Three Diamonds

[kenrexford]

So, in some frustration last night, I tossed out a somewhat aggressive intervention into the opponents' sequence.

 

2NT opening (20-21), I overcalled 3♦ with xxx-Jxx-109xxx-xx. (We play natural overcalls here, in case you were wondering.)

 

Of course, the opponents had no way to find the double. Responder's next call, however, was 6♥, which made seven when an Ace was not cashed on opening lead (logically). The field result was either 6♥ or 6NT, making seven for the same reason.

 

The discussion afterwards, however, was somewhat interesting. Have you discussed what calls mean here?

My regular partner and I play natural overcalls of 2NT openings, but I have seen a number of good partnerships that play methods over 2NT openings similar to the types of methods that exist over 1NT openings.

was 3D a misclick? sod system discussion. just buy a better mouse

I treat it the same as 1NT (3m) .. so transfers at the 3-level.

[P_Marlowe]

we play the same structure as after a 1NT opening bid.

 

But I have yet to use it.

 

With kind regards

As long as you play penalty doubles in balancing seat, especially against jlall.

3x must be natural, you consume their space so much by doing so. Letting them have a cheap general strenght double is very wrong.

 

I have no particular agreements about what to bid after the interferation. Obviously 3♥ would be forcing and double take out, but no more agreements.

lol.

 

With partners I have discussed it with we play the same thing we do over 1N 3D which is:

 

X=takeout (like stayman)

3H=spades

3S=hearts

4C=nat

4D=5-5 majors

4H/4S=nat

 

Over 2N-3C it's just transfers, with 3S=diamonds, 4C=5-5 majors, 4D/4H=texas.
