MyLOA focuses on the part of the game that matters most for your preparation: the opening. Import large batches of games from Lichess or chess.com (Pro), filter them, and analyze only the first moves where your repertoire matters.
- Bulk PGN import from your Lichess export or, with MyLOA Pro, directly from chess.com downloads.
- Flexible filters by time control, rating range, color, or date to focus on the games that match your real training goals.
- Opening-only analysis that stops after a configurable number of moves so resources go into understanding the opening phase, not deep engine searches.
- Performance-aware runs where you can choose smaller batches on older machines or push larger datasets when your hardware can handle it.
For a basic overview of what MyLOA does, you can also visit the Home page How It Works section.
MyLOA groups your games by ECO code and builds compact opening trees, so you can see at a glance which lines you are playing and how they perform.
- ECO-based structure: games are automatically grouped by ECO code so related openings sit next to each other.
- Opening trees: see the most common move sequences you reach from both sides, with frequencies and results for each branch.
- Move ordering by quality: sort candidate moves in each position by how often you played them and by engine evaluation or practical results.
- Concrete scenarios: for example, discover that after 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 you are consistently choosing a weaker sideline instead of the main line.
Beyond simple win rates, MyLOA helps you understand how reliable your openings really are and where your preparation is thin.
- Win rate by opening and color so you can see, for example, that your French Defense scores far better than your Sicilian as Black.
- Critical mistakes by line that highlight where you frequently blunder or drift into inferior positions in your favorite structures.
- Typical positions you reach, revealing when you are avoiding main lines and living in obscure side variations.
- Prioritized study list: focus first on the openings and moves that cost you the most points across your entire database.
Once you know which openings are underperforming, you can decide whether to repair them, replace them, or support them with a dedicated opening book from the Shop.
MyLOA follows a simple, repeatable workflow that you can apply whenever you export new games.
- Import your games: export your games from Lichess (and chess.com with Pro), then load the PGN file into MyLOA.
- Choose filters and depth: select rating range, time control, color, and how many opening moves you want to include.
- Run the analysis: start the run and let MyLOA process your games, building ECO groups and opening trees.
- Review statistics: inspect move frequencies, win rates, and engine evaluations to spot weak spots.
- Update your repertoire: note which lines you want to change and, if useful, support them with an opening book from the Shop.
