Room To Move

For musical accompaniment, I suggest the John Mayall classic "Room To Move" (link opens a new window). It's about five minutes long; coincidence, you say?

In this installment, you have the same hand in two different auctions. You are the dealer, vulnerable against not. After a strong 2  opening you are not playing any conventional responses (such as Jacoby steps or control steps) other than that a 2  response is "waiting".

Auction One: You and North both pass, partner opens 2 ♣,  and South passes.  Your call?

Answer: Bid 2 , waiting. You have great stuff for partner, with clear responses for anything she can bid. You don't have a strong five-card suit of your own. Slam seems very likely, and a grand slam is well within possibility. This is a perfect example of a hand where you want to give partner as much room as possible to describe her hand. Don't take away bidding space from partner by bidding 2 NT or 3 NT right now; give her some room to move.

Auction Two: You and North both pass, partner opens 2  , and South bids 2 . Your call?

Answer: Pass, waiting. You have great stuff for partner, et cetera, etc. Partner will get another bid, you don't need to keep the auction alive for her. So, don't steal bidding space from partner, give her some room to move. Also, unless you and partner have agreed otherwise, it is simplest to reserve Double for a clear penalty situation (but see the Bonus Minute and the Experts Moment below).

THE PRINCIPLE: After a strong two-club opening, give the opening bidder as much bidding room as possible. Don't take up bidding space unless you have to say something Really Important Right Now, like a strong five-card suit (personally, I prefer six). There will always be time later in the auction to show balanced strength, so don't crowd partner by bidding notrump now. Give the strong hand some room to move!

BONUS MINUTE:
What if your partnership normally uses step responses to show high card points (Jacoby steps) or control points? The standard way to handle interference is to use D0P1 -- pronounced "dopey" like one of the Seven Dwarfs -- which is short for "double zero, pass one." For the zero-th step, with 0-3 high card points or no control points, just Double. For the first step, Pass to show 4-6 HCP or one control point. For the next step, make the next available bid above the overcall, and so on. All of these responses must be Alerted. Note that this is the same structure you (should) use if the opponents interfere after a 4NT ace-asking bid.

EXPERTS MOMENT:
When the opponents interfere over a strong 2  opening, standard expert practice is to Double with a very weak hand and Pass (forcing) otherwise. This allows opener to simply convert the double for penalties if that seems like the last best option; else the partnership bids on normally. A balancing double by opener shows a balanced hand rather than a definite penalty double, in which case responder should take command from that point forward. This structure might be opposite of what most non-expert players would expect, so don't try it without first discussing with your partner!

Both sides vulnerable, you are the dealer. Your call?

ANSWER: Bid two notrump, showing a balanced hand with 18-19 HCP. Don't bid spades, and don't raise hearts. Your first priority with hands of this type is to show the strength and balanced shape. It is not forcing; partner may pass with a dead minimum hand and no useful shape.

THE PRINCIPLE: With a balanced hand that is too strong to open 1 NT (15-17) and not strong enough to open 2 NT (20-21), open one of a suit. If partner bids a new suit at the one level and you don't have four-card support, jump to 2 NT showing exactly this strength. Your bid promises a balanced hand with at least two cards in partner's suit but denies four-card support.

Some players call this bid a "jump-shift in notrump" but keep in mind that it is not forcing to game like other jump-shift rebids. I like to think of it as "one-and-a-half notrump".

Note that you have concealed a four-card major in order to show this strength and shape. If partner is 4-4 or better in the majors, she can rebid 3  to show her four-card spade suit and you can respond accordingly. Her 3  bid would not necessarily imply a five-card heart suit.

After your 2 NT call, new suit bids by responder are forcing for one round. A simple preference back to your opening suit is nonforcing and weak. If responder rebids her suit, it is forcing for one round and shows at least a five-card suit. (Note that some partnerships play this rebid as nonforcing.)

BONUS MINUTE:
  • If you play New Minor Forcing after opener's 1 NT rebid, you should play it after a 2 NT rebid as well.
  • If you play 1 NT Forcing in response to a major suit opening, raising the 1 NT to 2 NT shows a balanced 18-19 HCP along with the appropriate major suit.
  • There are several advanced conventions that can be used after a 2 NT rebid to reduce the ambiguity of responder's rebids. I suggest that you not explore these until you're sure which bidding problem you want to solve in this situation.

Exposing Emptiness

No problem hand this time around, just a quick lesson on a standard tool for ace-asking auctions.

Partner bids 4 NT asking for aces if you are playing plain Blackwood, or key cards if you are playing some form of Key Card Blackwood. How do you respond when you have a void?

There are several methods, but what follows is by far the most common; almost every tournament player on the planet will assume the following structure unless you've agreed otherwise. If somebody says they play "Void-Showing Blackwood," this is what they mean:
  • With a void in one of partner's bid suits, do not show the void. It's not a useful void.
  • With an even number of aces or key cards and a useful void, bid 5 NT.
  • With an odd number of aces or key cards and a useful void in a suit that is lower-ranking than trump, bid six of the void suit.
  • With an odd number of aces or key cards and a useful void in a higher-ranking suit, bid six of the trump suit.

Here are a few examples, all using plain Blackwood. Note that the responses will be different if 4NT asks for key cards instead of aces.

You hold K 10 7 5 -- A 9 8 5 2 K 10 6 5
Partner opens 1 , the auction goes 1  - 3   - 4 NT - ?
Bid 6 , showing an odd number of aces and a void in hearts.

You hold K 10 7 5 -- A 9 8 5 2 A 10 6 5
Partner opens 1 , the auction goes 1  - 3  - 4 NT - ?
Bid 5 NT, showing an even number of aces and a useful void.

You hold K 10 7 5 -- K J 9 5 2  K 10 6 5
Partner opens 1 , the auction goes 1  - 3  - 4 NT - ?
Bid 5 NT, showing an even number of aces and a useful void. Yes, same as the previous example; zero is an even number.

You hold K 10 7 5 -- A J 9 5 2 K Q 10 5
Partner opens 1 , the auction goes 1  - 2  - 4 NT - ?
Bid 5  showing one ace. Your heart void is not considered useful when partner has bid hearts.

You hold K 10 7 5 3 -- A J 9 K Q 10 8 5
Partner opens 1 , the auction goes 1  - 1  -3 - 4  - 4 NT - ?
Bid 6  showing an odd number of aces and a useful void in a higher ranking suit. You bid spades previously, and a diamond void would not be useful, so partner can work out that your void must be in hearts.

But what about kings?
Obviously, partner can't bid 5 NT to ask for kings after you've shown a void in response to 4 NT. If partner needs to know more, the customary continuation is that partner (the asker) bids a new suit at the six level to ask about the king in that suit. Responder tells by simply returning to the trump suit to deny that king, or shows that king by cue-bidding another king (below the trump suit) or 6 NT if that is next available non-trump bid.

Why not just count the void as an ace?
For partner's king to be good, she needs you to hold the ace in that suit, not a void. Also, it's very embarrassing when partner decides at the last minute to play the slam in notrump instead of a suit contract 😔
