When the opponents open a Weak 1NT, we should adjust our bidding system to accommodate it.
2/1 Game Forcing
There is not just one version of a 2/1 Game Forcing bidding system. There are a variety of conventional rebids that are additions to a fundamental 2/1 GF system, but there are also some fundamental response agreements that can be adjusted. One of these is the length that we promise when we respond in a minor suit at the 2-level. In the standard 2/1 system a 2♥ response shows at least a 5-card suit, a 2♦ response shows at least a 4-card suit, and 2♣ usually shows a 4+ card suit (occasionally it could be a 3-card suit). Let’s look at these responses in detail as well as an alternative response structure where we require 5 cards to bid 2♦ and then must use a 2♣ response with a large variety of hands.
Competitive Bidding
Transfers are an extremely useful tool for competitive bidding. So are relay bids, like the way we use 2NT in a Lebensohl auction. We can play a useful system, like Transfer Lebensohl, in a variety of different situations. Let’s see how we can use these methods after partner opens the bidding and the opponents take away our bidding space with a Weak Jump Overcall.
Competitive: General
When partner open the bidding with 1-minor and our RHO makes an overcall of a suit, then we need a way to describe our hand to partner. The traditional Responder tools are negative double and positive freebids, but in some auctions, there are other approaches that use transfers to give us a better way to compete as Responder. Unfortunately, we don’t have a transfer structure in every auction (when they overcall 1♠, we have very few good systems) but hopefully there will be more and more interesting development in this area of bidding theory.
Adv Comp Bidding
When partner opens the bidding with a minor suit and right hand opponent makes a takeout double, the modern approach for many expert partnerships is to play transfer bids by the Responder. By Responder transferring to the suit with length instead of bidding it, we gain many advantages in these competitive bidding auctions. Let’s look at how we use these transfers by Responder and what they gain for us.
