You contemplate opening 1NT, but you can't remember whether you play a strong or weak NT, or which range this falls into anyway. So you open 1♥. Your human partner replies with Jacoby.
You decide you like your hand - two doubletons after all - and bid 3NT to show 15-17 points. You receive a 4♣ control bid from your partner.
