Summary of SWIFT: Standard WIth FanTunes Richard Granville, July 2013. This document may be freely copied and distributed. The world class pair Fulvio Fantoni and Claudio Nunes play a system called Fantunes, in which 2-level suit openings are natural and limited, while 1-level suit openings are unlimited, forcing and also essentially natural. The SWIFT system is derived from Fantunes and other sources, but is less complicated and more similar to Acol or SAYC. Table of opening bids: Opening Requirements 1♣ 13+ unbalanced, either 5+ clubs or 4441 with singleton diamond. Can also be 15-19 or 22-23 balanced. F1R. 1♦ 13+ unbalanced, either 5+ diamonds or 4441 with 4 diamonds. Can also be 24+ balanced. F1R. 1♥, 1♠ 5+ card suit, 13+ points. F1R. 1NT 12-14 balanced.

May be weaker if 3rd in hand, especially non-vulnerable. 2NT 20-21 balanced – may have a 5 card major. Other bids As in Acol. “13+” assumes 6 card suit or 5-4 (i.e. rule of 22, a queen more than Acol). Similarly, 2 of a suit is rule of 18-21.

Over a 1♠ opening, 1NT shows 0-10 points. After this opener may pass with a balanced minimum, or use 2♣ (Gazzilli). A 3♥ response to 1♠ is natural and invitational. Other responses are similar to the above. Gazzilli: responder makes cheapest bid with any 7+ points. Other rebids are essentially natural with 0-6 points. One could play a more natural scheme of responses to 1♥ and 1♠, along the lines of Acol or SAYC, but this makes it difficult to describe strong hands effectively. The combination of Two over One GF, Kaplan Interchange and Gazzilli works much better. .
