Innovative Uses of Transfer Bids - Transfer Lebensohl Vs. Weak Jump Overcalls (WJO)
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
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
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
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
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
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
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
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
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
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.

Responder's Bidding Tools - Inverted Structure
Responder's Bidding Tools - Inverted Structure

When we use Inverted Minors to raise partner’s suit, the traditional approach is to show Major suit stoppers and determine whether we can play a notrump contract.  A more sophisticated approach is to use an artificial structure that allows Opener to show their hand type and strength and allow Responder to determine where to play the final contract (and who should be the declarer in notrump).  A similar approach to this structure can be used in 1♦ – 2♣ auctions as well.  Let’s look at some of these methods in detail.

Responder's Bidding Tools - Reverse Flannery
Responder's Bidding Tools - Reverse Flannery

Another approach for using 2♥ and 2♠ responses to 1-minor suit opening bids is to use these bids to show a variety of problematic hands that have length in both Major suits.  This method, called Reverse Flannery, is particularly effective after a 1♦ opening bid.  It originally comes from Precision where 1♦ is the only “natural” 1-minor opening bid.  Let’s look at how this works and see what types of hands these agreements can help us bid better.

Responder's Bidding Tools - Responder’s Systems After a 1NT Overcall

When partner opens the bidding in a suit at the 1-level and the next player overcalls 1NT, we want to have a system that allows us to deal with this interference effectively.  With a good hand (which is somewhat rare in this auction), we make a penalty double.  With a poor hand that is relatively balanced, we likely want to stay out of the auction and simply pass.  It is the distributional hands with some values, but less than 10 HCP, where we are likely to want to compete in the bidding.  One way to make it easier to bid with these distributional hands is to use a system similar to what we do when the opponents open 1NT.  Let’s look at what systems we should use in these auctions and how our system varies based on which suit partner opened.

Responder's Bidding Tools - Kokish Game Tries

When we find a Major suit fit and we are interested in game (specifically in the auction 1M – 2M), we want to have a good way to explore or invite game.  The traditional way to do this is to ask for help in a side suit, using a Help Suit Game Try, HSGT.  We additionally have 2NT available to make a general try for game (some play it as trump suit GT) and a raise to 3-Major to mean 1-2-3 Stop (or generally quantitative/general GT.)  This structure is reasonably effective in exploring game.

When the auction begins 1X – 1Y – 1NT (where X and Y are different suit bids), the modern treatment is to play Two-Way New Minor Forcing.  This approach uses both 2♣* and 2♦* as artificial and forcing bids by Responder.  2♦* is an artificial game forcing bid, while 2♣* is generally used to start invitational bidding sequences. XYZ is a convention that is an extension of this approach in other auctions that start with three bids at the 1-level.  Let’s look at the details of how this can improve our bidding.

Responder's Bidding Tools

New Minor Forcing is an excellent convention for continuing the auction when Opener has shown a balanced hand that is weaker than opening 1NT. But after a New Minor Forcing bid, the auction often gets complicated if we don’t go straight to game.  It can be confusing whether we are inviting game or trying to make a slam try – which bids are forcing and which bids are non-forcing?  2-Way New Minor Forcing is an upgrade to New Minor Forcing that allows Responder to better describe their hand and simplify and clarify the rest of the auction. 

Responder's Bidding Tools - Modified Reverse Two-Way Drury
Responder's Bidding Tools - Modified Reverse Two-Way Drury

The concept of having a conventional bid like Drury available to show a limit raise in support of partner’s Major suit when we are a passed hand is a regular part of most partnerships’ passed hand bidding structure.  Given that making a 2/1 bid into a minor suit is not that attractive (or even possible!) by a passed hand, it makes sense to allocate both 2♣ and 2♦ as artificial raises of Opener’s third seat (or fourth seat) Major suit opening bid.  Many partnerships that play Drury play 2-Way Drury, using one bid to show a 3-card limit raise and the other a 4-card limit raise.  But a more sophisticated structure can allow us to describe even more hand types in the same bidding space.

Exclusion Keycard

When we are interested in slam in a suit contract but have a void in one of the side suits, it adds some complexity to our slam bidding.  We may be able to make a slam missing two Aces (or a grand slam missing an Ace), if partner does not have the Ace opposite our void.  When exploring slam, we want to know if partner has that Ace or has the “good Aces”, the ones opposite our losers.  One way that we find out about the location of partner’s Aces is by using control showing bids. This is especially effective if we use them to show first round control (if we play that our control showing bids could be 1st or 2nd round, then we know less about which Aces partner hold).  There is a gadget that we can use in some auctions that allows us to try to solve this problem.  This convention, called Exclusion Keycard, asks partner for their number of Keycards (or Aces if we play Blackwood), excluding one particular Ace – the place where we are void. This Exclusion allows us to find out if partner has enough of the “right Aces” for us to make slam.

