Your first analysis

Five minutes is enough to see what Régence can do. The goal of this page: take one of your games — ideally a loss whose turning point is still fuzzy — and get its explanation.

1. Open a game

Three paths lead to the board, take your pick:

• Drag a PGN file onto the welcome window — the drop zone lights up.
• File > Open a PGN file… (Cmd + O) to browse the disk.
• File > Open from a URL… (Cmd + Option + O) to paste the link of a Lichess or chess.com game.

No PGN file at hand? Both Lichess and chess.com offer a PGN export on every game — or better: connect your accounts to import your entire archives, but let’s keep that for later.

2. Start the analysis

The game opens on the board. At the top of the window, a blue button: Analyze. One click — or Analysis > Analyze the game (Cmd + Shift + A) — and the engine replays the game move by move, on your Mac.

Analyzing a game takes on the order of one to a few minutes depending on its length and your Mac. Progress shows live, and you can keep navigating the game while it runs.

3. The analysis is ready

A notification announces it: Analysis complete · N moves classified. The game has transformed:

• Every move in the list now carries a badge — green for good moves, orange for inaccuracies, red for mistakes and blunders.
• Both players’ accuracy shows as a percentage, with an overall verdict for the game.
• The evaluation graph draws the thread of the game — every swing is visible at a glance.

4. Jump to the decisive moment

Click the steepest point of the graph, or the move marked red in the list: the board jumps to the position. The arrow shows the move that should have been played, and the right panel shows the engine’s best lines. That’s where the loss explains itself.

That’s the essential. To learn how to read the analysis in detail — the ten move categories, the win percentage, the engine lines — head to the Reviewing a game chapter.
