Inversions after a X

[the hog]

Here is an interesting treatment my partner and I have adopted which may be of some interest:

 

1C (1D) 1H = 4+S, 1S = 4+H

 

1C (1H) X = 4+S, 1S = no 4S

 

1D (1H) X = S, 1S = no 4S

 

There are theoretical advantages to this:

 

Opener can rebid 1N - the strong hand is hidden

After a X opener can bid 1S, to show 3S and no stopper in the overcalled suit, or make his normal S raises. Again the opening hand is hidden.

 

Of course to play this, you need to be able to bid 1H on a 4+S suit after an overcall.

Of course to play this, you need to be able to bid 1S on a 4+ card suit after an overcall.

You mean bid 1H on 4+♠... not bid 1S on 4+suit,,,, :D

Yes, corrected.

Hi Ron!

 

 

-------

I am fan of such bids as you know. They are better solution than Bocchi-Duboin transfers at 1 level, because unlike them make opps bids with master suit more difficult in competition. Of course they can dbl 1♠ bid with 4+ cards in ♠, but for same bid they need more hcp and also can't distinguish between 4 and 5 cards in it. Will be nice if you can post here some examples of your play with partner, when they happen, despite of result. I am so sorry that can't play it, because my both favourite partners don't like idea of major inversion :D .

Hi all :)

 

I don't want to comment

 

1C (1H) X = 4+S, 1S = no 4S

 

1D (1H) X = S, 1S = no 4S

 

because in those cases I play Dbl with 4♠ and 1♠ with 5♠ but, don't you think that with

 

1C (1D) 1H = 4+S, 1S = 4+H

 

you give a supplementary chance to your LHO to dbl your 1♥ bid to show ♥ at an economic level ? :D

In natural system, 1C opener may not be the stronger hand. Not sure if this xfer will have much advantage,if any. Suppose the opener has 44 black suit, and responder bid 1S, showing 4+H, then what do you do? How to bid your spade? Responder may have both Majors.

Is this based on strong 1 ♣ opening bids ? Or just any regular opening bids. I play something similair with my pd when we play weak NT's but only after X. Looks interesting.

You bid 1N. This situation occurs ONLY after 1C (1D) of course.

 

Hi Misho, yes that is the major purpose - to make it difficult for the opps to bid that suit. We have only been playing it for a while, so do not have a lot of examples yet. Will keep you posted.
