The opening explorer

For every position, the explorer answers one simple question: what gets played here, and how does it go? It shows via View > Opening explorer (Cmd + Option + E), below the analysis panel.

Three sources

The selector at the top of the panel picks the population of games consulted:

SourceWhat it shows
LibraryYour own games that went through this position — how many, and the moves you played there
Lichess — mastersThe master games database: theory in practice
Lichess — all playersMillions of amateur games: what actually gets played at your level

For each move played from the position: the number of games and the win / draw / loss split, as a colored bar. Clicking a move plays it on the board — you can walk down a whole opening this way.

The use that builds progress

The masters and amateur databases tell two different stories — and that’s the whole point. A move can be theoretically correct (masters play it) yet treacherous in practice (amateurs collapse in it), or the reverse: a theoretically dubious line that scores heavily at 1500 because the refutation is hard to find.

The Library source turns the explorer into a mirror: on a recurring opening position, it shows at a glance your past choices and their results. If a move shows 2 wins for 8 losses there, the statistics section will have nothing to add — the conclusion draws itself.
