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.
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.
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.
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.

When the opponents open at the 3-level or 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.
When we overcall vs. a 3-level or 4-level preempt we face more danger than when the opponents open at the 1-level.
First, we are at a higher level, and
Second, the opponent behind us might have a good hand and be armed with a penalty double (as opposed to a negative double if our RHO had opened at the 1-level.)
Thus, when we make an overcall at a higher level we want to have a good hand and a good suit.
If we have both a good suit and a good hand, we should be able to “survive” (not get heavily penalized) if partner has a doubleton in our suit and about 6-7 HCP. We usually want to have a 6+card suit with good texture and a hand with good playing strength; a simple opening hand is not enough. This means that we will not be able to overcall at a high level on many hands we would have opened with if we had been the opening bidder.
As we are under more and more pressure to act at high levels and as we can overcall on fewer and fewer hands we will need to double (our other strength-showing action) more often to get into the auction.
Example 1
Versus a 3♥ preempt with
♠ K9843
♥ 7
♦ AQT6
♣ AJ4
We will double instead of overcalling 3♠. If the opponents had opened 1♥, we would have overcalled 1♠.
A takeout double becomes more flexible and needs to contain more hand types as the auctions get higher.
Example 2
Versus a 4♥ preempt with
♠ AQ74
♥ 83
♦ AQ
♣ KT962
We will be forced to make a takeout double (and hope that partner does not bid 5♦ or if they do, that they have a decent 5-card suit.) If the opponent had opened 1♥, we would have started with a 2♣ overcall.
Example 3
Versus a 4♠ preempt with,
♠ 4
♥ AQ97
♦ AQ3
♣ KT965
We use a double as more penalty-oriented (or card-showing) and 4NT is the call used to force partner to bid – similar to a takeout double. This 4NT bid for takeout, and it could be all three of the other suits or could be a “two-suited” takeout.
We do not Preempt a Preempt! Thus, we will define a jump overcall vs. a preempt to show a good long suit and a good hand.
Example 4
3♥ 4♠
This shows a very good 6-card to 8-card ♠ suit and some HCP – generally about 8.5 to 9 tricks. We have a good chance of making 4♠ if partner has one useful card. An example hand on which to bid 4♠:
♠ AQJT864
♥ 3
♦ AK8
♣ K7
These are hands that are almost good enough (or in some cases are good enough) to double and bid ♠ if RHO had opened 1♥. But partner is much more likely to pass our double at higher levels, so we don’t want to double with these very shapely offensive hands. By taking these hands out of the list of hands that make a takeout double, we also make it so that double contains more defensive hands and increase our chance of scoring well when partner passes our double, converting it to penalty.
Acting over high-level (destructive) interference from our opponents is difficult. It requires judgment, table feel, and experience to be successful in these auctions. You will notice that we have avoided putting HCP requirements on acting over interference at each level – vs. 2-level, 3-level, 4-level, etc. This is because HCP are important, but general playing strength (shape) is even more important when we are thinking about offense. Many of these auctions will have multiple very shapely hands at the table and times when both sides can make a lot of tricks declaring. Thus, dealing with this interference is a balance of risk and reward – should we come in or not? In these auctions, we will frequently be faced with difficult choices and we will be forced to do our best to describe our hand and allow us to land on our feet. These auctions will be a challenge and we will occasionally go for -1100 when we are unlucky or judge wrong. But with practice and judgment, we expect to do it less often than the other players!
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.
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.
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.
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.
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
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.
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.
There are many artificial systems for competing over the opponent’s 1NT opening bid. Systems like DONT or Meckwell are built around finding a fit and competing in the bidding as efficiently as possible – allowing us to show all our suits at the 2-level. One downside of playing DONT or Meckwell is when we show a 2-suited hand (like a Major + minor) then we do not know which suit is longer (either one could be a 5-card or 4-card suit). This can lead to missing a Major suit fit. There is another system, called Woolsey (named after its creator Kit Woolsey, one of the top bidding theorists) that is focused on finding Major suit fits while allowing us to compete as cheaply as possible. Let’s see how this system works.
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. Based on our partnership agreement this control showing bid either shows a 1st round control or a 2nd round control in the suit bid. Once we start the process of making control showing bids then we continue to do so to explore slam. 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”). Let’s see how this gadget works!
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.
When we have a minor suit fit, keeping the auction below 5-minor, while trying for slam is one of the advantages of minorwood — using 4-minor as an asking asking tool. 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.
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.
On some highly distributional hands when we ask for Keycards (or Aces) using 4NT, the opponents choose to bid over our 4NT bid in an effort to obstruct our communication and “get in the way”. We should be prepared for this type of interference and have agreements for how to communicate with partner (show our number of Keycards or Aces) in this situation. Here we look at how to do this.
5NT is not a common bid. We most frequently use it in Ace-asking auctions to ask for Kings. We now have another use of a 5NT bid in Grand Slam Force. But trying for a grand slam is a rare occurrence and we would like to use 5NT (specially a jump to 5NT) for another more frequently useful purpose. The modern approach is to play a jump to 5NT as a “choice of slams” to help up find the best small slam. Let’s see how this works.
We can use a 5-Major bid for something other than to end the auction. 5-Major can be bid concisely for a variety of reasons -- to take away bidding space from the opponents or to ask partner a specific question (which we call the “obvious question”). Let’s look at our options for how to make use of this 5-Major bid.
Minor suit slams are much harder to bid than Major suit slams. This is especially true after we open the bidding with 1NT (or 2NT). We start off the auction looking for Major suit fits and only then look for our minor suit fits after that. These Major suit showing bids are the cheapest bids and that means that our minor suit showing bids take up more space. We look at how we overcome this bidding challenge to bid good minor suit slams.
