Bidding
Doubling for penalties
Throughout this site I have emphasised that a double is usually for take-
You may or may not have agreed that the double guarantees a four-
In stating that it is primarily for take-
Still, there must be times when you will wish to use the double for its original intended purpose -
The first agreement must be that if you play take-
There are however a number of situations in which you can make a direct penalty double yourself.
The specific situations are:-
i) you and your partner have already agreed a suit;
ii) either you or your partner has overcalled in no trumps (but see below);
iii) you opened with 2NT, or an artificial 2NT sequence;
iv) either you or your partner has already made a penalty double or a penalty pass;
v) you opened with an artificial strong two-
vi) either you or your partner has redoubled partner’s opening one of a suit;
vii) partner doubled an opening one of a suit for take-

Double.
You are not much stronger than your opening bid, but you are full value.
You can stand any new suit from partner, and you have good defensive cards just in case he happens to have a decent hand with diamonds and decides to pass.

Double.
This is for penalties.
You have agreed a suit and so you cannot still be searching for one.
This sequence suggests a flattish hand with a high point-

You have overcalled in no trumps, and in so doing you have declined the opportunity to search for a suit fit.
You also clearly hold some well-
Partner has a holding in hearts behind the bid, and is at the top end for a hand which did not open.

Note that if responder were to pass at this point you would always (certainly at pairs) reopen with a penalty double after opening 2NT.

This might seem unlikely at first, but this is for penalties.
Partner has already passed your original double for penalties -
Partner holds hearts, you hold diamonds, and life is rosy.

This is for penalties, at least in principle.
Following your artificial strong two you will hold either the strong no trump hand, or a spade suit.
This is a favourite situation for psych interference -

An immediate double of an opening no trump is in effect for penalties.
Any subsequent double by either partner will therefore be penalty-

You made a natural overcall in no trumps and subsequently doubled
As a general rule any double following an overcall in no trumps by either member of the partnership will be for penalties. Certainly if you have overcalled in no trumps and partner then produces a double it will be for penalties -
On the other hand if you have made an overcall in no trumps which does not promise half the points in the pack and partner has shown no signs of life then you will usually not be strong enough to make a penalty double. In such a case the double must be for take-

You are not strong enough for 1NT.

You doubled -
There are two separate situations here.
The first is that responder raised opener’s suit.
In this situation partner’s double is usually played as responsive. In effect it is a return take-
The second situation arises when RHO responds in a new suit.
He could be in trouble. For a start he has bid one of the suits in which partner issued an invitation.
Of course, if you can see a certain major suit fit then you will probably bid it, depending on the vulnerability, but otherwise this might well be the time to punish them. In particular, when RHO responds in a major there is a fair possibility that he is trying to muddy the waters -

You opened 1NT
Many authorities will include auctions in which your partner opened 1NT in the list of penalty doubles.
That is up to you, but I much prefer an alternative use for this bid, and that is ‘showing values’.
Typically this would mean eleven or more points (invitational values -
This bid teams up particularly well with other aspects of the Lebensohl convention.
Judgement
The above concentrates on determining whether a double in any given situation is or is not for penalties.
At least as important is the judgement of when to double for penalties, as opposed to passing or bidding on.
Andrew Robson addresses this aspect of the game in a series of articles in English Bridge commencing February 2016.
A further excellent article on the matter, by Michael Byrne, is available to ebu members in the December 2020 edition of that magazine.
The opponents open at the four-
There is one further specific situation in which, by partnership agreement, double will also be for penalties.
Suppose that your opponents make an opening bid of 4♠.
You might wish to look for a slam -
The solution is to agree to double for penalties and to use 4NT as the take-
You may or not wish to extend this to an opening bid of 4♥, but there is sense in keeping such a double to promise four spades but with sufficient values for a penalty if a fit is not forthcoming.
It is unlikely that you will wish to use a double of four of a minor as anything other than a constructive take-
This agreement is easily summed up with the guideline that a double of an opening suit bid will be for take-
Doubling 3NT
This is a special case in which a double by the defender not on lead asks for an unusual lead. Follow this link.
There is, though, a possible exception to the above and that is when your opponents have bid in both minors.
I have found nothing about this in my researches -

You should come to a partnership agreement on the meaning of a double at this point.
My suggestion in this specific situation is that it should be for take-
