Forcing to two of the opening suit is almost universal on the British islands. People open too light for f2nt to be playable.

Interesting. As I have already stated on more than 1 occassion, forcing to 2NT was standard in Australia even 20 years ago. It is FAR superior to have responder promise a second bid rather than the crude method of only forcing to 2 opener's suit.

Why not promise a second bid unless opener's rebid is 2NT?

2NT in this situation is normally forcing to game.

2NT is a 15-17 rebid and is a gf.

If you want to play sound 2-level responses in a weak nt 4cH 5cS context you can play kaplan inversion.

It seems to me that 2/1 forcing to 2NT incorporates the worst of both worlds. If you are going to play 2/1 forcing to 2NT, you might as well go whole hog and play it forcing to game.

Well, I've never been a convert to 2/1. Don't like forcing NT and never have.

It is not really playable either since opener will pass the 1NT response with 15-16 points.

But presumably you could play a sound multi/muiderberg style in combination with mandatory 1NT opening on 5M332 in range. Then 1M will be sound unless it is both majors, so 1♠ followed by 2♠ would be showing a sound opener and could be forcing. You still have to find a solution for the 10-12 Flannery hands, though.

It works with a 14-16 NT opener though.

And yes, though it has its drawbacks, a 5M332 opens 1NT when in range. And, yes, I do like (constructive-ish) 2 suited pre-empts. Prefer 2D multi and Polish style 2H, 2S, 2NT (5/5 shapes). I don't worry about 5/4 shapes if they are not 1 level openers. Seems to work OK to me.

Coz a 2NT is not weak NT. A weak NT hand rebids a 2nd 4 card suit if possible or repeats it's suit (including making a 4 card diamond rebid if necessary over 2C) and lets responder make the running.

Neither do I, but I do think that 2/1 FG is better than 2/1 F2NT.

Weak NT does not work with 2/1 as f2NT and a non forcing 1NT response. A non forcing 1NT response includes most 10 counts and the odd downgraded 11. Therefore a balanced opener can afford to pass with up to 13 or a poor 14 comfortable in the knowledge that game was 50/50 at best. However once opener picks up a reasonable 14 count, you want to bid, but cannot for fear that responder was weak. Therefore the opening NT has to start at a reasonable 14 count.

If you're saying you don't like my system - fair enough - it isn't perfect. But neither is Acol, SA, or 2/1 (or Precision or Blue Club or whatever).

Edit, p.s. depending on exactly what your 1 of a suit openers show, a weak NT may well be opening 1C a lot (or all) of the time. In which case the argument about what is forcing or not etc on a weak, balanced opener tends to go away.

It's not that I don't like your system; I didn't know what it was. I had gathered from an earlier post that you don't play 2/1 F 2NT. My mistake.

PS As open strong NT, I am wondering what a 2NT rebid after 2/1 shows.

It depends on who I am playing with!

Assuming I'm playing 2/1 as F2NT, then the 2NT rebid works FAR better as a strong (17+) bid. If you gobble up the whole 2 level to show a weak NT, when responder isn't going to drop the bidding below that level anyway, then you make it bad for the 17+ flat hand that now presumably has to rebid 3NT (eugh). Further, when responder was planning a reverse, they are now forced to the 3 level to show it.

Really it is far more like playing 2/1GF (but not quite) without the forcing NT response than it is to Acol or Standard.
