The forcing fourth suit
The forcing fourth suit
is used by the responder in the second round after the opener has bid two suits . This bid asks the opener for more information to find the best game contract.
Be careful! Dominique advises you to use the forcing fourth suit as a game-forcing bid until you are a first series player.
Like all artificial bids, the forcing fourth suit is only used when no natural bid is possible. For example, if a forcing support bid exists, you must use that.
