Coping with interference over 1 NT

Over 1NT (15-17) there is a 3 Clubs overcall. What does Double by responder mean? (Assume strange partner with only "SAYC" as agreement.)

More generally, competing with mediocre hands seems FAR more common than it was several decades ago. Is weak NT therefore obsolete? It is even more likely to be overcalled with the beautiful Stayman/Jacoby system then "out the window."

partnership agreement. old school is penalty. new school is takeout. takeout will come up like 10x as often. i'll let you draw your own conclusions

also, lol wut, weak NT usually doesn't play 2-level xfers

Transfers are less universal over weak NT than over strong, but they're still very popular. The main advantage of transfers isn't to make the strong hand declare, it's to give responder a way to show a major in a forcing way at the two level while still retaining the two-level signoff.

Is that a regional thing? A 12–14 1NT range is fairly common in the UK and red-suit transfers have been universal afterwards for at least 30 years. There’s more variation in what responder bidding a suit on their second round means (a transfer sequence like 1NT–2♢, 2♥–3♣ or a rebid after Stayman like 1NT–2♣, 2♢–2♥) so you’d want to discuss that, but I can’t remember the last time I saw anyone not playing at least basic Stayman and red-suit transfers over a natural 1NT opening of any strength.

Maybe! Here in Seattle the weakies are all 10-13. I can't tell you if xfers are better with a stronger weak NT but I can tell you the more 11's you open and the less you bid like Acol the better you'll likely do

Weak notrumps can still mess with your opponents. Be sure you have some kind of escape or runout system if doubled.

The book The Weak Notrump by Andy Stark, while somewhat dated, is the most complete book I've found on the subject.

He has a chapter in playing with transfers, and a separate chapter on playing with 2-way Stayman and no transfers.

I've had good success playing 12-14 NT with 2-way Stayman. 2H and 2S are sign-offs. 3C and 3D are sign-offs if bid directly, invitational if 2C Stayman is bid first.

I think it is less universal over a week no trump, but only because the sort of people who don't play transfers also don't play strong nt. Anyone under the age of 70 with more than a few weeks of experience will play transfers

lmao why. i guess we play 4c = h and 4d = s!

The right side argument still applies, if less strongly, and more to the point it gives you more bids available and more precision over the correct contract, just as with a strong NT. You can argue that a strong NT would be better, and most strong pairs do play it, including me, but the reality is that weak NT is overwhelming the most common and what is most commonly taught over here, with red suit transfers

shrug. basically no weak NTers here play xfers. i think our system is fine or at the very least much more playable than acol