Kickback Keycard Ask

Kickback is a convention that can make slam bidding easier, in that it gives us more space to ask partner for the Queen of trump, but it can also cause problems for us in the bidding.  Any time we make a game contract (like 4♥ or 4♠) a conventional bid, there is danger that we have an expensive mixup with partner.  Here we look at some classic danger auctions that may come up if we choose to play Kickback and then discuss some of the common partnership agreements or philosophies for how to handle these dangerous auctions.

Kickback Keycard Ask

One of our most commonly used tools for determining if we should bid slam or not is Keycard Blackwood. The most popular version of this is 1430 Keycard. This tool allows us to exchange a lot of useful information with partner.  We attempt to determine how many of the 5 Keycards we have, plus we also hope to be able to determine if we have the Queen of the trump suit. When ♠ is the trump suit, then we have plenty of bidding space to communicate, but when lower-ranking suits are the trump suit, using 4NT to ask for Keycards leaves us little room to exchange information without getting the auction too high.  To fix this problem, some partnerships use Minorwood for their minor suit Keycard auctions, but this does not solve our problem in the ♥ suit. There is another approach, called Kickback, that tries to solve this problem. Let’s see how this works.

Keycard Blackwood Details – More Specific Kings

In an Ace-asking auction, when we make the follow-up bid to ask partner about their Kings, we usually do so to investigate a grand slam (though some partnerships do this in order to determine if 6NT is good contract). Most partnerships start with the agreement that they answer this question by showing their number of Kings. But sometimes, a Grand Slam is not about partner having 2 or 3 Kings, but about them having the right single King. This “right King” is often the one opposite our long suit – allowing us to produce a large number of tricks. To get this information, many partnerships evolved their Kingshowing methods from “number of Kings” to “Specific Kings.” Here we look at how we can use Specific Kings in a variety of our Ace-asking auctions.

Keycard Blackwood Details – More Queen Asks

Jacoby 2NT is a useful convention, but many players choose to try to improve it.  The modern expert 2NT response to a 1M opening showing a limit raise or better (LR+), instead of game forcing, has many different inventors and advocates.  The idea of using 1M – 2NT as LR+ accomplishes a couple of goals: 1) It opens up 1M – 3M to always be a weak call (a valuable tool for making life difficult on the opponents). 2) 1M – 2NT as LR+ approach gives away less information about the Opener’s (soon to be declarer’s) hand than Jacoby 2NT. Let’s see how this works and how it can help improve our bidding.  This one is fun for system bidding fans!

Preempt Blackwood

When partner opens the bidding with a 2-level or 3-level preemptive opening bid then Responder may have a struggle to find the best final contract without getting the auction too high.  One of the natural pressures is whether Responder risk going past 3NT to look for a fit or a better fit.   If Responder has an extremely strong hand then they may be interested in exploring slam in preemptor’s suit, but again Responder may face a concern about getting the auction too high.  If Responder uses 4NT as Keycard Blackwood to explore slam, then the partnership may get too high and go down.  Given the variability of modern preempts it can be dangerous to reach the 5-level when partner has taken an aggressive action.  Here we look at a tool, called Preempt Keycard, for Responder to ask for Keycards after a preempt, but still keep the auction at a low level.

Jump-Shift System

Balanced hand bidding is relatively easy. We can usually describe our hand to partner by opening 1NT or rebidding 1NT. This lets partner know both our points and our hand type with either our first bid (when we open 1NT, the best situation) or with our second bid (when we rebid 1NT).  However, if we have a big balanced hand then we need to have tools for describing our hand as well.  These usually involve the use of 2NT – as a rebid, an opening bid, or even a rebid after having opened the bidding 2♣.  But this does not solve all our bidding problems when we have these large balanced hands.  Let’s look at these auctions in detail, see some of the issues, and then look at a useful gadget called Kokish to help us bid better.

Freebids by a Passed Hand

When partner makes a bid, and we choose to bid a suit of our own, this is called a freebid. In most normal situations freebids show values (called positive freebids) and are often forcing 1-round. We’ve all heard the saying -- a new suit is forcing by an unpassed hand.  Unfortunately, this is not always true, but it is often our agreement. Let’s look at freebids made by a passed hand and see how the fact that we are passed changes these situations.

Fit -Showing Jumps

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.

Bergen Raises

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.
