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
When partner opens the bidding with 1§ or 1¨ then our primary objective is to look for a Major suit fit. We do so by responding to 1-Major when we have a 4-card Major suit. We do so if we have 6 HCP or even enough for game (a good 12+ points). If we do not have a 4-card Major suit, but we have a balanced hand with enough values for game, then our most common action is to just bid the game we are likely to make, 3NT! Let’s look at this 3NT response in more detail and see what is going on with this response.
Bidding
When partner opens 1-Major and we play 2/1 GF, then a 1NT response is used with most hands that have minimum or invitational values without a fit, showing 6-11 points. A 2NT response to a Major suit opening is not used as a natural bid because it is Jacoby 2NT, showing game forcing values and at least 4-card support. So the question is what should a jump to 3NT in response to a 1-Major opening show?
Trick Taking
One of the ways that we develop additional tricks (beyond Quick Tricks) as declarer is by using our long suits – Length Tricks. These tricks usually depend upon good luck or “suits splitting well.” This can sometimes be done immediately (without giving up the lead) or sometimes requires some work to develop these tricks. As a defender, when we are on lead (especially opening lead against a NT contract) we use a similar technique for developing tricks from our long suits. Let’s see how we use our long suits to develop tricks as a defender.
Trick Taking
We develop a lot of techniques and skills for taking tricks as Declarer. In this case, we can see the dummy and our hand (and thus all of our sides assets). Many of these techniques have parallels for how we take tricks on Defense. These skills are used in the middle of the hand (when we can see our hand and the dummy) and they are used on Open lead, even when we cannot see anything other than our hand. Let’s take a look at some techniques we first learn as a Declarer and see how we use them on Defense.
2/1 Game Forcing
When we agree to play 2/1 GF as our bidding system, then that is not the end of our decision-making process. We need to discuss our follow-up bidding and other initial agreements. The goal is this article is to give you a list of questions to discuss with your partners, to make sure that you are getting the most out of your 2/1 GF system. Let’s start out with a list of the question and then we’ll do some discussions of options below.
