Double takeout

This hand is a little better than a minimum for this action.

I think the math bears out that this hand is a double of 1, 2, 3. or 4 (hearts raised to that level, or opened at that level). And that might seem strange to a lot of folks. I can't prove it, except by the fact that it has seemed to work over the years.

Double is takeout, similar to the X of 1. However there are two classes of hands that make this a somewhat different handtype:

1. Hands that double 1 for takeout but not 2-p-4 because they are too weak. You need a little more in your auction than after 1-?. Mind you, in my humble opinion the difference is not huge. I would say that with an ideal 4144 shape the difference should be about a queen, maybe a little more.

2. Hands that double 2-p-4 but do not double 1 because you have a better option over 1. For example if you have a simple little diamonds hand like
QJx
x
AKxxxx
Axx

You are happy to bid 2 with this hand of course if RHO opens 1 but the diamonds are not nearly enough for a 5 level bid. This does not mean that you have to be sure that 5 is a good contract if you bid 5. However, you still need to have good trumps to be able to suggest them for a 5 level contract.

More importantly, however, doubling on the 4 level is attractive because partner will always pass it if he is balanced. As the very boring adage says, it is easier to win 4 tricks than 11. Unless you are reasonably sure that your hand really really likes to play and prefers not to defend, you should offer the possibility of defending 4 doubled. Bear in mind also that bidding 4 is a completely different matter to bidding 5m. You should be prepared to routinely bid 4 in this position with most 6 card suits (and opening values or so). Bidding spades is a level lower and it has an excellent annoyance factor (oh no, they bid spades over hearts again).

So we saw that bidding a suit is getting harder and harder on higher levels. What other hand is there that we don't have a good alternative with? A 1NT overcall. Obviously we will have many 1NT overcalls that would never dream of acting over (2H)-p-(4H) but sometimes you are so strong that you can't afford to defend 4H undoubled (which is what will happen 99% of the time when you have, say, 18) because you can easily have game. So you double and you hope partner has a suit that he was too weak to mention or that he passes and you hopefully get maybe 300 out of 4x, or something.

AJxx
AJx
Axx
Kxx

this is a great hand and a simple 1NT bid over 1 but you're stuck over 2-p-4. Partner could have a weak two bid of spades like

Kxxxxx
x
xx
Axxx

and we make 5 spades but if we don't double they will concede 50 or 100. We are just too strong to pass. To reiterate, not all 15-17 counts with a heart stop are eligible to this double, in general look for as few hcp in hearts as possible and as many Aces and Kings as posible.



As a summary: (I don't expect anyone to have read this far)

Doubling of 1 and 2-p-4 are the same class of hands except:

1. Sometimes you have to pass in the second case a hand that you'd doubled with in the first case because you're too weak. The difference is about a Queen or a King.

2. Sometimes you have to double in the second case that had a better option in the first case.
*Bidding a suit over 1 has looser criteria than over 2-p-4
*You have a natural 1NT available in the first case but not in the second case (4NT would be two-suited, usually with the minors).
... and I can prove it with my usual, flawless logic.

X for takeout. We are not at the 5 level yet, Kathryn.

gwnn are you croatian or something? you have a perfect double of 1 with 3163!.

seriously, I'd rather double with this shape, not sure if this is standard or not, I'd bid 1 with 5143 though and double at higher levels so the point is still valid for me.

A textbook double and a textbook 5C bid over the double with partner's hand leading to the perfect spot. WD.

partner expects to be able to pass with weak hands fortunately we are just strong enough to risk an X because of our positional values

Easy double, just as we would do if RHO opened 4.
That's impossible. No one can give more than one hundred percent. By definition that is the most anyone can give.

Hmmm...I thought he was a Lavalander (maybe Ashlander would be closer) :)

Dbl (definitely takeout), then partner may have a 4 or 5 level decision :(
