JoinCmd

Command to join an existing Reversi game from persistent storage.

Loads a saved game by name and optionally specifies which player you control:

• join gameName — Joins the named game

• join gameName # — Joins as Black (#)

• join gameName @ — Joins as White (@)

If a game is already in progress, it is automatically saved before loading the new game. If a piece type is specified, you will play as that color. If no piece type is provided, the system will assign an available color.
