This is a new twist on the sequence in mike777's recent thread: 2/1 and opener jump shifts .

A fellow named Carl ( JudyorCarl ) at rec.games.bridge suggested to "interchange"
the 3C and 3M in the opening title auctions:

The strong "2-suiter" hand Major/Clubs is shown as:
1M - 1NTF
3M!

And the strong invitational one-suited M hand is shown by:
1M - 1NTF
3C!
( One advantage I see in this sequence is it almost always would guarantee a rebid by Responder ).

What do you think of it and what follow-ups would you envision ?

[Phil]

Unnecessary switch.

If you want to play around, use 1♠ - 1N - 3♣ as artificial and a relay to 3♦, then:

3♥ = GF 5-4
3♠ = GF single suiter
3N = clubs

1♠ - 1N - 3♥ = 5-5 GF

I guess you can do something similar after 1♥ - 1N - 3♣, or possibly use 2♠.

[Fluffy]

I like the idea a lot, the proble obviously is that when you have clubs you've got to raise them at the 4 level, I like to raise them with 3♦, but the gain is nevertheless obvious, you have now room for the common strong 2M opening (I use 2NT rebid for that one).

[gordontd]

Playing transfers by opener in this situation solves this problem (I think, but am not certain, that the idea originated with Townsend/Gold).

It gives you various sorts of game-forcing single-suited rebids and allows your jump-rebids in new suits to be trusted to be natural. The price you pay is that you give up a natural 2C rebid (though you can transfer into 3C if you aren't completely minimum).

[mich-b]

One problem that I can see with the suggested switch is that after a natural

1♥-1NT
3♣

responder has a very useful option of 3♥ , showing a doubleton, which might be what the opener is waiting to hear if he has 6-4, 6-5, or concentrated 5-5.

If Opener bid instead , as suggested
1♥-1NT
3♥
responder does not have room to show doubleton support.

[gordontd]

You could of course play the switch by responder instead, so that after

1♥-1NT
3♣-

3♥ shows clubs and anything else denies them. You can use the remaining auction to sort out the degree of your heart fit.

The big 2-suiter hand: 1M - 1NTF, 3M! ( M/Cl 2-suiter , GF )
- - - - - - - - - - - - - - - - - - - -
There is a legitimate concern over a minimum Responder with 2 cards M . The 3M response is no longer available. Carl suggests 4M for that hand if you don't select 3NT:
" If opener has a genuine 2-suiter, the chances are very good that you'll play in one of his suits or in notrump.
And if reponder's stopper in one of the other two is less than solid, it seems you take your chances in (one of the ) suit(s) . "
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Carl then came up with a rather ingenious scheme ( IMO ) for the 3 card limit raise Response: a 6-ace RKC "TURBO" type "SHOWING" bid .

The "step" showing bids would include all except 3NT, 4C and 4M:

4D = 0 or 3
4oM = 1 (4 is impossible)
4NT = 2, no queen
5C = 2, 1 queen
5D = 2, 2 queens

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Here is an example hand I pulled from my somewhat limited files:
North . . . . . . . . . . South
x x x . . . . . . . . . . . . A K J T x
K x . . . . . . . . . . . . . A x
A T x . . . . . . . . . . . . x
K T 9 8 x . . . . . . . . . A Q J x x

- -. . . . . . . . . . . . . . .1S
1NTF . . . . . . . . . . . . 3S!
4NT! = 2, no Q's . . . . 6S *
___________________________

* could offer a 5NT = pick-a-slam ( 6C or 6S ) especially at IMPs
since a bigger fit in Cl ( unbeknown to Opener) may play better, and the Sp suit
may offer a place for discards. Also, chances are higher for a Cl-ruff
in a 6S contract with a big Cl fit.

If you want to adopt better methods after a forcing NT, try Gazilli. I have been very happy with it so far.

Agree 100%

For the 2 types of hands here, Gazzili 2C seems gets you to the "normal"
a) 3M level for 17+hcp one-suited and

3m level for big M/m hands.

The difference, however, is that Responder has first shown a "semi-positve" 8+ hcp hand, which is an advantage.

That's not entirely correct. Playing Gazzilly, you'll also know more about the holding in the OM. After a 2♦ positive, opener will bid 2OM with a 3 card suit, so going to 3-level immediately shows at most a doubleton there.

So when you're at the same level of bidding, you already know a lot more about both hands, not needing any switches... And if responder is weak, you'll know a lot more as well since he'll describe his hand pretty accurately.
