Warning, this system is rather complicated, contains a lot of unusual elements, thus it is not recommended for beginners or occasional players! If you do not play at least twice a week then you will probably do better with a simpler system.
The system is based on precision club, but similarities almost end here. Bidding with gameforcing hands follows the relay principle, i.e. investigating of one of the players' hand. Other bids differ from their classical precision meanings too, because almost all gameforcing hands start with a relay.
