The origin of this conventional method is unknown. The designation is also sometimes referred to as Swiss Fruit Machine. The guidelines and the requirements are the same as for the Swiss conventional response method. This means that the responder has opening values and a fit in the Major suit opening of his partner.

Principles of the Concept

Different from other variations of the Swiss conventional response method this variation offers several optional meanings as to the first response of 4 Clubs. In order for the opening partner to discover which option is intended this variations allows the relay bid by opener to discover exactly the meaning of the first response.

The bids and the significance of the bids are as follows:
