Action after partner’s direct seat takeout double:

KQ107 AJ98 J765 2
1 -

Double. Perfect.


J2 K876 A765 A102
1 -

Pass. You can’t support spades. Don’t overcall in a lousy four-card suit..


KJ2 KQ10 J76 AQ108
1 -

1NT. A 1NT opening with clubs stopped.


AQ1076 A43 32 Q76
1 -

1. The five-card major is the main priority.


K2 J654 AK2 Q1087
1 -

Pass. You don’t have support for spades.


AQ10 AQJ 54 J8765
1 -

Double. Prefer to bring all three suits into play rather than overall in a five-card minor (and a lousy one at that).


QJ9 Q76 Q654 KQJ
1 -

Pass. This hand is “12–17” but is ugly with wastage in the opponent’s suit. Your holding in the other major is poor and partner will have to show his suit at the two level.


2 A1087 A1086 K1085
1 -

Double. Only 11 HCP, but perfect shape.

KQ107 2 AQJ7 A1087
3 -

Double. Perfect.


AQJ1087 2 K102 Q32
3 -

3. True, you can support the other suits, but this hand is about spades; just overcall.


KQ AQ A1032 QJ872
3 -

3NT. Natural. If you double, guess what partner will bid.


KJ106 2 KQ102 A765
1NT -

Pass. There is no such thing as a takeout double of a 1NT opening.


AKQJ AKQ J102 876
1NT -

Double. In standard, this shows a strong hand – you have it.


KQJ9 A32 A32 654
4 -

Pass. Double is not for penalty. If you double, partner likely will pull. Don’t expect to hold such a hand against a four-level preempt.


2 AQ108 AKQ2 Q1072
4 -

Double. If partner has shape/offense, he will pull and be happy with your dummy. If partner is flat, he will pass and you will lead a high diamond and hope to set them.


2 A2 AQ1087 KJ1072
4 -

4NT. A 4NT overcall shows a two-suiter (at least 5–5) and a good hand. The suits are presumed to be the minors.

KQ10 AQ102 KJ Q1087
1 -

1NT. You have a hand that would have opened 1NT and you have their suit stopped; overcall 1NT.


AK10 AQ102 KJ Q1087
1 -

Double. Too strong for 1NT. Double and then bid notrump.


AQ876 1042 AK54 3
1 -

1. A simple overcall. Not strong enough to double and then bid again.


KJ8762 A AQ2 AJ2
1 -

Double. Too strong for a 1 overcall. Double and then bid spades.


87 AKQ10 AKJ2 Q87
2 -

Double. You have both 18-plus and support for all three unbid suits.


K82 K2 KQ108 AQ76
2 -

2NT. This shows the high end of a 1NT opening with their suit stopped.


AK10876 2 A65 K65
3 -

3. Not strong enough to double and then bid spades.


AKQJ10 32 AKQ10 54
3 -

Double. Too strong for a simple overcall of 3.

54 AKJ10 A10865 32
1 - Pass - 1 -

Double to show roughly 12–17 total points and the other suits.


AKQ A2 1087 106543
1 - Pass - 1 -

Pass. You don’t have the right shape for a takeout double.


AQJ 543 AJ54 AJ10
1 - Pass - 1 -

1NT. This is like a 1NT opening with both of their suits stopped.


A2 AQ10876 K876 2
1 - Pass - 1 -

2. Prefer overcalling in a five-plus-card major to making a takeout double.


AQJ106 32 A107 J108
1 - Pass - 2 -

2. Same explanation as above.


10876 2 AK76 A1076
1 - Pass - 2 -

Double. Takeout - don’t let them play in 2 (do this even with a bit less).


5 AQJ7 AK1076 K32
1 - Pass - 2 -

Double. If partner bids clubs, so be it.


K2 A54 AKQJ762 K
1 - Pass - 2 -

3NT. Natural, expecting to make it (don’t worry about the clubs; you can’t wait for perfection).

Q54 Q54 Q54 J765
1 - Pass - Pass -

Pass. Sometimes you defend against a one-level contract


AJ2 Q102 Q765 K102
1 - Pass - Pass -

1NT. In balancing seat, about a king less than a direct notrump overcall.


KQ76 K1076 J876 2
1 - Pass - Pass -

Double. “Borrowing” a king.


A10876 J2 A43 Q65
1 - Pass - Pass -

1. With a five-card major, prefer overcall to double.


AKQ107 A1076 2 A43
1 - Pass - Pass -

Double. Too strong for an overcall, especially in balancing seat.


AKQ1076 2 AJ10 J95
1 - Pass - Pass -

2. Intermediate in balancing seat. Good six-card (or longer) suit.


A1087 2 A876 Q765
2 - Pass - Pass -

Double. “Borrowing” a king.


KQJ76 2 A1076 432
2 - Pass - Pass -

2. With a five-card major, prefer overcall to double.

43 8762 10765 J43
1 - Dbl - Pass -

2. Choose your longest suit. You are showing 0–8, so you are within range. Don’t pass in fright.


K6 A32 K10654 1097
1 - Dbl - Pass -

3. Make sure to jump to show more than 0–8. This bid is not forcing; partner can (and often will) pass.


AQ876 AK42 43 32
1 - Dbl - Pass -

4. Be sure to reach game (a cuebid is also a possible call).


K654 32 K1087 654
1 - Dbl - Pass -

1. Prefer to show the major.


A2 A1087 K1054 832
1 - Dbl - Pass -

2. Too much for only 1.


Q765 AQ65 A Q1082
1 - Dbl - Pass -

2. Cuebid (partner has to bid again) and try to explore for the correct game.


Q876 43 32 87654
1 - Dbl - Pass -

2. We will discuss taking out the double to notrump next (Spoiler: this hand isn’t strong enough).


A432 KQJ8 J105 32
1 - Dbl - Pass -

3. Make sure to bid more than 2 which would be only 0–8. This jump is 9–12, invitational and doesn’t promise five cards in hearts.

A2 J76 10432 KJ98
1 - Dbl - Pass -

1NT. More descriptive than bidding diamonds.


KQ109 Q87 32 A876
1 - Dbl - Pass -

2. Don’t skip a very playable major to show points and stoppers.


102 A102 QJ987 AQJ
1 - Dbl - Pass -

3NT. Where you want to be. Shows opening bid strength (and their suit stopped).


KJ10987 2 AQJ9 32
1 - Dbl - Pass -

4. Make sure to reach game.


Q1087 32 J876 KQ2
1 - Dbl - Pass -

1NT. More descriptive than bidding diamonds.


QJ1098 A2 543 543
1 - Dbl - Pass -

Pass. A rare “penalty pass.”


A2 A543 AQ1087 32
1 - Dbl - Pass -

2. You could guess to jump to 4, but the cuebid allows more exploration (picture partner with: 87 K76 KJ92 AK74 , where 3NT or 5 are better contracts than 4).


A765 KJ987 3 J108
1 - Dbl - Pass -

3. Invitational.

10876 543 108762 2
2 - Dbl - Pass -

2. Don’t pass (even with your five diamonds you don’t have enough defense).


AQJ1087 2 654 KJ2
2 - Dbl - Pass -

4. Enough to want to be in game.


A765 A765 A32 Q3
2 - Dbl - Pass -

3. No rush to guess at the final contract. Enlist partner’s help.


82 KJ76 KJ86 872
3 - Dbl - Pass -

3. Not enough to jump. Prefer the major.


KJ2 K2 J10976 KQ10
3 - Dbl - Pass -

3NT. More practical than bidding diamonds.


54 A2 J765 QJ987
3 - Dbl - Pass -

Pass. At any vulnerability, collect a big number.


Q32 J76 A1076 J76
4 - Dbl - Pass -

Pass. Don’t take out at this high level without a lot of shape.


J9876 32 32 J1087
4 - Dbl - Pass -

4. Generally, bid 4 over 4 if it is in the ballpark.

  • Pass = Says nothing – could be zero points – just a hand that has nothing to say
  • Suit Bid (non-jump) = Natural(four or more cards) 5–8 total points
  • Jump-bid = As if RHO passed
  • Notrump = As if RHO passed

A32 J32 765 Q642
2 - Dbl - 4 -

Pass. Not enough to come in at this level.


A10876 2 A1076 Q32
2 - Dbl - 4 -

4. Nice hand, nice suit – you have plenty of offense and a reason to come in.


AJ2 32 K1076 K875
2 - Dbl - 4 -

Double. A “responsive” double showing “cards” (not hearts or penalty).


Q765 Q854 432 32
1 - Dbl - 1NT -

Pass. Not enough to come in at this level.


