DOUBLES… an Overview What they mean. When they should be made …and when they shouldn’t

The Effects of a Double ♠ It acts as a deterrent to frivolous bidding ♠ It increases the value of making a contract ♠ It increases the penalty gained by setting a contract  Doubles also can be used to substitute for a bid.

Negative Doubles ♠ After an opponent has overcalled your partner’s opening suit bid, your double (likely) shows: ♥ At least 4 cards in the other major and/or ♥ 4 cards or more in the unbid suits ♥ A good 7 HCP or more ♥ Little support for opener – otherwise, raise immediately ♠ Therefore, the bid of a suit generally shows 5+ cards and 5+ HCP. ♥ it is forcing for one round, if partner has not previously passed ♠ Negative doubles are generally made up to 3S ♥ If they force partner to a higher level, the strength of the negative doubler’s hand should be greater (12+ points if partner has to respond above 2NT)

Negative Double Quiz The bidding goes What do you do with the following hands? WNES P1♣1♣ 1♥1♥ ? 1. ♠ Axxx ♥ AQ ♦ QJxx ♣ Jxx 2. ♠ Qxxx ♥ xx ♦ QJxxx ♣ Jx 3. ♠ AKx ♥ xx ♦ QJxx ♣ Jxxx 4. ♠ xxxx ♥ xx ♦ Kxxxx ♣ xx 5. ♠ Kxxxx ♥ xx ♦ QJxxx ♣ x 6. ♠ KQxx ♥ Qx ♦ QJxx ♣ xx 7. ♠ KQxx ♥ Q ♦ QJx ♣ KQxx 1.3NT 2.DBL – negative 3.2 ♣ 4.Pass 5.1 ♠ 6.DBL - negative 7.2 ♥

Responsive Doubles ♠ After partner’s TO double, if RHO raises opener, even preemptively, your double is “Responsive” ♠ It requests partner to pick his best suit – it may be done with a weak, distributional hand ♥ If you hold ♠ Qxxxx ♥ Qx ♦ QJxxx ♣ x, make a negative double. If partner bids one of your suits, raise. If partner bids clubs, bid diamonds, showing diamonds and spades. ♥ With a better hand, ♠ KQxxx ♥ Qxx ♦ KJxxx ♣, if partner bids one of your suits, make a forcing Q- bid; slam is a possibility if partner holds the right 2 aces and a singleton heart

Responsive Doubles ♠ To be clear, in a sequence like 1 ♥ - DBL – 2 ♣ – ? ♥ DBL is penalty-oriented; ♥ Pass shows no interest, ♥ 2 ♦ or 2 ♠ would show at least 4 cards, and minimal values ♥ 2 ♥ is forcing, and shows game-going values ♥ 2NT is invitational, showing 9+HCP and stopper(s) in hearts ♥ 3 ♣ or 3 ♥ would be Western Q-bids, asking partner to bid 3NT with a partial stopper – Kx, Qx, Jxx, 10xxx ♠ Responsive doubles are generally played up to 3 ♠ or 4 ♦ (based on your partnership agreements). For example: 2 ♠ - DBL – 3 ♠ - DBL is responsive and asks partner to pick her best suit.

Responsive Double Quiz The bidding goes What do you do with the following hands? WNES 1♦1♦ DBL2♦2♦ ? 1. ♠ Axxx ♥ AQxx ♦ QJxx ♣ J 2. ♠ Qxxx ♥ xxxx ♦ QJ ♣ Jxx 3. ♠ AKx ♥ xxxx ♦ QJxx ♣ Jx 4. ♠ xxxx ♥ xx ♦ Kxxxx ♣ xx 5. ♠ Kxxxx ♥ xx ♦ QJxxx ♣ x 6. ♠ KQxx ♥ Qx ♦ QJxx ♣ Jxx 7. ♠ KQxx ♥ Q ♦ QJx ♣ KQxx 1.3NT (to play) 2.DBL (responsive) 3.2 ♥ (as requested) 4.Pass 5.1 ♠ (obvious) 6.2NT 7. 2 ♠

Take-Out Doubles ♠ Take-out Doubles – any direct-seat double shows ♥ the other 3 suits, ♥ a 2-suiter, ♥ or a strong hand ♠ Rule: A second double by the original take- out doubler is always a take-out double ♥ Note: this is only if partner passed over your first double

