesn't matter how creative you may be in the middle game or endgame if you lose the opening. Your goal while playing the opening should be to reach a familiar and comfortable position. This is what this app is all about.

This app will help you define a complete chess opening plan and will train you to execute it. It will also allow you to define mid-games or end games if you also want to train on these aspects of the game. The app uses an proven memorizing technique called "spaced repetition" which focus on your weaknesses. It continuously identifies moves that give you more challenge and helps you to improve by using an effective pattern of repetitions. The perfect execution of the plan you prepared will give you a serious advantage against any opponent.

The concept is very simple and easy to use: you select and enter only one move for your own color (your best move) and then you enter all possible opponent's moves in response to your move.
