18-19 HCPs balanced hand.

No 5 card suits or singletons. 4333 or 4432 distributions only. Bid replaces opening a hand too strong for 1NT in a short minor suit. With a 5 card suit open 1 of the suit and rebid 2NT / 3NT to show strength. This way you will be playing a 1 level contract in your 5 card suit when partner has a bust. After a minor suit opening and any suit response at the 1 level from partner, a 2NT rebid would indicate that the minor suit was 5 cards in length.
