Opening Bid: One Club - 17+ HCP
An opening bid of 1 is the cornerstone of any strong club system. Although the Precision system defines a strong hand as one with 16 or more points, our club system requires at least 17 points. 17 points is the dividing line between normal opening hands and strong, forcing hands. It's not an important distinction, but the methods described here will use 17 HCP as the criteria. Because of this, we do not use the standard 15-17 point range for an opening bid of 1NT, nor do we use the popular 14-16 point range used by most Big Club systems. Our 1NT opening is 15-16.
Negative Response Bids
The first thing to learn is the negative response after a strong 1 call...
Positive Responses and Asking Bids
Other than the 1 bid and the 5-8 point jump bids, all other bids show a minimum of 8 points and are forcing to game.
Repeat: Any response to 1 except 1 (and jump responses) is forcing to game, and shows at least 8 HCP.
Responder bids 1NT with 8 or more points and no 5-card major
Trump Asking Bid - TAB
When responder names a suit, showing at least five, the opener can raise the suit as an agreement on trump. The raise is also a Trump Asking Bid and requires responder to use step rebids to describe the quality of her suit.
Support Asking Bid - SAB
When responder bids either a suit or notrump, the opener can then bid a new suit, which is at least a 5-card suit, and is also request for responder to uses steps to show how well she can support the suit. Responder's replies can show poor support, moderate support or good support, as well as control-showing.
Control Asking Bid - CAB
After a positive response by the responder, either a suit or a notrump call, opener can ask about the number of controls held by responder. Opener asks by bidding notrump. 1NT over responder's 1-level bids, or 2NT over responder's minor suit calls. (An ace is two controls, and a king is one.)
A Rebid of 1NT by Opener Shows 18-20 Points
Responder can use the standard bids of Stayman and Transfers.
Transfer Over Stayman - TOS
If Responder bids 1NT with 8+ points, it shows a balanced hand and at least 8 points. Unlike many older Precision systems, this bid is not limited in point-count.
Opener might rebid a suit, promising at least a 5-card suit, and is SAB, the Support Asking Bid. But the opener can also bid two clubs, which is Stayman. Because there are advantages to having the strong hand be the declarer, responder does not bid a 4-card major directly, but instead uses Transfer responses.
Opener might prefer to simply rebid 2NT, instead of using Stayman. Treat this as CAB... the Control Asking Bid.
If an opponent doubles or overcalls, we can use either a pass, a double or a redouble to convey information. We can also simply bid a new suit to show at least 8 points and a positive response, and a cue bid is available.
Okay, this is a little bit complicated, but it is very precise and it's fun.
