These opening bids are based on the Precision Club, feature the opening of a 5-card Major suit, and employ a reduced value for a No Trump opening. The 1 No Trump Forcing convention after an opening of a Major suit is employed. Opening 3 Clubs promises a strong, semi-solid and strong Club suit, whereas a 3 Diamond opening promises an unknown solid suit with no side values.

The original Precision Club bidding system consists of a strong club system that was invented by Mr. Chung Ching Wei. This bidding approach was employed by him and team mates from Taiwan in the early 1970s. The success of this approach gained adherents and many bridge players of different nationalities began experimenting with the basic concept. Today the most common feature of all bidding systems based on the concept of Precision, as originally conceived, is the feature of a strong Club opening.

This variation on the opening bids was developed in Sweden and the originator is unknown.
