I really enjoyed 14-16 NT when I played it (in a polish-style club system, some years ago), and felt it was a winner when it went against the 15-17 field. Oddly, the reason I quit playing it was when I started playing a souped-up form of checkback stayman, and decided I was quite happy to open all my 11-14s with 1C.

The semiforcing notrump issue does seem like a good reason for the 14-16 NT, since that's a sequence where opener's balanced 14 is a real problem hand, whereas comparing 1N vs 1C-1M-1N ont he other hands is more or less a wash.

Now if we can solve the rebid problem of the 14-15 with 4-5-2-2

The INV+ relay method solves this problem easily. After 1♥ - 1♠, 2♣ = 4+ spades; 1NT = min without 4 spades; others = max without 4 spades. After 2♣, if Responder has a GF hand they can relay with 2♦, and if not they make a natural bid after which Opener can drive to game with 14-15.

[whereagles]

You don't really NEED it to be forcing, unless you want to use 1M-3NT for some sort of raise or do some other high-tech gadgetry which requires a 100% forcing 1NT.

[mtvesuvius]

Just bid 2♣ on those hands

And if you're feeling Rexfordian, you can bid 2♣ over 1♠ with your 5-4-4-0s.

I like 14-16 hcp for 1NT openings also.

Another reason for playing 1NT rebid for balanced hands after opening 1♣ as 17-19 is to keep out the lead directing overcalls at the 1-level.
