You have just a little extra so you bid 3♣ to show a singleton. Partner says 3♥ and it is your bid again. Partner's bid means he has first round ♥ control, obviously the ♥A. But it also denies holding the ♦A since control bids are made up-the-line. You show your lack of a Minor suit Ace by returning to 3♠. Partner signs off at game. You could equally have just bid 4♠ yourself.  Deal 4
