after 1NT opening and a 2♣ response, a 2♦ rebid is weak and a 2NT rebid is strong, both showing no 4-card major. (OR VICE VERSA)

anyone plays like that?

A Danish top player whom I played with a few times liked to play that. I have no idea what the rationale behind it is.

Might function as a psychic control, if one ever likes to open 1nt frivolously.

Or play 1NT as natural or a weak 2 in clubs, as a friend of mine once did

I quite like 2NT as natural or a 3♣ opening - that's the proper way of doing it.

If you look up Goren from the 1950s, I'm pretty sure that's what's in there.

Playing this way has the advantage of slightly less complicated sequences, but modern bridge players have no problem with just this tad bit extra memory load. It also helps if LHO comes in, but that's rather unlikely given they've already passed once.

I don't think that Goren ever advocated this method.

I know some play that way after a wider ranging balancing NT (some play 2nt is any max, others play a max with no 4M and any 4M responds 2M).

Perhaps not, but as I recall it, Sam Stayman did (it was part of the original definition of the convention).

[Siegmund]

Some of Ron Klinger's older books advocate "Extended Stayman" over a 4-HCP range which uses 2D and 2NT for 15-16 and 17-18 respectively - and similarly use some 3-level jumps to show maximums with 4-card majors. It requires 2C to promise invitational values rather than include any garbage hands at all -- and this latter objection is why I've never seen anyone but beginners use it in a real live game.

Quite sure that 2C with a weak 3-suiter planning to pass any response had already become common by the 50s, and Goren didn't ever advocate a 2NT bid. I think Stayman's "Do you play Stayman?" included the weak 3-suiter too. Whether he used 2NT in the 1930s, I can't say.
