Chapter 4. Markers

Markers are highlights of squares on the chessboard. They can be used to show legal moves for your chess piece, the opponent's previous move, or a king in check. Their color and shape depends on which theme you are using. They can be toggled on/off in the general settings section of the configuration menu.

Clicking on your piece during your turn displays a marker on every square on which that piece can be moved. The picture shows the legal moves for the white queen.

When your opponent has made a move, their last move is indicated by markers. One marker shows the initial position of the chess piece, and a second highlights the new position of the chess piece.

If the opponent's last move put your king under attack (“check”), your king and all attacking pieces are highlighted as well.
