With 16+ points and 3 ♥s, South will insist on a ♥ game at a minimum. But there is no need to start making jump bids, she starts with a simple 2♦ bid.
North also refrains from a jump, and rebids 2♥ to show the 6-card suit.
South now says 3♥ to set the trump suit.
At this point North reveals some slam interest, making a control-showing bid of 4♣.
South continues the process, and bids 4♦, showing the ♦A.
North has heard enough. He bids 4NT, and when South admits to two Aces he bids the slam.
