One feature of priority of these opening bids was to, by relay bids after a 1 Club opening, make the opener the declarer. The similarity between these opening bids and the Truscott Symmetric Opening Bids is obvious, but the subsequent bidding process, however, differs significantly as does the opening No Trump range.
