Kokish Over Strong 2C

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.

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.

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.

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.

5NT Choice of Slam

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.

5-Major Obvious Question

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 After NT Openings

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.

Forcing Pass Auctions

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. — “Forcing Pass.”
