These opening bids are based on and is a variation of the Precision bidding system and was developed by Mr. Ian Wilson of Irvine, California, United States. This information has not been confirmed independently from the source. The date of publications predates 1990.

Note: This Transfer Precision bidding system is not to be confused with the T-Precision (T for transfer) bidding system of Mr. Steve McGrahan.

Note: There are various versions of the Transfer Precision bidding concept. The attempt has been made to include as many as possible in time. If the information is not available on this site, then the request is made to send email and we shall attempt to find the information. Any information available from a reader, which is not found here, would also be greatly appreciated.

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.
