We addressed 1NT (12-14 balanced) in earlier lessons because:
Bids of one of a suit and responses to such bids are unlimited in strength and rather unspecific in shape so the first bid needs careful thought. It’s all about handling whatever partner may throw at us without misleading him too badly. This also a key reason why we open “1NT” if possible so we never mislead partner by bidding it later with a mere 12-14.
We looked at several hands which presented debatable opening bids. The first step with all hands was to count HCP and see if the hand was eligible to open 1NT, rebid 1NT or neither. The synopsis is what should form in your mind when you pick up the hand. And should the synopsis be “balanced with 12-14” think no further: bid “1NT” (but in tempo).
