  5. Connect to each other within a minute.
  6. Click on the "+" Symbol at your friend to show the connection with the pipeline symbol: *Right* Mouseclick to see the context menu (shown for online friends).

PS: Some further "tips":

  • You find your own Messenger ID in the button under the friendslist (Add Friend & Send my own Messenger-ID).
  • The "People" Tab allows to add more friends with right mouseclick, so the whole chess club could online with you soon... Today dont look on a wooden chess plate, both look to each other with a laptop in front and play chess over InterFace - InterFace allows to leave the chess club for home and continue to play in the evenings or at any time..
  • Forwarding a Port in the Firewall/Router helps to connect faster, if not forwarded, it might take a minute ot two for the initial handshake connection.
  • To Play Chess: Be sure to right click not on the friend, but on the connection pipeline under your friends name to use this connection (your friend can have several connections, e.g. one to his mobile laptop and the other to his chess desktop at home - so decide with which device you want to start a game).
