Competitive Doubles and Two-Suiters

Use negative, responsive and support doubles to find fits when the opponents interfere, show two-suited hands with Michaels and the Unusual 2NT, and handle interference over your 1NT with Lebensohl.

Module 3 of 12BiddingLevel: Advanced

At club level, the opponents bid on more than half the boards. Good competitive methods are worth more than any slam convention, because you use them every session.

In this module you’ll learn:

  • Negative doubles for responder after an overcall.
  • Responsive doubles after partner’s takeout double.
  • Support doubles for opener.
  • Lead-directing doubles of artificial bids.
  • Michaels cue bids and the Unusual 2NT for two-suited hands.
  • Lebensohl when the opponents interfere over your 1NT.

A note on alerting. Under the ABF Alerting Regulations, doubles, redoubles and cue bids of an opponent’s suit are self-alerting. You don’t alert them; the opponents can ask what they mean. This applies to every double in this module and to Michaels.


1. Negative doubles

Partner opens, and your right-hand opponent overcalls. A double by you is not for penalties. It’s a negative double: a takeout double showing the unbid major(s) and enough values to compete (about 6+ points at the one level, more at higher levels).

Auction What the double shows
1♣ – (1♦) – X Both majors, usually four cards in each
1♣ – (1♥) – X Exactly four spades (with five you’d bid 1♠)
1♦ – (1♠) – X Four or more hearts, but not enough to bid 2♥ (which needs five cards and about 10+ points)
1♥ – (1♠) – X Usually both minors, or values with no good bid
1♣ – (2♠) – X Hearts and the values to compete at the three level

Agree how high you play negative doubles. Many pairs use them up to 3♠ or 4♦.

Opener’s rebid

Opener treats the double like a response in the suit(s) shown:

  • With four cards in the major partner has shown, bid it (jump with extra values).
  • Otherwise make the most natural descriptive rebid.

What if you want to penalise them?

With a good holding in the overcaller’s suit, pass. With shortness in the overcalled suit, opener should usually reopen with a double, and you can then pass for penalties. This is why opener should be keen to reopen when short in the opponent’s suit.

Example

Partner opens 1♦ and your right-hand opponent overcalls 1♠. You hold:

♠ 8 6 3   ♥ K J 7 5   ♦ Q 4   ♣ A 9 6 2

You have 10 HCP and four hearts, but not five, so 2♥ would be wrong. Double: it shows the hearts and enough to compete.


2. Responsive doubles

The opponents open, partner makes a takeout double, and your right-hand opponent raises. A double by you is responsive: another takeout double, showing values and more than one place to play.

Auction What the responsive double shows
(1♦) – X – (2♦) – X Both majors, usually four cards in each, and enough to compete
(1♥) – X – (2♥) – X Usually both minors, or values with no clear suit to bid
(1♠) – X – (3♠) – X Values to compete at the four level, no clear suit

With one clear suit you’d simply bid it. The double asks partner to choose.


3. Support doubles

You open, partner responds in a major, and your left-hand opponent overcalls. A double by you shows exactly three-card support for partner’s major.

1♣ – (Pass) – 1♥ – (1♠) – X: “I have exactly three hearts.”

1♣ – (Pass) – 1♥ – (1♠) – 2♥: “I have four hearts.”

This tells partner whether you have an eight-card fit or a nine-card fit, which matters a lot when deciding how high to compete (Module 4). Most pairs play support doubles when the overcall is no higher than 2♥, and also use a support redouble when the opponent makes a takeout double instead of overcalling.


4. Lead-directing doubles

When the opponents make an artificial bid, a double usually says “please lead this suit”:

  • A double of Stayman (1NT – 2♣ – X) asks for a club lead.
  • A double of a transfer (1NT – 2♦ – X) asks for a diamond lead.
  • A double of a cue bid, a splinter or a Blackwood reply asks for that suit.

These are powerful in a slam auction: if the opponents control-bid a suit where you hold the king, a double tells partner which suit to lead.


5. Michaels cue bids

A cue bid of the opponent’s suit shows a two-suited hand, at least five cards in each suit.

Auction Suits shown
(1♣) – 2♣ Both majors
(1♦) – 2♦ Both majors
(1♥) – 2♥ Spades and an unknown minor
(1♠) – 2♠ Hearts and an unknown minor

After (1♥) – 2♥, if partner wants to know which minor you hold, they bid 2NT.

Strength. Many pairs play Michaels as either weak (about 6–11) or strong (about 16+). With a medium hand, overcall your higher suit and bid the other one later. With the strong type, bid again after partner’s reply.


