TWiB Lesson #572 (6 of 9)
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 LOTT bidding is especially effective when our side has a 9+card fit. 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.
TWiB Lesson #574 (8 of 9)
Jumping in the auction eats up a lot of bidding space, which is likely to make communicating with partner more difficult. Since our jump bid may make future communication more difficult, it should have a specific meaning. When partner opens the bidding, Responder’s jump shifts can be used to show a variety of different types of hands. We need to decide, as a partnership, which ones we want to use. We will choose different agreements for different situations.
TWiB Lesson #544 (4 of 9)
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. Thus, we construct our bidding system to allow us to explore game and make constructive bids, not just be destructive.
TWiB Lesson #545 (5 of 9)
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.
TWiB Lesson #546 (6 of 9)
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.
TWiB Lesson #541 (1 of 9)
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.
TWiB Lesson #542 (2 of 9)
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.
TWiB Lesson #543 (3 of 9)
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. 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.

TWiB Lesson #547 (7 of 9)
When we open the bidding with 1NT if an opponent makes a penalty double, we are less likely to be 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.
TWiB Lesson #548 (8 of 9)
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.
TWiB Lesson #549 (9 of 9)
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.
TWiB Lesson #532 (1 of 9)
When we are in a game forcing auction and the opponents interfere (usually to sacrifice) it is clear that we are not going to go quietly and just let them steal the contract. If the opponents bid over us, then we will either double them and defend or bid on to our game. Forcing Pass is an agreement used to help us work together with partner to make a good decision about which to do.
TWiB Lesson #533 (2 of 9)
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.
TWiB Lesson #534 (3 of 9)
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.
TWiB Lesson #535 (4 of 9)
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.
TWiB Lesson #536 (5 of 9)
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.
TWiB Lesson #537 (6 of 9)
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.
TWiB Lesson #538 (7 of 9)
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.
TWiB Lesson #539 (8 of 9)
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.
TWiB Lesson #540 (9 of 9)
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. 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.
TWiB Lesson #524 (1 of 8)
One of the most important parts of bridge is raising partner. We try to raise Opener whenever possible. We may choose not to support partner immediately if we feel we have something more pressing to communicate, but in general we strive to “support with support.”
TWiB Lesson #525 (2 of 8)
When partner opens in 3rd or 4th seat and we have a good hand, we do not want to go jumping around to show it – partner may have no game interest for their opening bid. We want to have an effective way of describing our good hands cheaply when partner opens in 3rd or 4th seat.
