You hold:

Scoring: IMP

---

Bidding goes:
1♦ - P - 1♠ - P
1N - P - ????

We are playing 2/1 and it is assumed that we are playing nmf. You are playing with a partner you have never played with and have no "agreements" what do you do. You want to be in game but are unsure how to get there. If you bid NMF you get a minmum hand without 3♠ or 4♥.

I rebid 4♠.

NMF then 3♠, which should be 100% forcing... I don't see any reason to jump to game yet...

Same here. This fits what I play, 100% forcing and keeps 3NT in the picture.

I prefer playing 3♠ as forcing here, playing the xy-NT convention (a variation of 2-way check-back). However, most people over here play 3♠ as invitational over 1NT and has to go through 2♦ to GF. So, undiscussed, 3♠ would be invitational here (almost all tournament players here use the xy-NT convention).

If 3♠ was forcing, I'd rebid that; else GF and rebid 3♠ (whatever route that would be).

Glad I found the answer thanks all!

I saw this site http://www.fernside....econdRound.html and assumed it to be true ... It did seem to have a credible if outdated list of sources.

I think you are drawing an improper conclusion. It's perfectly playable to play the jump as forcing & going through nmf as inv. Just the other way is somewhat more popular at the moment. It's just like 2nd round jumps by responder in other sequences, most people now play them invitational, but a minority still prefer them as forcing.

The conclusion here isn't "don't believe everything you read" (although that is a good general rule), but "for bridge conventions, don't assume any site is comprehensive & conclusive about how a particular method is played", and "if there is more than one logically coherent method to structure rebids after a convention, people probably have played it more than one way, so you better discuss with your partner to be sure".

If you can bid 1N with a stiff as I like to play then I would just start with Nmf.

[whereagles]

A 4♠ wtp for me. If 1NT could be on a stiff spade, abstain. Refuse to play that way

Undiscussed, 3S could be anything. In my small sample, most play this as forcing.

According to the current edition (2001) of The Official Encyclopedia of Bridge:

Quote

Jump rebid by responder - These are jump bids short of game by responder at his second turn. The meanings of such bids vary widely. In traditional Standard American all such jump bids were considered forcing, whether or not responder rebids his own suit, supports partner's suit or names a new suit. In the modern style, all such secondary jumps are non-forcing unless they are in a new suit. Some players treat some as forcing and some as non-forcing.

The standard meaning of 1C 1H : 1S 3D is forcing in either style.  Other possible agreements: 5-5 invitational; splinter; or mini-splinter
