Major-Suit Shade Card

Which color for the guest bedroom: Pineapple Frappe?  Kale Bisque? Hangover Sunrise? 

When you have a long, strong major suit -- one that will definitely be trump -- there is an equivalent "shade card" for bids to match the strength of your hand. Color preferences are a matter of taste; fortunately, the major-suit shade card is pretty much standard. 

To find the right shade, you must consider high-card strength and playing strength. For an example, let's use this hand from a recent Wydaho online game:
     AKJT8432  K  76  AQ

POP QUIZ: How many tricks is that spade suit worth?

ANSWER: Eight tricks. If partner has the queen, yay! If partner has three or more spades, yay! And otherwise, the queen might still be singleton or doubleton. Feel free to do the probability calculations, or just go with your gut feel that things will probably work out. Bottom line: You have an 87% chance for eight tricks, and a miniscule chance of only six tricks with this suit.

Okay, we have eight spade tricks. Add one-and-a-half tricks in clubs (partner has the king, or the finesse works, or an opening club lead), and a half-trick in hearts (partner has the ace or queen, or the ace is on our right and isn't played to the first round). That's ten playing tricks. You definitely want to be in game; slam is a distinct possibility!

How many ways can you open with a long strong major? We'll use spades for this discussion, but the same applies to a heart suit. You intend to unequivocally set the trump suit.

Shading from weakest to strongest:

  • Open 4 in first, second, or third seat. This shows 6 or 7 tricks (not vulnerable) to 7 or 8 tricks (vulnerable). Most important, this denies an opening hand. Partner will restrain her enthusiasm accordingly.
    Example: KQJTxxxx  xx  xx  x
  • Open 1, then rebid 4. This shows a full opening hand, but denies enough strength for a 2  opener. Thus a hand in the range of 11-15 HCP and about 7 or 8 playing tricks. Given your shortness in other three suits, it seems quite unlikely that 1  will be passed out.
    Example:  KQJTxxxx  Kx  Kx  x
  • If your partnership plays the Namyats convention, open 4 minor showing 8 to 8.5 tricks in the corresponding major with some potential for slam if partner has useful outside cards.
    Example: AKJTxxx  Kx  KQ  xx
  • Open 4 in fourth seat. This is not a weak preempt. You intend to get a plus score; otherwise you could have passed the hand out, or bid only two or three spades. The bid shows about 8.5 or 9 playing tricks and at most a poor 15 HCP; you can count on partner to have one trick for you somewhere. This bid denies slam interest. Even if partner has a maximum for her Pass, she won't make a move at this point.
    Example:  KQJTxxxx  Ax  Kx  x
  • Open 2 , then rebid 4. This shows a bare minimum 2  opener, at least 14 HCP with long spades and a hand worth about nine tricks. The message here is that partner should not pursue slam without three likely honor tricks. You have completely described your hand; it's up to partner to make any further move. (Regular partnerships should have an agreement on whether 8.5 tricks is enough for a 2 ♣ opening.)
    Example:  AKQTxxxx  KQ  xx  x
  • Open 2 , then rebid 3. This sets trump and asks partner to start cuebidding aces (or controls, per agreement) up the line. It shows a hand that is worth ten or more tricks, with at least 14 HCP. The key message is "spades are trump, show me controls." Show me the money, partner! You are the captain in this auction.
    Example: 
     AKJT8432  K  xx  AQ

Note what's missing here: There is no "open 2 , then rebid two" option. When you are absolutely sure about the trump suit and don't care about finding a secondary fit, don't let partner blab about her hand to the opponents. Take charge, set the trump suit, and if slam is in the picture get busy finding out about controls in the side suits.

THE PRINCIPLE: With a one-suited hand, the playing strength of the hand -- how many tricks can you expect -- is at least as important as the number of high-card points. A 2 ♣ opener may contain as little as 14 HCP if it is within one trick of game against normal splits. Using this shade card for single-major hands, partner will have a good idea of the strength of your hand and can proceed appropriately. It's a partnership game!

BONUS MINUTE:
The ACBL Convention Charts allow a very strong artificial 2♣ opening that contains:

i. at least 20 HCP; or 

ii. at least 14 HCP and is within one trick of game assuming suits break evenly among the other hands; or

iii. at least 5 Control Points and is within one trick of game assuming suits break evenly among the other hands.

