When should a new suit be forcing after a semipositive response to 1C? We have the agreement that jump bids and cue bids are forcing. Assume each response to be a semipositive.

1C (1D) 1H P is 2C forcing? a 2/1

1C (2D) 2H P is 2S forcing? a 2/2

1C (2D) 2H P is 3C forcing? a 3m/2

1C (2D) 2S P is 3H forcing? a 3M/2

So far we've payed each as nf and it's worked out. Seems like it shouldn't but perhaps the nf hands are just more common. Thoughts?

Still hoping for advice here.

I'm thinking 3M ought to be forcing.

I'm also wondering whether a 1-step (suit) bid as a GF start might make sense. Then other suit bids are nf.

Minors force; majors not.
What upside to trying to get to a 2m contract?
Besides force stays low to show Major next - step up from 2M nf, -step down from M-GF.
Whereas 2M/3M may be best score.

LHO overcalls, pd shows a semipositive

.....jumps, cues, and 3M forces


pd shows a nondescript semipositive, RHO overcalls (or raises LHO)

.....P-balanced or penalty (forcing through 2S)
..........dbl-takeout
..........2N-denies shortness
..........other-natural
.....dbl-takeout
.....suits through 2S-nf
.....Rubensohl, transfer into their suit is Stayman

pd shows a suit semipositive, RHO raises LHO or bids a new suit


.....jumps, cues, and 3M forces

Semipositive responses are forcing at the 1-level but nonforcing at the 2-level, right?

In that case I think I would play a 2/2 rebid by opener as nonforcing and everything else as forcing.

Btw, can you assume that the 1/2♦ overcall is natural? I suppose if opps want to psyche they would rather psyche a major, but some people play weird stuff against 1♣.

After partner has shown a semipositive (suit or nondescript) and RHO overcalls, double ought to be penalty because there is too much chance that RHO is stealing our suit or more likely that LHO will remove to his own suit...which means that we don't get to show our penalty double.

So again, for RHO interference after partner's semipositive....

P-forcing, takeout or balanced, the opponents can't play anything below 3C undoubled....
.....partner's balancing double is directionless with usually 3 of their suit or Hx and a max
.....partner's bid of 1N or 2N is takeout with 2 or fewer of their suit
dbl-penalty
1N-natural, nf
suit of 2S or below...nf and not invitational

Rubensohl (transfer Lebensohl) starting at 2N. If opener transfers into a suit that he could have bid at the 2-level, then he has an invitational hand or better. If he could not have bid at the 2-level, then he is competing or plans to GF.

Acceptance of the transfer does not show a fit and is nf.

Opener may transfer into partner's suit...and bidding partner's suit at the 3-level shows the next higher.

The trickier part is against LHO interference. Here we want LHO on lead, especially as it's into the big hand. After partner makes a semipositive response...

cue is a GF
jumps are invitational with usually 6 cd suits
minimum bids could be invitational if 2-suited but are nf

We play F2NPR: a new suit is forcing to 2N, preference or rebid. Simple, easy to remember, seems to be as good as any other rules (all of which are more complex or less efficient).

I can see how that works well for 2-suited hands. It's nice to have some nf bids, too, because then more meaning is attached to responder's rebids...


1C (1S) 2C (natural semipositive) P 2S P 3S

means one thing if 2S if f and something else if 2S is nf
