These opening bids are based on the Carrot Club bidding system as formulated by Mr. Anders Morathand and the basic concept of the Precision bidding system as formulated by Mr. Chung Ching Wei. This version employs a variable Weak-and-Strong 1 Club opening system. The 1 Diamond opening promises a limited range and undisclosed distribution.

The origin is unknown, but the basis of the system is the application of opening a 5-card Major suit. Any first response after a variable Weak-and-Strong 1 Club opening are considered natural, but subsequent rebids, however, are relay bids.

Note: Any additional information as to the origin of these opening bids were be greatly appreciated.