‘Balancing’ Doubles ♠ These are typically Take-out Doubles – any balancing double shows ♥ the other 3 suits, ♥ a 2-suiter, ♥ or a strong hand ♠ It may be passed for penalty (if partner has a trap pass) ♥ You hold ♣♦♥♠ Axxx ♥ AQxx ♦ xx ♣ Jxx and make a balancing double. ♥ Partner holds ♠ Kx ♥ Kxx ♦ AQJxx ♣ xxx, and passes WNES 1♦1♦ PPDBL The bidding goes

‘Balancing’ Doubles - continued ♠ These are typically Optional Doubles, showing ♥ A hand that has Opener’s suit and strength, but not enough or the wrong distribution to bid 1NT ♥ General strength, not wanting to let them play 1  ♠ It may be passed for penalty (trap pass) WNES P1♥1♥ P PDBL The bidding goes WNES PP1♥1♥ P 11 PPDBL or

Competitive Doubles* ♠ Occur when you and your partner have bid easily to game, and opponents have bid higher: ♥ Pass by your side says – “I can beat this contract” ♥ Dbl by your side says – “I need one outside trick from you to beat this contract – bid accordingly” ♥ A bid of a new suit is lead directing if they bid again, and forces partner to bid again ♠ *Note: only the Ace of the suit we have bid counts as a trick in these doubles (avoids double counting)

DSIP Doubles ♠ Do Something Intelligent, Partner. ♠ Over opponents’ interference, where both of you have shown values, even in cases where you have shown a fit, a double shows quick tricks and shortness in their suit rather than slow values. ♠ It indicates that you have enough points and wanted to make another bid ♠ It asks partner to make the decision to bid on or convert to penalty.

BIDDING OVER OPPONENT’S T/O DOUBLES ♠ 1 ♣ -DBL ♥ Pass ♦ 0-5 HCP with no 5-card suit ♥ RDBL ♦ 10+ with no better bid – may have clubs ♥ 1D/H/S ♦ shows 5 or more cards in the suit and is non-forcing ♥ 1NT ♦ 6+ HCP - To play – likely with clubs ♥ 2NT ♦ 5+ clubs with limit raise or better ♥3 ♣♥3 ♣ ♦ Preemptive raise ♥ 3NT ♦ To play ♠ Advanced Treatment ♥ 2C/D/H ♦ Transfer Bids with 3-card club support and invitational values or better ♥ 3D/H/S ♦ 7+ =card suit – no defense (1 ♣ can be short)

BIDDING OVER OPPONENT’S T/O DOUBLES ♠ 1 ♦ -DBL (assumes opener has 5 diamonds) ♥ Pass ♦ 0-5 HCP with no 5-card suit ♥ RDBL ♦ 10+ with no better bid (may have a forcing hand with diamonds) ♥ 1H/S ♦ shows 5+ cards in the suit and is non-forcing ♥ 1NT ♦ 6-9 HCP - likely 4 or more clubs ♥ 2C ♦ Shows at least 5 clubs and normally less than 10 HCP ♥2♦♥2♦ ♦ A simple raise – 6-9 HCP at least 3D ♥ 2H/S ♦ Preemptive, suit quality with little outside ♥ 2NT ♦ Invitational – 11+HCP ♥ 3C/H/S ♦ Splinter bids – show at least 4 diamonds, 9+ HCP and a singleton ♥ 3/4/5 ♦ ♦ Preemptive ♥ 3NT ♦ To play

BIDDING OVER OPPONENT’S T/O DOUBLES ♠ 1H-DBL ♠ Redouble = 10+ HCP and no fit ♠ 1S natural and forcing ♠ 1NT = transfer to C any strength or raise with values in clubs ♠ 2C = transfer to D any strength or raise with values in diamonds ♠ 2D = transfer to H - non constructive raise 3 card support ♠ 2H - (8 – 10 HCP) constructive raise ♠ 3H - pre-emptive 4 card support ♠ 2NT – Limit raise or better ♠ 2S/3C/3D - mini-splinter

14-Hand Quiz 14-Hand Quiz ♠ Assume your partner opens the bidding 1 ♣ and the next player doubles. How many points is each hand worth and what is your call? ♠ Q J 6 5 ♥ ♦ K ♣ 7 2 Points __ Call __ 6 1♦1♦ Did you subtract one point for an Aceless hand? It’s only important responding to NT. This is a reasonable hand and should be bid naturally.

