You hold ♠A5 ♥AJT74 ♦AK854 ♣6. Partner opens 1♣, you respond 1♥ and partner rebids 1♠.

What is your next bid?

[jillybean]

2♦ wtp, I'll bid 3 next time.

[mich-b]

3♦ - 5-5 GF.

Some people play direct 3♦ as invitational, and bid 2♦4sf and 3♦ on the next round to show a GF 5-5. We prefer to use that sequence as "5th suit forcing = genral force" with a hand like :

Qxx
AKJxx
xxx
Kx

1♣-1♥
1♠-2♦
3♣-3♦

[jmcw]

Jump in the 4th suit shows an invitation distributional hand. 4th suit following with a rebid of that suit shows a GF. Just bid 2♦ here.

[skjaeran]

I play 3♦ here as 5-5 GF. Then again, I play a non-standard convention which applies here; the xyz-convention.

2♣ is a puppet to 2♦; to play or initiating an invite.
2NT is a puppet to 3♣; to play or slammish with 4♥5+♣.
All jumps are natural GFs, showing 5-5 or a very good suit (rebid).
2♦ is a conventional GF for all hands not fitting 2NT or a jump (3-level or to game).

2♦....WTP?

[aguahombre]

2D (GF)...then 3D to describe. The 5-5 Jumps are workable, unless you want a bid to describe XX QXXX KQJXXX X or the like. Some are content to just rebid 1NT with that, or to respond 1D the first time.

I thought this was the normal approach to 4th suit auctions.

This was Q1 in last week's Tannah Hirsch (Goren Bridge) Weekly Bridge Quiz that I happened to read while in a waiting room. The answer given:

Two diamonds would be fourth-suit forcing, not necessarily promising a suit, and might cost a round of bidding. A jump to three diamonds describes your hand much better.

With a pickup partner who agreed to play a generic 2/1 or SAYC, I would have assumed a jump in the fourth suit would be invitational. Whether that is best in theory is a different matter, I'm just talking about what I would guess to be standard.

[mike777]

IT seems fine to jump to 3d playing xyz to show this hand type.

That means you can play 2d(artificial game force) and then 3d to show 5-4.

Playing with a pickup partner if she jumps to 3d I am never going to risk passing.
1c=1h=1s=3d

Playing walsh style and without xyz, 1c=1h=1s=3d is an auction one needs to discuss, is it strong, invite or weak with long d?

[Fluffy]

Even not playing XYZ I thought 3♦ GF was the most comon tratment, but seems I am disapointed again

[gnasher]

In BWS 3♦ is a splinter if 2♦ would be game-forcing, but natural and game-foricng if 2♦ would be a one-round force. That's where democracy gets you.

[skjaeran]

I know about people playing 2♦ (FSF) as GF who use 3♦ as 55 inv, 55 GF and splinter. 55 GF is the default meaning without discussion here.

[Cascade]

I have no idea what is standard but we play 5/5 GF.

Further invitational hands have to muddle through the best that they can as bidding fourth suit and rebidding it is not natural for us.

But, I'm glad you mentioned Splinter first ( so you can take the heat instead of me).
2D! = a forcing bid.
3D-jump! = a jump over a forcing bid which is the general definition of a splinter (for the last bid suit--Sp in this case ).

[rd6789]

I would play 3D = splinter, say Axxx/AKxxx/x/Kxx - so 2D here

Me too. For the same reasons I can't bid 4NT as natural and invitational as it would look like a RKCB in ♠.
