Review flow

Start with one game

These pages all lead back to the same place: import a game, review it, and use what the review found.

Step 1

Paste or upload

Bring in a single PGN or a multi-game PGN file. ChessIQ validates before opening analysis.

Step 2

Open Analyze

The workspace shows move labels, evaluation swings, accuracy, and best-line context.

Step 3

Save useful positions

Stable missed chances and blunders can become Training positions automatically.

Step 4

Return later

Reviewed games reopen from Archive and contribute to Statistics on this device.

Proof

Built for product-aligned PGN intent

It goes straight to review

The PGN page is not a content detour. The main action opens the same app workflow as every other intake.

Multi-game PGNs are expected

If a file contains multiple games, ChessIQ routes into selection instead of silently guessing.

Move labels have context

Labels are paired with evaluation changes and best-line alternatives so the review is inspectable.

Training is connected

The follow-up is not random tactics. Training positions come from the reviewed PGN when validation supports them.

Quick answers

Can I paste a Chess.com or Lichess export?

Yes. Standard PGN exports with headers are supported.

Can I upload a file?

Yes. `.pgn` and plain-text PGN files can be loaded from the PGN input.

Does ChessIQ analyze every move?

The analysis workspace evaluates the game move by move and can continue deeper while the board remains open.

Why might no training be created?

ChessIQ only saves positions that pass its training validation. A completed review can honestly produce zero saved positions.
