Our TWiB lesson is about Balancing NT and some other balancing options. We look at auctions where we can balance with 1NT with a wider range of values, and we look at what to do with some hands where 1NT isn't an option. 

We start with a look at the modern evolution to more aggressive 1NT opening bids -- 14 -16 1NT Openers.  We discuss how you bid if you agree to play this, both as an Opener and as Responder. 

There are certain auctions where we have made a bid that has “fully described our hand” and we leave the bidding up to partner.  In auctions like these, for example when we have opened the bidding with a preempt at the 2-level or 3-level, then we usually are not very sure of what partner has for their bid and we want to leave any further decisions up to them.  But sometimes we have more shape than partner expects or our instincts tell us that is right to bid on.  When that is the case we do NOT want to just take over and bid again – we told partner we would not bid anymore after our first bid.  In an auction like this we can use a Double as a conventional bid saying “I want to bid more”.  This is called an I Want to bid Double and it applies in very specific situations

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.

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.

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.

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.
