Analysis Workspace
Explore moves · evaluate with Stockfish · cross-reference games · save lines.
You don't have to reinvent chess theory here — you build on it. Whether you're learning your first opening, preparing a tournament repertoire, answering an unusual move you keep facing, or sharpening a repertoire you already trust, the same five steps apply.
- 1. Explore
Start from established theory. The Explorer and the database show what players actually play from here.
- 2. Analyze
Drag pieces on the board. Stockfish evaluates every position live while the database shows real game trends.
- 3. Build
Pick the responses you want to play — not the ones a course picked for you. Any legal move can become your line.
- 4. Save
Save the sequence to an opening book. Books are grouped by colour and merged into your theory tree.
- 5. Train
Drill your own saved lines with spaced repetition, or rehearse a full line move by move.
