We are playing natural 2/1 and want to try the Rubensohl. GIB interfered with a 2 WJO.

We have agreed that the 3 level bids are transfer, so the bid 3x-1 showing 5+x, competitive or FG.
2NT are puppet to 3, either 5+ FG or INV in other suit (5+ if new suit).

So the typical bidding of S hand should be transfer to and bidding 3NT for the choice of game (if not trying slam).

Given N hand is such a powerful hand and want to FG against a competitive case (typically AQJxxx and out),
N try a move with 3 and we subsequently messed up the auction, not reaching the grand properly.

I would like to hear
- your favourable method handling this
- any suggestions/comments on our agreement.

Thanks.

Your agreements look good.

After North's 3, maybe S can try 5NT (pick a slam) and then raise 6 to 7.

But it's always easier with open cards :)

I prefer to play inv+ transfers. That way a strong opener usually knows when to investigate slam.

Playing your methods IMO North has an obvious 4 rebid. This is forcing because opener has to accept the transfer with any weak hand.

I would take 3 as either stopper ask or support as North should bid naturally with a strong unbalanced hand.

Thanks for the comments. Actually after rethinking of the problem, the "ambiguous" 3 can be more clearly pictured when we do some eliminations:

I guess some "natural" meaning of the bids, without further discussion, could be

4 = any hand with good fit to play opposite a competitive hand, may not have many points.
4 = big reverse hand
4 = big 1-suiter, FG
3NT = strong BAL - typically 18-19
3 = catch all, no distinct feature.

So all remaining is the 3, or even 4, 4NT, 5 to sort out the remaining hand types.
3 could be
- 8-9 tricks in m and seeking stopper (3NT probe)
- strong BAL but no stopper, no 3 card (we open 3244 in 1)
...

At the table N want to keep every option open (including playing of , , contracts) so the choice is 3.
If S bid 3NT over 3, will N thinks that S is just a competitive hand and have some chance to pass without trying slam?
So even 4NT have comes into the picture, but we have not thought of the 5NT yet :)
And N is already planned to pull 3NT to 4 if S really bid 3NT, and we all agree this has to be forward going.
