Here we look at a modern expert treatment in 2/1 GF auctions which uses a 2NT rebid like the rebid of a suit — showing a 6+card suit. Let’s see how it work and how it helps redefine our bidding structure.
Bidding, Competitive Bidding
When we are in a game forcing auction and the opponents interfere (usually to sacrifice) it is clear that we are not going to go quietly and just let them steal the contract. If the opponents bid over us, then we will either double them and defend or bid on to our game. Forcing Pass is an agreement used to help us work together with partner to make a good decision about which to do.
Bidding, Constructive: Responder, Constructive: Opener
When partner preempts the bidding at the 2-Level, and we have a good hand we expect the auction to be difficult. We need to have good agreements with partner and exercise some good judgment to get to the right final contract. When we have a fit for partner’s suit (especially a Major suit) then we know what strain we are likely to play in. We need to exchange useful information with partner. There are a variety of systems for accomplishing this, including Optional Feature, Ogust, Steps, and Modified Ogust.
Bidding, Constructive: Responder
When partner opens the bidding with 1-Major and Responder makes a Splinter bid then this shows our fit, values, and shortness all in one call. This gives an excellent description of our hand and allows partner to re-evaluate their hand based on their working values. In a sophisticated partnership we may choose to have multiple types of splinters, allowing us to communicate even more information to partner. Here we look at the use of Over-Splinters and see how we can use them to give partner additional information about our hand, allowing them to better judge if slam is likely to be a good contract.
Bidding, Constructive: Responder
Here we look at when to raise responder's suit on 3-card support. And then what we do after that -- the trump asking bid, sometimes called Spiral.
