After the board appears, you can choose to practice or to start a game with somebody on the Net. In the Practice mode you can see what the various boards and pieces look like, and you can play the pieces of both sides. QuantumChess validates all input and will not allow you to make an illegal move. A dialog box will then be displayed, showing a list of all the people playing or waiting to play a game. You can choose a waiting person from the list by clicking on the desired entry.
People waiting have a green icon, while people who are playing have a red icon.
The list is updated automatically every 30 seconds. Once you have chosen an opponent, the IssueInvitation button will become active and you can then press it. Your invitaion will be sent to the indicated person, who may accept or reject it. If there is nobody waiting, or nobody waiting who you want to play with, you can press the WaitForInvitation button. A dialog appears which will show you information about anybody issuing an invitaion to you.
