Played someone recently whose 1NT range was 11-17. I wish I'd had time to find out what the follow-ups were. And the sequences they were gaining with whatever they used a 1NT rebid for.

When we played 11-16, we played a 17-19 1N rebid which got the occasional gain when other people were playing 2N.

And how well did it work after that wide 1NT opening?

Seems like responder can pass with ca 0-9, and force to game with 14+.

So, for example,
1NT-2NT = 10-13?
1NT-2C-2H-3H = 10-13?

Or did your system distinguish between "weak" invites (10-11) and "strong" invites (12-13)?
