In general, we use jumps in competitive auctions as weak bids (0-5 points) applying the Law of Total Tricks (LOTT) -- (though sometimes the modern approach can be to use mixed bids, 6-9 points). The key is that we jump to our Law level, eating up bidding space, to quickly and narrowly define our hand.
Fundamental Notrump Bids - 2NT Response by a Passed Hand: P - 1M - 2NT
When we are a passed hand and partner opens the bidding, we must be careful in trying to describe our hand. Partner’s opening bid in the 3rd seat can be light in values, trying to be destructive or lead-directing, so we cannot respond to it in the same way we would a normal opening bid. Specifically, if partner opens 1-Major in the 3rd seat, we should not go jumping around without a very special hand. Let’s look at how we should respond when partner opens in the 3rd seat.
Fundamental Notrump Bids - Upgrade to Jacoby 2NT
The modern expert 2NT response to a 1-Major opening shows a limit raise or better (LR+), instead of game forcing values. This has many different inventors, advocates, and variants. In Europe, it is known as Limit Sternberg while in America, Larry Cohen popularized a similar approach. The idea of using 1M – 2NT as LR+ accomplishes a couple of goals. First, this opens up 1M – 3M to always be a weak call (a valuable tool for making life difficult on the opponents). Second, 1M – 2NT as LR+ approach gives away less information about the Opener’s hand (and soon to be declarer’s hand). Let’s see how this works.
Fundamental Notrump Bids - 1-Minor - 3NT
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.
Fundamental Notrump Bids - 1-Major - 3NT
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?
Innovative Uses of Transfer Bids - Transfer McCabe

Innovative Uses of Transfer Bids - Transfer McCabe
The modern approach to improving our bidding structures (especially in competition) is to add transfers to our methods. This gives us more space and allows us to communicate more efficiently. When we play a system like McCabe, designed to give us more ways of raising partner and show support, we already have a useful structure. If we add transfers to this structure, we gain even more space for communication.

2/1 Game Forcing Variations - - 2 over 1 Game Forcing: 1D - 2C Auctions
The most complicated 2/1 GF auctions are the ones that start 1♦ – 2♣. Actually, these can be some of the most difficult auctions in all of bridge. These auctions can lead to lots of complexity and confusion about the meaning of bids on the second and third round of the bidding. Many pairs have played in 3-3 Major suit fits after the auction began with 1♦ - 2♣, thinking they were headed to a much better fit. Let’s look at what agreements we need to make with partner and then see how these affect our follow-up bidding.
2/1 Game Forcing Variations - - 2NT Rebid Showing a 6+card Suit
When we play the version of 2/1 GF that uses “2-Major Waiting” (meaning that Opener can rebid their suit without promising a 6th card), then we gain the ability to “right side” a NT contract when we have a balanced hand without a stopper in one of the suits. But, by having 2-Major be a waiting bid we make it harder for us to show our 6-card suit. Let’s see how we can add a gadget to help give us better rebid options to describe our hand.
2/1 Game Forcing Variations - - Opener’s Rebids After 2/1 GF Alternative Responses
When we choose to adopt the alternative approach to our 2/1 GF responses, 2♦ showing a 5+card suit, 2♣ being “could be short as 2 cards”, then this changes our reasonable options for rebids by the Opener. It is important that we have good agreements with partner about how this approach changes our rebid agreements. Let’s look at the hands that are simplified by these agreements and problems that are created.
2/1 Game Forcing Variations - - Alternative Approach
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).
Innovative Uses of Transfer Bids - Transfer Lebensohl Vs. Weak Jump Overcalls (WJO)
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.
Innovative Uses of Transfer Bids - 1-minor (Overcall) Transfers
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 developments in this area of bidding theory.
Innovative Uses of Transfer Bids - 1-minor (X) Transfers
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.
Innovative Uses of Transfer Bids - 1-Major (X) Transfers
When partner opens the bidding with a Major suit and right hand opponent makes a takeout double, the modern approach for many expert partnerships is to play transfer bids by Responder. When Responder transfers 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.
Innovative Uses of Transfer Bids - Transfer Advances Over Negative Double
When our LHO opens the bidding, partner makes a simple overcall, and Responder makes a negative double, then we are in the position of the Advancer. We can choose to play transfers in this position as well. By doing so, we give ourselves an additional step and we often allow ourselves more ways to raise partner. These transfer bids also cause some more difficulty for the opponents – making the meaning of their bids less clear. Let’s see how they work.
Innovative Uses of Transfer Bids - Transfers Over Transfers
Responding to 1NT is a balancing act of showing both strength and shape while keeping the auction at a low enough level. With a game forcing hand (10+ points), the goal is usually to be able to describe our hand below 3NT, particularly with hands that are strong enough to be interested in slam. This is not a problem with relatively balanced hands, but with distributional hands it may be more difficult for Responder to show their shape and explore slam without getting the auction too high (going past 3NT). Transfer bids allow Responder to show their shape while using space efficiently. After making a transfer bid, Responder usually gets to make a second bid without the auction getting much higher - one of the most valuable parts of playing transfers. A way to further improve our use of bidding space is to play transfer bids not only on the first round of the bidding, but on the second round also after a Major suit transfer. Let’s see how these Transfers Over Transfers work on Responder’s second bid after a Responder starts with a Jacoby Transfer.
Innovative Uses of Transfer Bids - Transfer Wolff Over 2NT Rebids
Transfers have become a larger and larger part of both competitive and constructive bidding. Transfers help with playing the contract from correct side, but they are also effective in searching for a fit while keeping the auction at a low level. One auction where transfers by Responder can be helpful is after Opener has started with a suit opening bid at the 1-level (1X) and then made a jump rebid of 2NT – showing a balanced hand with 18-19 points. Let’s see how transfers by Responder in this auction can help our side describe our hands in the limited space below 3NT. This treatment replaces Modified Wolff Signoff after a 2NT rebid.
Innovative Uses of Transfer Bids - Transfer Landy
There are two general categories of systems against the opponents 1NT opening bids – ones that use a Double as Penalty and others that use a Double as conventional. When the opponents open the bidding with a weak 1NT we need a good method for dealing with their unusual opening bid. The most common range for a weak NT is 12-14 points, but we define 1NT to be weak if the range does not contain 16 points. Some examples: 10-12, 11-13, 11-14, 12-14, 12-15, or 13-15 points. Against these opening bids we use a system that has a penalty double. Let’s look at one of the most interesting of these systems, Landy with Transfer bids.
Responder's Bidding Tools - Todd Busts Over 2♣ Opening Bids
When our side opens the bidding 2♣, we need an agreement about how we handle our responses. There are a variety of ways to handle this -- 2♦ waiting, Steps, Controls, 2♥ Bust. People have strong opinions about 2♥ for showing a bust. The players who dislike it are worried about “wrong siding” a ♥ contract. The players who like it like knowing that 2♦ is game forcing, determining if we are going to game or not immediately.
Responder's Bidding Tools - Responder’s Unusual 2-Major Jump Shifts and NT Bids
When partner opens the bidding 1-minor (1m), a jump shift to 2-Major (2M) by Responder can be used for a variety of different hand types. Both the standard approach of a strong jump shift and the common approach of a weak jump shift leave a lot to be desired. The modern style is for good hands to go slow, which makes a strong jump shift less appealing because it eats up valuable bidding space. With players responding to a 1m opening bid with 1M more and more aggressively, this makes using a weak jump shift less common even if it is our agreement. For these reasons many experienced partnerships choose to use these jumps to 2M for other constructive bidding purposes. Let’s look at uses of these jump shifts that can help us with some problem hands for Responder.
