Assume 1nt is 14-16 or 15-17

1nt=(2nt)=?

Do you play stayman, smolen, tfr, system on or anything over this? IF so what?

[gwnn]

is this UNT? you can always use some sort of UVU over this. Whatever you play vs minor preemptive 2NT.

e.g.:

3♣=4♠, 5+♥
3♦=vice versa
3M=invitational (?)
3NT=obvious
4♣=good 4M bid possible slam interest
4♦=55 or better in majors
4M=s/o

Oddly, considering the detail to which some of my systemic agreements delve, in only one partnership have I had a written agreement, which is:

x = balanced, 8+, invites defending, if later bid 3N, shows ♣ stop, denies ♦
3♣ stayman
3♦ transfer, at least invitational
3♥ transfer, at least invitational
3♠ transfer to 3N, promises a ♦ stopper, denies a ♣ stopper
3N to play, both minors stopped

4♣/♦ S.A. Texas (ie what we played absent an overcall), transfer to ♥/♠

The decision to bid 3N, rather than to play for penalty, will depend on extent of defence and relative vulnerability

I guess it is a sign of the relative infrequency of 2N that I do not ever recall, in that partnership, ever having to use this structure. I had to go back to the notes (we haven't played in years).


I discussed this with my current partner and he plays (but had not so far shared this with me, so thx for the post):

double invites penalty
3♣ stayman
3♦/♥ transfer
3♠ puppet to 3N, expressing doubt
3N to play, no doubt

Frankly, I prefer the 1st method, and I will now try to get cp (current partner) to agree

Depends on what 2N shows. Some Hamilton/Cappaleti players use 2N for any big 2-suiter. Some Suction players use it for the rounded suits, others for ♣ or (♦+♥).

First case (minors): 3♣ is Stayman
3♦ is an invitational+ transfer to ♥
3♥ is an invitational+ transfer to ♠
3♠ is a competitive bid in ♠
3N is to play
X is a balanced invitational hand or pure penalty
P is all the rest, including the competitive bid in ♥

Second case (any two suits): X is a balanced invitational+ hand
3♣, ♦, ♥ is an invitational+ transfer
3♠ is a transfer to 3N or 4♣
P includes competitive hands in any suit

Third case (♣+♥): X is a balanced invitational+ hand or pure penalty
3♣ is a transfer to ♦, weak or strong
3♦ is invitational with 5+ ♦
3♥ is a transfer to ♠, weak or strong
3♠ is invitational with 5+ ♠

Fourth case (♣ or Reds): X is a balanced invitational+ hand
3♣, ♦, ♥ is an invitational+ transfer
3♠ is a transfer to 3N or 4♣