6. The Unusual 2NT

A jump overcall of 2NT shows the two lowest unbid suits, at least five cards in each.

Auction Suits shown
(1♥) – 2NT Clubs and diamonds
(1♠) – 2NT Clubs and diamonds
(1♣) – 2NT Diamonds and hearts
(1♦) – 2NT Clubs and hearts

Unlike Michaels, the Unusual 2NT must be alerted. It’s a two-suited overcall, and it isn’t a cue bid.

Two-suited bids and Brown Sticker rules

Under the ABF System Regulations, a weak two-suited bid at the two or three level that may hold three cards or fewer in one of the suits is a Brown Sticker convention. Keep your Michaels and Unusual 2NT bids to five-five or better (some pairs accept five-four when not vulnerable) and you won’t need a Brown Sticker.


7. Lebensohl

Partner opens 1NT and the opponents overcall at the two level. You need to tell partner whether you’re competing weakly, inviting, or forcing to game. Lebensohl uses 2NT as a relay: partner must bid 3♣.

After 1NT – (2♥):

Your bid Meaning
2♠ Natural, competitive, not forcing
3♣ / 3♦ / 3♠ (directly) Natural and game forcing
2NT, then partner bids 3♣, then you pass To play in 3♣
2NT, then 3♦ To play in 3♦: a weak hand with diamonds
3♥ (directly) Stayman for spades, without a heart stopper
2NT, then 3♥ Stayman for spades, with a heart stopper
3NT (directly) To play, without a heart stopper
2NT, then 3NT To play, with a heart stopper
Double Penalties (or takeout, by agreement)

The memory aid is “slow shows”: going through 2NT shows a stopper in their suit, and bidding directly (“fast”) denies one. Some pairs play the opposite (“fast shows”); just make sure you and your partner agree.

Lebensohl responses are alertable in ABF events, and the forced 3♣ reply is conventional too.


Rules worth remembering

  1. After partner opens and RHO overcalls, double = negative (takeout), showing the unbid major(s).
  2. To penalise an overcall, pass and wait for opener to reopen with a double.
  3. Opener should reopen with a double when short in the overcalled suit.
  4. After partner’s takeout double and RHO’s raise, double = responsive.
  5. Opener’s support double shows exactly three cards in responder’s major; a raise shows four.
  6. A double of an artificial bid asks for that suit to be led.
  7. Michaels cue bids are self-alerting; the Unusual 2NT must be alerted.
  8. Lebensohl: slow shows a stopper.

Try these

1. Partner opens 1♣ and RHO overcalls 1♥. You hold ♠ K 10 7 3 ♥ 8 6 ♦ A J 5 4 ♣ 9 6 2. What do you bid?

2. RHO opens 1♦. Partner doubles and LHO raises to 2♦. You hold ♠ Q 8 6 4 ♥ K J 7 5 ♦ 9 3 ♣ Q 10 2. What do you bid?

3. You open 1♦. Partner responds 1♠ and LHO overcalls 2♣. You hold ♠ K 9 5 ♥ A 7 ♦ K Q 8 6 4 ♣ 10 7 3. What do you bid?

4. RHO opens 1♠. You hold ♠ 4 ♥ K Q 10 8 6 ♦ 7 ♣ K J 9 7 5 2. Which two-suited bid is best, and why?

5. Partner opens 1NT and RHO overcalls 2♠. You hold ♠ 7 4 ♥ 8 5 ♦ Q J 10 8 7 6 ♣ K 5 3. What do you do?

Answers

1. Double (negative). You have exactly four spades and enough to compete. With five spades you’d bid 1♠.

2. Double (responsive). You have both majors and about 8 points. Partner chooses the major.

3. Double (support). It shows exactly three spades. With four spades you’d raise to 2♠.

4. 2♠, Michaels, showing hearts and a minor. If partner bids 2NT to ask, you show your clubs. (2NT would be wrong: over 1♠ the Unusual 2NT shows the minors, not hearts and clubs.)

5. 2NT (Lebensohl), and when partner bids the forced 3♣, bid 3♦. That says “I want to play in 3♦ with a weak hand.”

What next?

  1. Agree with your partner how high your negative doubles go and whether you play support doubles.
  2. Watch for reopening doubles at your next session. Count how often a reopening double gives you a penalty or finds a fit.
  3. Move on to Module 4: Total tricks and sacrifices, which tells you how high to compete once you’ve found your fit.
