How to use the PGN viewer

Paste one complete game

PGN tags are optional, but standard algebraic move notation is required. Comments and variations may remain in the file.

Replay the critical moment

Use the move list or arrow controls to compare the notation with the position after each move.

Follow the opening match

An Opening tag takes priority. Without one, the viewer compares the main line with trainable lines in the Chessmate catalog.