2 ♠ Q J ♥ 9 ♦ J 6 4 ♣ 9 8 Points ____ Call ____ 9 3♠3♠ Remember to add 1 point for the 5 th Spade, and 2 points each for the 6 th & 7 th ! Partner opens 1♣, and the opponent doubles. The opponents have a heart fit. You have a suit you can play opposite a void. Your preemptive bid tells partner not to expect any defense.

3 ♠ K 7 5 ♥ Q 3 ♦ A K 3 ♣ Points ____ Call ____ 12+ 3♥3♥ Possibly enough for game. The 5-card club suit with lots of entries should set up. WNES 1♥1♥ DBL 2 ? Your 3 ♥ bid is a ‘Western Q” asking partner to bid 3NT with a partial heart stopper. (Qx or Jxx or better.) If he bids 3♠, just pass

4 ♠ 3 ♥ K Q ♦ Q ♣ A 6 4 Points ____ Call ____ 13 DBL This is a take-out double. If partner Q-bids or jumps the bid, try for game. Otherwise, pass WNES 1♠1♠ P2♠2♠ ?

5 ♠ ♥ A 3 ♦ Q J 5 2 ♣ Q Points ____ Call ____ 9 DBL This is a good hand for a responsive double, even without 4 spades. Let partner play it in his best suit. Don’t raise his bid. He’ll expect you have this kind of hand with your double. WNES 1♥1♥ DBL2♥2♥ ?

6 ♠ 8 5 ♥ J ♦ 8 5 ♣ Q Points ____ Call ____ 5 5♣5♣ Remember - a double by a partner who has already made a take-out double is still take- out. WNES 1♥1♥ DBL3♥3♥ P P P? Partner likely has a void in hearts and lots of quick tricks. This has become a pretty good hand.

7 ♠ 3 ♥ ♦ Q J ♣ K 4 Points ____ Call ____ 8 4 ♥4 ♥ You’re bidding partner’s heart suit. (*the 3- heart bid shows a singleton with invitational support of spades) WNES 1♠1♠ DBL3♥*3♥*?

8 ♠ J 10 3 ♥ 8 6 ♦ K J 7 4 ♣ K Points ____ Call ____ 8 3♠3♠ You don’t have to make a negative double with support for partner. A raise will show this hand – support with few tricks – not quite enough for game. WNES P1♠1♠ 3♥3♥ ?

9 ♠ A J 10 5 ♥ K Q 7 ♦ ♣ K J 6 Points ____ Call ____ 14 Pass Remember ‘Competitive Doubles?’ This is a forcing pass. It tells partner that you have the tricks to set the contract. She can then decide to double, if she has slow tricks, bid game with a singleton diamond and one ace, or slam with a void and an ace or 2 aces WNES P1♠1♠ P2NT 3♦3♦ 4♦4♦ 5♦5♦ ?

10 ♠ K Q ♥ 3 ♦ A 4 3 ♣ Points ____ Call ____ 12 5♠5♠ Partner is minimal and doesn’t know where to play (her pass over 4 ♥ is brilliant and likely shows only 3 spades). You can’t pass or double, as you don’t have enough defensive tricks for either action. If 5 ♠ isn’t making, 5♥ certainly is. WNES 1♥1♥ DBLRDBL4♥4♥ DBLP5♥5♥ ?

12 ♠ A J ♥ A J ♦ 10 7 ♣ 7 Points ____ Call __ _ 13 DBL DSIP Double. It says you have enough points/tricks for another bid, but it’s not clear what you should do. If partner bids 4 ♦, bid 4♥; Partner should correct to 4♠ with 3 Spades and 1 or 2 Hearts WNES P1♦1♦ 3♣3♣ DBL 4♣4♣ PP?

13 ♠ K ♥ A ♦ 5 2 ♣ 7 5 Points ____ Call ____ 8-9 DBL A nice, balancing double. Partner may be , and unable to take any action. Your double will get you to the right major suit. WNES PP1♣1♣ P 1♦1♦ P2♦2♦ P P?

14 ♠ A K Q ♥ A J 9 5 ♦ 8 5 ♣ 2 Points ____ Call __ _ 17 2 ♥2 ♥. WNES 1♣1♣ P2♣2♣ 2♠2♠ 3♣3♣ P3♦3♦ P 3♠3♠ P5♣5♣ ? Competitive Double. It says you need one trick from partner to set the contract. If she doesn’t have it she should 5♠ with 3 or more spades, or bid her best suit with less than 3 spades.
