Help about B net...

[H4Sh4D]

If i have a friend on B net i want to challenge for a game.. .How do i de that most easily? is that though a custom game or is it something smarter?

You should indeed create a custom game. Create a private game and tell your friend its name so he/she can join the game (this is to prevent unexpecting players to join your game by accident).
If you'd like to play with your friend as a team against other random players, you can use the arranged team option.
