All's in the title... What do you play over (3X)-3NT?

[helene_t]

Two under transfers e.g. 4c-> hearts to give p room to superaccept without forcing to the 3level.

5-level?
But sounds simple and effective.

[helene_t]

It would be nice also to have a way to show specific twosuiters with and without slam interest. I haven't given it much thought. Maybe Phil King has

[the hog]

4C asks on what 3NT was based - a long running suit or a strong bal hand
Bid the suit or bid 4 theirs or 4NT strong bal
4D - t/f to H
4H - t/f to S

[whereagles]

With a former partner I played:

(3m) 3NT (pass) ??

4♣ = 55 majors
4♦/♥ = transfer
4♠ = 4441 (sing m) slammish
4NT = quant

(3M) 3NT (pass) ??

4♣/4♦/♥ = transfer. Transfers into opening major = michaels style 2-suiter
4♠ = 4441 (sing m) slammish
4NT = quant

(The 4♠ bid is somewhat dangerous if pard forgets it lol.)

This assumed 3NT was made on a balanced or semibalanced hand. If the 3NT overcall can be made on running suits + singletons, Ron's scheme is perhaps better.

[PhilKing]

This is what I knocked up for Townsend/Sandqvist.

Over (3C)-3NT:
4C Enquiry (mild try or slam force)
4D Puppet to 4H (then 4S/5D to play, 4NT ace ask)
4H/S/5D Invitational
4NT Strong invitation (accept with 17)

After (3C)-3N-4C:
4D 18+ (forcing to 4NT)
4H/S/NT 15-17
5D Nat

Over (3D)-3NT:
4C Enquiry (mild try or slam force)
4D Puppet to 4H (then 4S/5C to play, 4NT ace ask)
4H/S/5C Invitational
4NT Strong invitation (accept with 17)

After (3D)-3N-4C:
4D 18+ (forcing to 4NT)
4H/S/NT 15-17
5C/D Nat

Over (3H)-3NT:
4C Enquiry (mild try or slam force)
4D Puppet to 4S (then 4S/5m/¨ to play, 4NT ace ask)
Can “break” to 4H to show a monster
4H 2-suiter, inv+
4S/5m Invitational
4NT Strong invitation (accept with 17)

After (3H)-3N-4C:
4D 18+ (forcing to 4NT)
4S/NT 15-17
4H some sort of bridge bid
5m Nat

Over (3S)-3NT:
Mostly same

4S 2-suiter
4C then 4S bridge bid - maybe 3 suited

[kenrexford]

I'm just thinking here.

4C as one or both majors. Partner bids 4D if he prefers spades.
4D asking type. 4NT strong balanced. 4M flags long minor.
4M natural but ongoing (4C option is weaker).
4M if cue both minors.

[Kungsgeten]

Our 3NT system is:

4♣ = Baron (bid 4+ suits down up, if a fit is found respond key cards at five level, 4NT tells no more suits)
4♦ = Puppet to 4♥
4♥/♠ = 5+ suit, forcing (4NT denies slam interest, 5-level shows key cards)
4NT = Quantitative
5♣/♦ = Non-forcing slam try

After the puppet to 4♥:
pass/4♠/5m = To play
4NT = Ace asking

We have not defined what a cue bid would mean.

Quick question. As 3NT can be on a long running suit or a strong balanced hand, how does your method allow you to distinguish the difference?
I bid 3NT over 3C on
K
AKQJxxx
AX
Axx
and many similar hands.

[whereagles]

only 3NT on that? I'd be giving a straight 6♥ serious consideration

Our methods does not allow us to distinguish the difference. It is probably better to play something like what PhilKing suggests, instead of Baron. Out methods came from a system over a situation where partner has shown a really big NT-hand, like 2♣ (strong)-2♦ (waiting); 3NT (25-27).

[awm]

4♣ = asking strength/type
4♦ = some GF two-suiter
4M = long suit, to play

After 4♣:
... 4♦ = min (16-18)
... 4♥ = better (19-21)
... 4♠ = very strong (22+)
... 4N = running suit and stoppers

What we play might not be the best, but it gives us enough tools for a decent continuation imo. Since it's quite a rare auction, we prefer something simple:
4♣ = baron (asks to bid 4 card suits up the line)
4♦ = transfer ♥ (to ♣ if opps suit is ♥)
4♥ = transfer ♠ (to ♣ if opps suit is ♠)
4♠ = transfer ♦ (to ♣ if opps suit is ♦)
