1NT is 12-14 so 1C-1D-1NT=should be 15-17, but rest?Especially how to deal with 4441 hands?Any good ideas?

1♥ = extra's, relay (1♠ double negative)
1♠ = 5+♠
1NT = minimum, can be semibalanced (5422, 5431, 4441)
2m = (5)6+m
2♥ = (5)6+♥
It usually works out ok when bidding 1NT on semi balanced hands, but it can be hard when you have 5♥ and some side 4 card suit.
After double negative:
1NT = natural, can be semibalanced (4441, 5422, usually no 5431 -> canapé transfer)
2♣ = any GF (2♦ is waiting bid, other are extremely weak and natural)
2♦/M = canapé transfer
2NT = a non-minimum NT hand
3♣ = canapé transfer

I use a 16+ 1C, however, your 15+ might be able to use the method.
1C-1D-1H*=either natural with hearts(Kokish two way type style) or shows a club suit.
Responder bids a semi auto 1S and opener bids 1NT* with a club hand and any other bid shows hearts and the suit bid.
1C-1D-1S* 1 round force showing 4+ spades. Responder bids 1NT with 0-5HCP,
2C* with 6-7HCP, 2D*=3 card raise, 2H=natural or bids 2S with 4 card support.
1C-1D-1NT* shows 18-20HCP balanced. You might want to 'switch' your NT opening range to a medium 14-16 or 15-17 or you will be 'jumping' to 2NT with 18HCP opposite a known 0-7(8?)HCP. You could also use the 1C-1D-1H as a 18+ relay, however, that causes other problems with the higher rebids.
1C-1D-2C* shows diamonds.
1C-1D-2D* shows 4441 types with 19+ HCP. My testing suggested that the minimum 4441 types should try to stay low opposite a 1D reply.
Changing the range to 19+ also allows very accurate bidding opposite weak hand types.
1C-1D-2H*(Kokish style) strong two hearts or 25+HCP(if 2NT rebid)
I also use a multi 2D opening to show either 6M or 27-28HCP.
1C-1D-2S* minors at least 5-5
1C-1D-2NT=23-24
1C-1D-3C natural force with 5+ clubs
1C-1D-3D natural force with 5+ diamonds
1C-1D-3M= 1 round force with 4(+)M and 6(+) diamonds with a very strong hand.
1C-1D-3NT=to play with long minor and hope for nine tricks.
1C-1D-4C(5503) and 1C-1D-4D(5530)

Robert

1♣ - 1♦ - ?
1♥: minimum 2suiter, higher suit is longer, or 15-17 balanced or GF balanced; 1♠ is semiautomatic, then:
1NT 15-17
2♣ clubs + a major (2♦ relay for the major)
2♦ diamonds + a major (2♥/♠ pass/correct)
2♥ majors
2♠ minors
2NT GF balanced
1♠: minimum 2suiter, lower suit is longer; 1NT is relay (not mandatory), then:
2♣ clubs + a major (2♦ relay for the major)
2♦ diamonds + a major (2♥♠ pass/correct)
2♥ majors
2♠ minors
1NT: transfer to clubs, or 18-20 balanced; here 2♣ is double negative, and opener:
pass minimum 1suiter
2♦ 18-20 balanced
2♥♠ clubs and this suit, non-minimum (otherwise 1♠), one-round force
2NT clubs and diamonds, non-minimum, one-round force
3♣ 18-20 1suiter
positive bids by responder: 2♦ general positive, 2♥♠ 5card suit, 2NT long diamonds, 3♣ INV raise, 3♦+ Splinter: now opener's 3♣ is limit, others are game-forcing;
2♣: transfer to diamonds; here 2♦ double negative, 2♥ general positive, 2♠/3♣ natural, 2NT hearts, 3♦ INV raise, 3♥+ Splinter; further development is as after 1NT, not considering balanced 18-20; after a general positive, 2NT by opener shows a 2suiter: the second suit is the one artificially bid by partner.
2♦: transfer to hearts; here 2♥ double negative, 2♠ general positive, 2NT spades, 3♣♦ natural, 3♥ INV raise, 3♠+ Splinter;
2♥: transfer to spades; here 2♠ double negative, 2NT general positive, 3♣♦♥ natural, 3♠ INV raise, 4♣+ Splinter;
2♠: 3suiter, 18+; 2NT positive relay for the suit under the singleton, 3♣ and more to play (with 15-17, treat as 2suiter)
2NT: 21-23 balanced
3♣♦♥♠: game-forcing 1suiter

Here's the structure that I'm current using
3N game forcing values, 5=4=4=0 shape
3♠ game forcing values, 4=5=4=0 shape
3♥ game forcing values, 5=4=4=0 shape
3♦ game forcing values, any 5440 with a ♦ void
3♣ any solid suit (AKQxxxx or better)
2N game forcing values, any 5440 with a major suit void
2♠ semi-positive, single suited with Spades
2♥ semi-positive, single suited with Hearts
2♦ semi-positive, 5+ Hearts and 4+ Diamonds
2♣ semi-positive, 5+ Hearts and (4+ Clubs or 4 Spades)
1N semi-positive, unbalanced with 5+ Spades
1♠ artificial double negative
1♥ artificial semi-positive (balanced or unbalanced with 4 card major)

Here's a document describing it in some detail (and the rest of the entire system in quite some detail :-):

Maybe Richard plays it differently...

1♣-1♦...
1♥ = extras, try to relay (all others are 15-18)
1♠ = major+minor two suiter, can be (41)44 or 4-5/5-4 either way
1NT = minimum-range balanced
2♣ = both majors, at least 4-4
2♦-2♠ = natural 6+ card suit deny a side 4+ card major
2N = both minors
3♣ = 6+♣ no 4cM
After 1♣-1♦-1♠:
1N = 6+ points, ask for five-card suit
2♣ = 0-5 points, pass/correct for five-card suit
2♦ = ask for major, potentially any strength
2♥/2♠ = 0-5 points and 6-card suit
2N = 0-5 points and 4+/4+ minors
3♣/♦ = 0-5 points and 6-card suit

Thanks for the suggestions, Adam. You're right that bidding 2♥ with 5+ and a minimum was definitely an unpleasant choice in my system.
