Train

Solve puzzles by theme — forks, pins, mates, endgames — rated to your level, with your own puzzle rating and streaks. Always free, no account needed.

Replay the turning points of your own games and find the move the engine preferred — the highest-value training habit. A few reviews free each week; unlimited on Standard.

Drill a repertoire move by move, with the idea behind each move explained and spaced repetition to keep it sharp. Playing openings stays free; the move-trainer is a Standard feature.

Track every opening you drill — mastery and what’s due for spaced-repetition review in one place. Import your own lines from a PGN or a Lichess study to train your repertoire, not just the book line.

See exactly where you stand: your move quality ranked against players at your level — overall, by phase, by situation, and even how you hold up right after a blunder. The diagnosis that tells you what to fix.

Turns your Skill Profile into a guided plan: spaced-repetition drills on your real weaknesses, banded endgames, thematic play-outs, and a composure habit — with honest proof your mistakes are actually dropping.
