You are playing 12-14 1NT openers, so bidding 1NT now would show 15-17

Another example where you have a good opening with a good 6 card minor suit.   My rebid was 2 ♣, and this hand is too good for that.   Again a 3 ♣ rebid is best.   A 1NT rebid, showing 15-17, may work too here, but East had ♠ AV87 ♥ 762 ♦ 876 ♣ H32 so your 3 ♣ makes it easier for East to bid 3NT.
