At the start of our game interface, the chessboard is blank and the game does not start automatically. So if you want to move the pieces, they remain frozen.
To find an opponent, you must either send a proposal to play to a player or accept one from a player. In the game interface, the proposals to play are commonly called “challenges”.
You can send/accept proposals of play in the area at the left of the chessboard or ask the server to automatically find an opponent corresponding to the defined game settings.
