Pawn Dojo

To build your very personal opening repertoire, Pawn Dojo lets you create your opening repertoire as one big tree structure. No limits, branch where you like.

5 killer features that set Pawn Dojo apart from other chess trainers:

• Colored branches: Mark a branch as only for one color, but practice it both ways. Perfect for practicing traps.
• Skill sets: Define subsets of your repertoire to focus practicing. Ideal for preparing a tournament.
• Daily sparring: Practice daily with 10 flash cards of positions in your skill set. Suprisingly difficult!
• Difficulty levels: See your average score of positions at different depths in the game. Master early positions first, then level up!
• Streaks: Keep practicing daily to break your streak record. And get better at chess too.

Pawn Dojo is a fully responsive web application, so it works on all screen sizes.

It's Freemium: you can use all those features with the free version, but have limited Stamina for practice games, but the Stamina regenerates each day. Instant Demo User access: try hassle free everything for 5 days and convert to a real user without losing your data.

Disclaimer: in the future, extra features may be for Pro users only, but the existing functionality remains free. But honestly, only 10 bucks per year, is a steal!
