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.

Spear

When the auction begins 1m – 1NT (both bids by the opponents), it is rare that we want to compete in a minor suit. Usually in these auctions the opponents have the minors, since Responder has denied a 4-card Major. (Even if we have a 5+card minor suit, it could still be best to pass and defend 1NT.) In these auctions, it is effective to play a system geared towards the Major suits where we are most likely to have a fit. Spear is an artificial system that uses all the bids at the 2-level to show different Major suit hands. This gives us more options for how to compete in the bidding. Let’s see how it works.

Cuebids of Many Kinds

The modern game continues to create interesting auctions and we need to make sure to discuss how to respond to new situations with partner. Some of the most interesting (and useful) competitive bids are when we use a suit that the opponents have bid – called a Cuebid. Let’s take a look at cuebids of the opponent’s suit in a variety of different auctions and make sure we are on the same page with partner about the meaning of these calls.

Rosenkrantz Redoubles

When Left Hand Opponent (LHO) opens the bidding, partner makes an overcall, and Right Hand Opponent (RHO) makes a negative double, then Advancer is in the middle of a complex competitive auction.  Traditionally, a redouble in a competitive auction shows a strong hand (10+ points), but with everyone bidding it is not likely that Advancer is too focused on showing values.  Instead, we want to design our agreements to let us best describe the most common kinds of hands.  In this auction, Advancer having lots of values is not common.  Let’s see how using redouble as a conventional bid, called a Rosenkrantz Redouble, can be more effective than this traditional value-showing redouble.

Snapdragon Doubles

Bridge players keep finding more and more ways to use doubles, especially in low-level competitive auctions.  The traditional double by the Advancer is the responsive double.  This double applies when the opponents have bid and raised a suit and partner has taken some action in the middle (either a takeout double or a suit overcall).  But when Left Hand Opponent (LHO) opens the bidding with a suit, partner overcalls a second suit, and Responder bids a third suit, then a double by Advancer is not a responsive double.  It is a different kind of competitive double called a Snapdragon Double – a fancy name for another double that wants to compete in the bidding.   Let’s see exactly what this double shows.

Passive Opening Leads

Most partnerships that play Support Doubles have had a conversation about when they apply and when they do not.  Hopefully, we will have a conversation with partner about the follow-up bids as well. But one thing that many partnerships forget to discuss is how high support doubles apply and what a double at a higher-level show. Let’s look at support double auctions in detail to make sure we are on the same page with partner.

Passive Opening Leads

Active opening leads attempt to "go out and get" our tricks. Passive leads, on the other hand, attempt to just not give anything away or help Declarer. There are many different types of passive leads for many different situations. Here we take a look at several lead types and hands where a passive lead may or may not have the intended effect!

Guarding a Suit

Taking tricks with small cards is an important part of Declarer’s plan for making their contract. As a Defender, it is our job to do everything we can to stop that from happening. That means that suits that have potential winners, threat cards, must not be allowed to grow up into winners. We attempt to prevent this from happening by covering an honor with an honor (to prevent promotion) and by holding onto our cards in the opponent’s long suits – called guarding the suit
