All features

Ten areas, one trainer. Pick a feature below to see how it works.

The trainer

Learn the idea, then play it without help

Four modes that build on each other: browse the line, learn why each move is played, practise it with nothing in front of you, then prove it against the clock.

→

Opening library

100+ opening courses, organised the way openings are

Every official course grouped by family - Sicilian, semi-open, queen's pawn, Indian defences and more - each one trainable as White or as Black.

→

Repertoire builder

Build a repertoire that fits your games

Pick the lines you want to play with White and the defences you meet as Black, then train the whole thing as one connected repertoire.

→

Endgames Vault

Checkmate drills that actually stick

The same trainer, now for the basic mates and the classic rook endings. Learn the technique, then convert it without help.

→

Game Review

See the whole game at once, without the engine noise

Upload your game and the trainer shows, move by move, where the position crossed into unfamiliar territory - the exact spots your opening preparation ended.

→

Blunder Override

Find the mistakes hiding in your opening prep

A focused pass over your recent games that finds the positions where you left your prepared opening lines behind - the blunders that a little extra drilling would have prevented.

→

Evaluation

Practice data that points at your next study session

A dashboard across your openings, endgames, and puzzles that answers one question: what needs another round of practice this week.

→

Puzzles

99,000+ puzzles matched to your rating

Tactics puzzles that stay in the rating band you are actually playing at, with enough thematic variety that you do not memorise the shape of the solution.

→

AI Coach

Train with a coach that explains every move

Play against the Cyber Chameleon and get live coaching notes as you go — why a move worked, what you missed, and what to try next.

→

Sparring

Training games against styled opponents

Face the jungle ladder — five partners from about 800 to 1800 Elo — and sharpen instincts without spending coach credits.

→
