Replay Chess

Replay Chess is designed for avid players looking to take their chess learning to the next level. Build a personalised database of annotated openings and custom puzzles, and reinforce your learning with just a few minutes of daily practice. Whether you're exploring new or complex opening lines, correcting mistakes from your games, or mastering tricky tactics, Replay Chess makes studying chess convenient and efficient!

CORE FEATURES
- Automatically save moves to your personal database of game trees.
- Easily navigate through the game tree using intuitive arrow buttons.
- Effortlessly edit and delete moves by tapping and holding badge icons.
- Write comments, explanations, or hints in any position using the info button, allowing for deeper analysis and improved searchability.
- Press the play button to start a puzzle-like practice session. Your opponent's moves are automatically played from the game tree, and your goal is to respond with moves previously marked as correct.

CUSTOM PUZZLES:
Create standalone chess puzzles from any position. Perfect for correcting mistakes from your past games. Puzzles use a three-strike system that adjusts the day in which the puzzle is rescheduled for, optimising learning so that over time your toughest puzzles will be shown most frequently:
- Zero strikes, doubles the scheduled interval.
- One strike, has no effect on the interval.
- Two strikes, halves the interval.
- Three strikes, resets the interval to one day.

ADVANCED SEARCH:
Effortlessly search through your entire database for any comment, move, or position. Replay Chess uses a one of a kind, powerful token-based search system that allows you to input combinations of pieces and squares to construct queries. For example:
- Enter "Pe4" and "pc5" to find positions with the Sicilian pawn structure.
- Enter "Ke1", "Kg1", "Rh1", "Rf1" to search for white kingside castling moves.
- Enter "qb6" to search for moves or positions that contain a black queen on the b6 square.

PERSONALISATION:
Make Replay Chess truly yours. Customise your chess board, pieces, and badges with colours of your choosing to match your style and preferences.