After Partner's Weak Two

Partner's opening typically shows a six-card suit, probably two of the top three honors, 5-10 HCP, limited defensive values, and usually no four-card major on the side. Now what?

Ground Rule #1: Partner has, on average, king-queen-sixth and an outside queen. The most you can hope for is ace-king-queen-sixth, or king-queen-sixth and an outside ace; any hand stronger than that is an opening one-level bid nowadays.

Ground Rule #2: The weak-two opener will not bid again unless forced. This applies to any preemptive opening; exceptions are rare. Responder is the captain, and is in complete control of the rest of the auction.

With that background, here is a recommended structure for responding to a weak-two opening.
  • Support With Support! A raise is not invitational; a raise is simply continuing the preempt. With three-card support and no game interest, raise to three. With four-card support or more, raise to four (maybe just three at unfavorable vulnerability). Don't wait to see if the opponents will let you play at the two-level. There is no minimum point requirement for a raise. If you have no points at all, then the opponents can surely make game if not slam; take away their bidding space to make their lives more difficult. Consider raising even with honor-doubleton, particularly at favorable vulnerability and with poor defensive values.
  • If the player to your right makes a takeout double, all the more important to show support if you have it. If you have a fit, the opponents will never let you play your two-level contract doubled.
  • If you absolutely want to be in game across from as little as, say, king-queen-ten-sixth and out, just bid game. Note that this is indistinguishable from a weak jump to game with four-card support; make the opponents proceed at their own risk. Remember, opener is not going to bid again unless forced.
  • A new suit by an unpassed hand is forcing for one round. It suggests no fit, and at least a six-card suit of your own. Opener will raise your suit with honor-doubleton or more. Otherwise, opener can show a lower-ranking second suit (four or more cards) or just rebid the opening suit. Responder is in charge and will place the contract. This allows for responder to "rescue" a hopeless no-fit situation by bidding a new suit (forcing), and then rebidding it to play; this should be a good seven-card suit for a rescue. Note that a new suit by a passed hand is nonforcing.
  • If you want more information about partner's hand: Bid 2NT asking for a "feature", an outside ace or king. Opener shows an outside ace or king by bidding that suit (Alert!), or bidding 3NT with AKQTxx ("six solid tricks", Alert!). Otherwise, opener simply rebids her suit. A singleton or void is not a feature; responder might be looking for a outside entry in order to play in notrump, or a fitting honor in a suit of her own. The 2NT feature-ask does not indicate a fit for opener's suit. Responder will place the contract, not necessarily in opener's suit!
    • Many pairs prefer that opener not show a feature with a minimum hand; make sure you and partner are on the same page.
    • Some pairs prefer to use 2NT as the Ogust convention, asking about opener's overall strength and suit quality. Make sure you and partner are on the same page.
  • If you have a strong notrump opener or equivalent, you probably belong in game. Consider that if you had opened 1NT, partner will bid game holding an "average" weak two hand. Use the 2NT feature-ask if you think you need more information.
  • With no fit and no six-card suit of your own, be very cautious. Misfit hands belong in suit contracts; don't bid 3NT with no fit unless you can play all thirteen tricks from your own hand. With a very strong hand -- say, 20 HCP or more -- it's fine to put partner in game on a 6-1 fit.
Remember, opener will not bid again unless forced. Responder is the captain, and is in complete control of the rest of the auction. 

EXPERTS MINUTE:
If you have an exceptional hand and just want to go slamming, "Preempt Key Card" is a useful convention. It is standard practice among expert players. After an opening preempt, an immediate 4 bid by responder (Alert!) asks about key cards. Opener's responses are steps showing 0-1-1-2-2 as follows: 

      4 - no keycards
      4 - 1 keycard without trump queen
      4 - 1 keycard with trump queen
      4NT - 2 without trump queen
      5 - 2 with trump queen

All responses must be Alerted immediately in online play, or after the auction has ended in face-to-face play. Responder will then place the contract, not necessarily in opener's suit! 

Opener will never have three or more keycards; that would be an opening one-bid. Using Preempt Key Card the partnership can find out about keycards without ever going past five of the trump suit, and often staying at the four level with dismal hands.
