Opener, overcaller, responder, advancer.
When learning a convention, it’s important to recognize which position uses the convention: the opening bidder, the overcaller (first person to bid for the non-opening side), the responder (partner of the opener) or the advancer (partner of the overcaller). Some conventions are only played by one of the positions and some can be played by any position. Do you know which is which?
