About Chess Prep

Master chess openings: Build chess opening repertoires & memorise your openings.

Chess Prep Pro is the ultimate chess openings app, designed to perfect your openings and elevate your game through custom chess opening repertoire creation and training.

How does it work?

Chess Prep Pro allows you to create your own custom chess openings repertoires, and prepare for any opponent move. A chess opening repertoire is an opening plan that contains player responses for opponent moves in the opening phase of the game. With a chess opening repertoire, you will not be left scrambling to find the best move during a real game, as you will already remember the best move from studying and practicing your repertoire.

Discover Chess Prep Pro's Features:

- Custom Chess Opening Repertoires: Build unlimited custom repertoires for any chess opening. Add as many moves and variations as you need to be prepared for every game.

- Repertoire Training: Sharpen your memory with chess opening repertoire training. The app challenges your memory with random positions from your opening repertoire, tracking your progress and helping you master every move.

- Blind Spot Finder: Stay ahead of your opponents with our blind spot finder feature that analyses your chess openings repertoire against billions of player games, identifying the most likely opponent moves that you did not prepare for.

- Chess openings player database: You can use a player openings database that contains billions of moves to find out the most likely opponent move to prepare for.

- Advanced Engine: Utilize the latest StockFish engine for in-depth analysis and uncover the best responses to any situation on the board.

- Downloadable opening repertoires: Expand your opening knowledge with an ever-growing library of specially created and sourced opening repertoires, curated for your success.

- Import / Export: Easily import and export PGNs to and from the app. You can even import liches studies.
