Anti-Lead Directing Doubles

Lead-directing doubles can be helpful in getting partner off to a good opening lead. These lead-directing doubles are common when the opponents make an artificial bid. But when the opponents make a cuebid of our suit, then a lead-directing double is also very common. Here we focus on this situation in detail in order to structure our agreements to allow us to communicate in the most effective way we can.

Scrambling 2NT

In competitive auctions where the opponents have found a fit, we will compete aggressively – especially at matchpoints. We will frequently use double (for takeout) with three-suited hands and sometimes with two-suited hands. To handle these situations, we want partner (Advancer) to have a tool to help us find our best fit. As usual, in competitive auctions our choice of convention will be 2NT. This gadget is called Scrambling 2NT.

Good/Bad 2NT

Good/Bad 2NT gives Opener two ways to compete to the 3-level – by bidding directly with a “Good Hand” or by bidding 2NT first with a “Bad Hand”. By using 2NT as a relay bid, instead of a natural call, this allows for a more precise description of Opener’s hand. Let’s see how it works through examples.

4NT in Competition

When the opponents stay out of our auctions then we usually have clear agreements about the meaning of a 4NT bid – usually Quantitative in a NT auction and Keycard in a suit auction. But in a competitive auction we are more likely to use 4NT as a bid showing 2 places to play. Let’s look at some of these auctions so we know what partner is trying to do to when they use 4NT in a competitive auction.

Non-Leaping Michaels

When the opponents open the bidding with a 3-level preempt then much of the tension in our decision-making process comes around “Should we bid beyond 3NT?” This is especially true when the opponents open the bidding with a 3-Major preempt. Because when we have one long minor suit then we likely want to play in 3NT or 5-minor. This allows us to use 4-minor in some interesting conventional ways, just as we do vs. a 2-level preempt.

DEALING WITH 4-LEVEL PREEMPTS

When the opponents open at the 4-level they put a lot of pressure on us to make difficult decisions without much room to maneuver or describe our hand. This preempt will force us to either double or overcall at a very high level – we will not have many of the options that are available to us at lower levels. Let’s look at each of these options and see how we need to adjust our thinking and bidding because of the lack of space and options available to us.

LEAPING MICHAELS

When RHO opens a 2-level preempt, they have started eating up our valuable bidding space. But this is just the start of their attack on us. LHO may join in the attack and raise the preempt, making our life even more difficult. When we are bidding over RHO’s 2-level preempt we should keep this in mind. We need lots of tools to deal with this situation. Let’s look at these options.

SLAM TRIES AFTER STAYMAN

One of the most common gadgets that we use when partner opens 1NT is Stayman. We primarily use Stayman to search for a 4-4 Major suit fit. After Stayman sometimes we want to have a way to raise partner’s suit where they cannot pass. We will want a “Forcing Raise” (similar to Jacoby 2NT or Inverted Minors) in order to find out more about Opener’s hand. This is missing from a standard bidding system. It is a valuable tool for making a slam try while keeping the auction from getting too high.

TRANSFER AND MODERN LEBENSOHL

Lebensohl is an excellent system for dealing with interference over our 1NT opening bids. But Lebensohl has some flaws. In Lebensohl auctions we will often play the hand from the “wrong” side (Responder’s side.) Another flaw in Lebensohl relates to Responder’s strength. Responder often has three strengths (buckets) let’s see how Transfer Lebensohl is an upgrade to this.

DONT RUNOUTS

When we open the bidding with 1NT, showing 15-17 points, if an opponent makes a penalty double, we are less likely to be looking to invite or bid game. We are usually looking to escape from a 1NT contract and attempt to find some safer place to play. This safe place will hopefully be our largest fit or a long suit in the weak hand (in Responder’s hand). In order to find this place to play we need to look at how Responder’s bidding options change after a penalty double.

