In the expert world was is the common meaning of 3h here?

5-5 gf?
splinter long cl and short h?
5-4 invite?
other?


1d=1s
2c=3h?

[whereagles]

I think most play it as a GF 55.

[hatchett]

I play it as a 5-5 invite.

[gnasher]

I prefer to play it as 5-5 game-forcing, but I think the most common interpretation in England is as a splinter.

[kenrexford]

My vote is, "Most likely sequence to result in 6♣ down three." (Inside joke.)

[kgr]

With my regular partner:
splinter long cl and short h

[TWO4BRIDGE]

Jump-over-a-4th-suit bid = Splinter for Opener's last bid suit ( ♣ here )... unfortunately, not accepted universally, so you need prior discussion.

If you wanted to show a 5-5 GF, just bid 2H! ( 4th Suit GF ) and then 3H again.

If you had invitational values and a 5s/4h hand, I think you have to roll it into a 2NT rebid:
1D - 1S
2C - 2NT
- - - - - - - - - - - - - - - - - - - -
This is probably another advertisement to use XYZ .

I copied this off the old MSN Message Board back in Feb, 2005 ( I don't know if it still holds today ):

Taken directly from the Bridge World web site.
___________________________________________________________________
After a one-level new-suit response and opener’s simple new-suit rebid:

(a) two notrump or three of any suit previously bid is invitational;

(b) a fourth-suit bid that is either a reverse or a three-level bid is forcing to game;

(c ) a fourth-suit non-reverse at the two level is [default:] forcing for one round, and responder may pass if opener bids two of responder’s first suit, two notrump, or a non-reverse minimum number in one of his own suits { forcing to game [leaf] };

(d) a bid one level above a not-game-forcing fourth-suit bid is natural (five-five or more) and game-forcing (to invite with the same shape, responder bids the fourth suit cheaply twice);

(e) a bid one level above a game-forcing fourth-suit bid is a splinter;

______________________________________________________________________________

So, for the example given here:
1D - 1S
2C - 3H jump = natural 5/5, GF [ see (d) above ]

And that is because the following is forcing 1 round only ( F1 ) and NOT a GF:
1D - 1S
2C - 2H! ( F1 ) [ see ( c ) above ] .

[kenrexford]

Yep -- that's how I play it. 2♥ is forcing, but not GF. Hence, 1♠...3♥ is 5-5 GF.

But, discussion is key. And, discussion with everyone remembering the discussion also is key.

[JLOGIC]

I think 5-5 inv is the most common interpretation here, but I also like 5-5 GF

[TWO4BRIDGE]

And to get SPLINTERS into the mix ( using BWS criteria -- my post # 8 ) you have to:
A) go to the 4-level or

B) jump-reverse, if possible .
- - - - - - - - - - - - - - - - - - - - - - - - - -

So for the given auction:
1D - 1S
2C - ??

2H! = F1
2NT/3C/3D/3S = invitational
3H jump = 5/5 GF
4H double-jump = Splinter for ♣

- - - - - - - - - - - - - - - - - - - - - - - - - -
The folowing would be a reverse auction:
1D - 1H
2C - ??

2S! = GF
2NT/3C/3D/3H = invitational
3S jump-reverse = Splinter for ♣

Over here most common is GF 5-5. I haven't seen anyone play something else unless specifically discussed.

[peachy]

4th suit forcing, this can be agreed as 5-5 invit. Practical.

[FrancesHinden]

I play it as 5-5 INV (5-5 game force starts with 2h). I can't say what is 'standard' because most people haven't discussed it.

[mfa1010]

5-5 inv for us.

[Fluffy]

we play french style, as Frederick.

[OleBerg]

In Denmark 5-5 invitational has some following, but so does GF.

Personally I prefer it to show club-support with GF. (In the context, that 2♣ guarantees four.)

[whereagles]

There's considerable risk in playing this as invitational. What if there is misfit and invite is declined? You can't go back to 2NT...

Besides, if this is invitational, you won't have good enough suits to do it as much as you'd like to.
