chessbook.net is a website that will allow you to relay any live chess tournament on the internet.
That does mean you are going to be using sensitive chessboards also known as DGT boards.
In order for chessbook to broadcast your tournament,
you will have to supply the link to the live pgn files.
You can also submit your chess clubs into chessbook's club directory, all that for free!
At this time, chessbook does not advertise upcoming tournaments
only submit your events if you are going to use chessbook to broadcast them!
