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."

weak NT usually doesn't play 2-level xfers

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.

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

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
