What you refer to as Jacoby 2NT in ACBL (and mostly online) is called Stenberg in Scandinavia. Alvar Stenberg of Sweden invented this convention prior to Jacoby. Originally it showed a GF raise, these days it's often played as inv+. There's a lot of response schemes out there. Nobody over here play the standard Jacoby response scheme (maybe an exception for people who've been taught online by americans).

I play 2NT as a GF raise with my partner. Our responses are:
3= any minimum, 11-13(bad 14) =>3=relay
3= 14+, any singleton => 3=relay
3= bal 15-17 (6322/5422) =>3=relay
3= (13)14-16 any void =>3NT=relay
3NT= 18-19NT
4m= 17+, void
4M= 17+, void OM

(This scheme also works if 2NT is inv+, responder rebids 3M over 3 to sign off.)

I love it..much better than the awful "SA" responses to J2NT. Is there a web site explaining further continuations after the relays ? I looked but couldn't find exactly what I was looking for and found some different responses to Stenberg as well.

TY .. neilkaz ..

You won't find this variant on any website I know of.
But I'll fill you in how I play it:

1M-2NT
3-3 (relay)
3=11-12NT
3=any singleton =>3NT=relay, 4=, 4=, 4M=OM
3NT=13-14NT
4m=void
4M=void OM

1M-2NT
3-3 (relay)
3=single
3NT=single
4m=lowest cue, single OM
4M=now side suit cue, single OM

1M-2NT
3-3 (relay)
4=6322 =>4 relays for 3c up the line
4m=4c (5422)
4M=4cOM (5422)
Kind regards,
Harald

South should pass with
♠ T9752 ♥ A ♦ AQT98 ♣ J2
IMO.

This hand is light on HCP and has the flaws of Jx and a stiff A.

Then the bidding is easy:
p-1H;1S-2S;Invite-4S


If South does open that Jreck +and+ "standard" J2N is on:
1S-2N!4S since
1= South has a dead minimum on this auction.
2= "standard" J2N includes Fast Arrival.

Playing Slow Arrival, South would rebid 3S, "I have nothing extra to say" instead of leaping to game and then N would bid 4S.

Under no circumstances is S's subminimum opening worth a positive response to any form of J2N.

Let's assume South opens 1, then:

2NT (Invite or better 4+)
3 (Minimum)
4 (GLP)
Two wrongs don't make a right, but three lefts do!