DEALING WITH 3-LEVEL INTERFERENCE

There are many systems the opponents play in order to interfere over our 1NT opening bid, but almost all of these systems use the 3-level (actually 2NT+) for the same meanings – 2NT as a weak bid showing both minors and 3-level bids as weak with a long suit, preemptive. It is important that you and partner are on the same page for how to deal with this higher-level interference.

LEBENSOHL

After partner opens 1NT, we have a good structure for using our bids efficiently to describe our hand to partner. But when the opponents interfere in our auction, we lose some of this valuable bidding space and need to change our approach in order to deal with their interference.

LANDY & TRANSFERS+

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. When constructing a system to allow us to bid over these weak 1NT openings we need to take a different approach than bidding over a strong 1NT opening. We frequently may have a powerful enough hand to be interested in exploring game when the opponents open a weak 1NT. Thus, we construct our bidding system to allow us to explore game and make constructive bids, not just be destructive.

PENALTY DOUBLE SYSTEMS

When the opponents are playing a “Weak 1NT” opening bid (for example, 12-14 points), we need to bid only when we have a decently valued hand. We tend to bid with hands that would normally have overcalled at the 2-level, hands with about opening values. Here we are primarily bidding constructively because when the opponents open a “Weak 1NT” our side may still have game. If we bid destructively (with only shape and without much strength) then if partner has values, they may push the auction too high. It is common to use a different bidding system against the opponents’ Weak 1NT opening bid than the one you use against a strong 1NT opening. These systems usually contain a penalty double that allows us to show a very good hand as well, and thus penalize the opponents when partner also has some values.

WOOLSEY

There are many artificial systems for competing over the opponent’s 1NT opening bid. Woolsey is focused on finding Major suit fits while allowing us to compete as cheaply as possible.

DONT & MECKWELL

When the opponents open the bidding with a strong 1NT the hand usually belongs to them, as we are less likely to have a majority of the HCP. We usually compete with shapely hands - 1-suited or 2-suited distributional hands. With these hands we turn our focus to getting in the opponents’ way and further competing in the bidding when our side discovers a large fit. Many modern bidding systems (the kind that use artificial structures) over the opponent’s 1NT opening bid are designed with this competitive bidding approach of destructive bidding with distributional hands in mind.

Last Train

One of the ways that we investigate slam in a suit contract is the use of control showing bids. When one member of the partnership is interested in slam then they show this interest by making a control showing bid. But as the auction approaches game we have a big decision to make, should we go past game or not. This can be a difficult decision; we should not go past game without a good reason -- some extra values. In this situation we would like to have a way to make “one more try for slam”. The way that we do that is with a convention called the Last Train to Clarksville (“Last Train”).

Non-Serious 3NT/3S

When we find a Major suit fit at the 3-level in a game forcing auction, then partner is usually expressing interest in slam (because without slam interest, partner would have applied the Principle of Fast Arrival and bid 4M.) In this case, now we usually express whether we have slam interest or not by either making a cuebid or simply bidding game with 4M. A partnership can use a gadget called “Non-Serious 3NT” to gain even further clarification about a player’s level of slam interest.

Q-Minorwood

When we have a minor suit fit, using 4-minor as Keycard in our suit (Minorwood) is an effective tool for exploring slam without getting the auction beyond game, beyond 5-minor. But by adopting Minorwood, we give up the natural slam try of 4-minor, asking partner to do something forward going for slam, usually starting to make a control showing bid, if they like their hand. By making an improvement to our Ace-showing structure in Minorwood, we can combine both Keycard-asking and quantitative bidding into one structure. This new structure is called Q-Minorwood. Let’s see how it works.

Responding to Keycard with a Void

When partner bids 4NT as Keycard in our established fit, a void in a side suit can be useful. We may still be able to make a slam if we are missing two Aces/Keycards if the void is in a suit of one of those missing side Aces. We need a way to tell partner about this void if we haven’t already done so earlier in the auction.