A103 Q8653 3 10876
1 - Dbl - 1NT -

2. Enough reason to make a free bid.


A654 Q10765 2 K102
1 - Dbl - 1NT -

3. Too much for only 2 (but not enough to insist on game).


J875 Q32 J32 654
1 - Dbl - 1 -

Pass.


A1087 54 K1076 654
1 - Dbl - 1 -

1.

There are two situations where thedoubler can take a second action:

  • With the “big” double — 18 or more HCP and a five-card or longer suit (if you rebid a suit)
  • Partner has shown values

AQ65 A32 32 AJ87
1 - Dbl - Pass - 1
Pass -

Pass. Not enough to bid again facing 0–8.


K2 AQJ7 654 AKJ5
1 - Dbl - Pass - 1
Pass -

2. Showing the big double (extras) – inviting partner to go further. Be careful not to bid 3 (or more); partner could have nothing.


AK AKQ2 A32 J1076
1 - Dbl - Pass - 1
Pass -

3. Even stronger than above, begging partner to go to game with even a little bit (like a king).


AK32 A43 AJ3 K108
1 - Dbl - Pass - 1
Pass -

1NT. Showing more than a 1NT overcall (roughly 18–20). Not forcing. Don’t make the common error of jumping to 2NT with this hand (which would show about 21–23).


A1087 3 AQ7 Q6543
1 - Dbl - Pass - 1NT
Pass -

Pass. You showed yours and partner showed theirs.


QJ109 43 AQJ7 AKJ
1 - Dbl - Pass - 1NT
Pass -

2NT. Invitational facing 6–10.


A10872 2 AQ4 J1076
1 - Dbl - Pass - 1NT
Pass -

No answer, as this is a trick question. You should have overcalled 1 instead of doubling. 2 here would show the big double (18 or more).


AQJ108 A32 2 AQJ2
1 - Dbl - Pass - 1NT
Pass -

2. Showing more than a 1 overcall (18 or more) and forcing facing 6–10 HCP.

2 1087652 J543 32
1 - Dbl - Pass - 1
Pass - 1NT - Pass -

2. Must be better to play in hearts than notrump (this doesn’t show any strength).


Q108 Q1076 K2 9876
1 - Dbl - Pass - 1
Pass - 1NT - Pass -

3NT. Partner has a good 18 to 20, which means you should go to game.


QJ54 Q32 J32 765
1 - Dbl - Pass - 1NT
Pass - 1NT - Pass -

Pass. You have a minimum for the 6–10 you showed.


K1098 A2 J108 10954
1 - Dbl - Pass - 1NT
Pass - 1NT - Pass -

3NT. With the good spot cards, this 8-count should be considered a “maximum.”


J876 2 8765 Q762
1 - Dbl - Pass - 1
Pass - 2 - Pass -

Pass. 2 is nonforcing. Leave well enough alone.


A987 KJ2 8765 32
1 - Dbl - Pass - 1
Pass - 2 - Pass -

4. You have a huge hand opposite partner’s big hand with hearts.


2 Q10876 432 J1076
1 - Dbl - Pass - 1
Pass - 3 - Pass -

4. Partner is begging you to go with any crumb – your crumbs (especially the fifth heart and the singleton) are enough.


KJ76 J1087 J102 J2
2 - Dbl - Pass - 2
Pass - 2NT - Pass -

3NT. Partner has a good 18 to 20, which means you should go to game.

J1092 2 AQ102 K1082
Pass - 1 - Pass - 1NT -

Double. Not completely safe, but you have the perfect shape to get into the auction.


A2 QJ1098 K432 32
Pass - 1 - Pass - 1NT -

Pass. Don’t even dream of anything else.


K1098 AQJ2 K1032 2
1 - 2 - Pass - Pass -

Pass. If your black suits were reversed, you could double.


2 K1087 AQ765 A32
1 - 2 - Pass - Pass -

Double. When short in their suit, you don’t need extras to make a reopening double.


AQ2 2 AQ1076 AK102
1 - 1 - Pass - 2 -

Double. Shows something like this (although you don’t have to be this strong).


3 82 AKQ8763 K102
1 - 1 - Pass - 2 -

3. Straightforward – not the hand for a double.


KJ876 QJ2 KQ32 2
1 - 2 - Pass - Pass -

Pass. Swap the hearts and clubs and you could double.


KQJ9876 2 QJ8 K2
1 - 2 - Pass - Pass -

2. True, you are short in hearts, but if partner leaves it in, would you be happy?
