One of my favorite sayings is “2NT is a convention, not a contract.” In specific situations, Responder can use 2NT as conventional raise of Opener’s suit. Sometimes we need to choose between several different conventional methods for competitive auctions. Here we look at our options for how to best use 2NT.
When responding to partner’s 1-Major opening bid, Responder tries to apply the Law of Total Tricks (LOTT) – getting to the size of the partnership’s fit as quickly as possible. This is particularly true in competitive auctions but is also useful in constructive auctions. Responder must balance showing the size of their fit with showing their values. This LOTT bidding is especially effective when our side has a 9+card fit. In this case, the auction is likely to become competitive if the opponents have some values as well. Predicting this to happen, we would like to be able to compete to the 3-level with a 9+card fit as quickly as possible, eating up the opponents’ bidding space while showing our values. Bergen Raises are a set of conventional bids Responder can use when responding to a 1-Major opening bid with 4+card support (at least a 9+card fit). Let’s see how this system works.
When the auction begins 1m – 1NT (both bids by the opponents), it is rare that we want to compete in a minor suit. Usually in these auctions the opponents have the minors, since Responder has denied a 4-card Major. (Even if we have a 5+card minor suit, it could still be best to pass and defend 1NT.) In these auctions, it is effective to play a system geared towards the Major suits where we are most likely to have a fit. Spear is an artificial system that uses all the bids at the 2-level to show different Major suit hands. This gives us more options for how to compete in the bidding. Let’s see how it works.
The modern game continues to create interesting auctions and we need to make sure to discuss how to respond to new situations with partner. Some of the most interesting (and useful) competitive bids are when we use a suit that the opponents have bid – called a Cuebid. Let’s take a look at cuebids of the opponent’s suit in a variety of different auctions and make sure we are on the same page with partner about the meaning of these calls.
When Left Hand Opponent (LHO) opens the bidding, partner makes an overcall, and Right Hand Opponent (RHO) makes a negative double, then Advancer is in the middle of a complex competitive auction. Traditionally, a redouble in a competitive auction shows a strong hand (10+ points), but with everyone bidding it is not likely that Advancer is too focused on showing values. Instead, we want to design our agreements to let us best describe the most common kinds of hands. In this auction, Advancer having lots of values is not common. Let’s see how using redouble as a conventional bid, called a Rosenkrantz Redouble, can be more effective than this traditional value-showing redouble.
