Chess Virtuoso

Chess Virtuoso is the smartest way to learn and memorize chess openings. Whether you're a beginner looking to stop blundering on move 5, or an experienced player drilling deep theory, Chess Virtuoso adapts to your level with a proven spaced-repetition system. ◆ HOW IT WORKS Play each opening move by move on an interactive board. The app scores your performance and schedules each line for review at exactly the right moment — using the SM-2 algorithm, the same method trusted by top memory tools. Study less, remember more. ◆ YOUR DAILY SESSION Every day, Chess Virtuoso prepares one short session that mixes the openings due for review, rated puzzles and Guess the Eval positions. One tap, a few minutes, and every part of your game gets trained. ◆ 300+ OPENINGS Explore a curated library of official openings from the classics to modern systems: Ruy Lopez, Sicilian Defense, Queen's Gambit, King's Indian, Caro-Kann, French Defense, London System, and hundreds more. Every opening includes all major variants with full theory coverage. ◆ RATED PUZZLES & YOUR REAL ELO Solve tactical puzzles that adapt to your level. Every attempt moves your puzzle Elo up or down, so after a handful of sessions you know exactly where your tactics stand — no guesswork, no self-assessment. ◆ GUESS THE EVAL See a position, drag the evaluation bar to your estimate, then compare with the engine's number and its best line. It trains the positional judgement engines have and most players never build — and it has its own Elo. ◆ DEEP VARIANT TRAINING Drill every branch of an opening, move by move. See your mastery rate per variant, identify the lines you keep forgetting, and focus your practice where it matters most. ◆ BUILD YOUR OWN REPERTOIRE Import any PGN file from your games or study materials. Or build an opening directly on the board — add new variants, edit existing lines, and create a fully custom repertoire tailored to your style. ◆ A DAILY HABIT Your session is sized for you and ready every day. Track your streak, earn XP, and unlock achievements as you progress. ◆ PROGRESS TRACKING Watch your mastery grow with detailed stats: success rate, mastered lines, rating trends, and your training week at a glance. ◆ AVAILABLE IN ENGLISH & FRENCH Start your first training session in under 60 seconds. ◆ SUBSCRIPTION Chess Virtuoso Pro is a weekly auto-renewing subscription.
