Responder's jump rebid
#1
Posted 2012-September-27, 19:24
1♦ - 1♠
2♣ - 3♠
as invitational, 6-carder & say 9-11 HCP
There is a case for treating
1♣ - 1♠
2♣ - 3♠
as forcing.
Who does that?
Does your answer depend on whether you play weak jump shifts?
Or form of scoring? (Might want to "correct" 2♣ to 2♠ at matchpoints, but not IMPs)
Do you play Bourke relay or similar?
TIA

I play this as forcing (with invites going through a 2 red rebid), but it's wildly non-standard. For me, it makes sense on it's own, plus it meshes well with my xyz type auctions where 3 level jump rebids are always GF (at the minimum).

I do, because I play weak jump shifts. I also like to play the Bourke Relay/3SF, but I will only use that with a 6crd major if the suit is too bad for a jump rebid.

1C - 1S
2C - 3S ( invitational )
1C - 1S
2C - 2D! ( cheapest new suit forcing, may be artificial )
2NT/3C - 3S ( GF )

that means a 2s rebid can be quite a wide range here.
2d would be art. gf.
1c then 2c could be quite lite.

But yes, it doesn't seem to be as common now as it was, except among Pavlicek devotees. Don't know why.

2♦ over 2♣ is also not a 1-1-1-3 auction. Siegmund was talking about a different set of auctions from the OP.
Happy New Year everyone!

What Mike says is our choice, sort of. However:
--9's are not involved in invitational bids except in response to a 1NT opening.
--The WJS inference mentioned by some doesn't apply because our ceiling for that is 5 pts.
--2S rebid 6-10
--3S NF 11-12.
IMO, the 10-count invites are fine after a 1NT rebid where at least 2-card support is guaranteed; but when the rebid is 2C there is no guarantee opener has any spades, and our 1-suited invites should be stronger.

Yes. If you play strong jump shifts without any clever stuff, you need 1♣-1♠;2♣-3♠ as invitational. Weak jump shifts make it easy to play this as forcing, because you can play 1♣-1♠;2♣-2♠ as constructive to invitational.

No, though the scoring might affect my decision about whether to make a weak-jump-shift on a particular hand.

In one partnership I play 2♦ as an artificial game-force, but that's not a determing factor in the meaning of 3♠.
