Chess Repertoire Trainer Free

Contains Ads

This app is designed to help you execute the moves you have selected for your openings. It uses an advanced memorizing technique called "spaced repetition" which focus on your weaknesses.
The app is able to identify the positions for which you are having problems and helps you to correct these weaknesses by using an effective pattern of repetitions.

The concept is very simple and easy to use: you have to select and enter only one move for you own color (your move) and then enter all possible moves of your opponent in response to your move.
Please note this app is not a PGN viewer, it's a training tool. Many apps already exist to explore chess openings variants, but it's not the purpose of this app.
This app will rather help you to execute your opening plan. The perfect execution of this plan will give you a serious advantage against any opponent.

What's New

- Added ECO codes in the openings' list.
- Transpositions: now allows to reach the same position with different move orders (enter 1.f4 d5 2.Nf3 c5, then insert the comment "position 1", then enter 1.f4 c5 2.Nf3 d5, it will display the comment "position 1").
- Now when deleting a move, the whole sub-branch (moves and positions) will also be deleted from the database. This also corrects the calculation of score and coverage statistics.
