After an IJS

[Phil]

Like many of you I play IJS (invitational jump shifts) in nearly all of my partnerships. In spite of this the follow ups are very fuzzy. Use 1♠ - 3♥ as a reference.

 

1. What is the best spade holding responder can have?

2. Is 3♠ by opener forcing?

3. What is 4m by opener? Cue (spades? Hearts? Ambiguous?) or natural?

4. Do you have a minimum suit quality requirement for 3♥?

 

Bonus question: what is your call with KJ9xxx A Kxx AKQ?

Look here Phil.

Thanks Zel, I missed that. Not a lot of consensus on whether or not 3♠ if forcing however.

With hearts, you virtually always have an invite available if you start with 1n, so I play that 1♠-3♥ is 0-1♠ unless the hearts are internally solid (i.e. if you have a hand that would raise spades after 1♠-1n-2♠, start with 1n). In the minors, you don't have so much flexibility, so there's no rule, but you can use your judgment and not bid 1♠-3♦ with ♠Hx and ♦AJxxxx.

 

I think 3♠ should be forcing, but I've also played NF with some partners, think it doesn't matter so much.

 

I would bid 4♥ on the example hand pretty much no matter what my agreeements were.

Who needs consensus? The person who suggested NF now had to play 4m natural and thus had no way to cue bid for hearts.

[Zelandakh]

I thought the consensus was clear enough for 3♠ to be forcing. It was just that once Justin stepped in and said he played it that way, noone else saw the need to come in on the matter. Looking back through the thread, I have to say that I still like my transfer scheme quite a lot; but it is untested since my (currently) preferred meaning for 1♠ - 3♥ is as a mixed raise.
