Master your chess openings with Chess Prep Pro: Build and train your opening repertoire.
Chess Prep Pro is the ultimate app for perfecting your chess openings and strengthening your game. It lets you build custom opening repertoires and prepare for any opponent's moves. A chess opening repertoire is a strategic plan outlining your responses to your opponent's opening moves. This prevents game-time scrambling by ensuring you know the best move from prior study and practice.
Key Features:
- Customizable Repertoires: Create unlimited custom opening plans, adding as many moves and variations as needed.
- Repertoire Training: Practice your opening moves with the app's memory training feature. It presents random positions from your repertoire, tracks your progress, and helps you master every move.
- Blind Spot Detection: Identify potential weaknesses in your repertoire. The app analyzes your openings against billions of games to highlight likely opponent moves you haven't prepared for.
- Extensive Player Database: Access a vast database of player moves to anticipate your opponent's strategies.
- Powerful Engine: Leverage the StockFish engine for in-depth analysis and optimal move suggestions.
- Downloadable Repertoires: Access a growing library of pre-made opening repertoires.
- Import/Export Functionality: Easily import and export PGN files, including Lichess studies.

Chess Prep has transformed my opening strategy! The ability to customize my repertoire is a game-changer. However, I wish there were more advanced analysis tools to deepen my understanding of each move.
画面精美,战斗流畅,玩法丰富,是一款不可多得的佳作!
Chess Prep est fantastique pour travailler mes ouvertures. J'apprécie particulièrement la fonctionnalité de construction de répertoire. Cependant, l'interface pourrait être plus intuitive pour les débutants.
