The BackgammonDB manual

How BackgammonDB works — position tagging, performance rating, and settings explained.

• Getting Started

  Import a match file, browse your library, review a game to find your blunders, and evaluate any decision with the built-in engine — all in the browser, where your matches stay.

• Game Review

  The match-review screen — the board, the action list, candidate moves, performance graphs and stat sheets — and how to drive all of it from the keyboard.

• Position Tagging

  How BackgammonDB automatically classifies every position by phase, structure, and the events of the turn — the engine behind position search and presets.

• Positions Browser

  Search every analyzed position you've ever played — by error, position type, event, phase, roll, opponent and more — using built-in presets or your own saved presets.

• Saved Positions

  Everything you've starred or annotated, gathered in one place and filterable by phase, event, tag, and error size — your personal study set.

• Study Mode

  Turn any set of your positions into spoiler-free flashcards — pick a move, get graded, and drill the ones you get wrong until they stick.

• Match Statistics

  How BackgammonDB measures a match — the equity-loss error bands and their colors, what counts as good vs. best, dice luck, and a link down to Performance Rating.

• Library Statistics

  The /stats page — library-wide performance analytics for your profile. PR over time, PR by match type, outcomes, error-level and cube breakdowns, all driven by a filter bar.

• Database Management

  How profiles decide which side is "you", how to delete matches, and how to back up and restore the whole database to a single file.

• User Settings

  Every preference you can tune — error and blunder thresholds, the joker threshold, equity display, board theme and orientation, and the review layout toggles.

• Create a Position

  The position editor — set up any board, give it dice, a cube, and a score, and watch the engine analyze as you edit. Save the positions worth keeping to a notebook.

• Notebooks

  Named collections of positions you build or collect — each entry with its own score, cube, and engine analysis — and the filmstrip editor that steps through them.
