Opener must Rebid a suit

Here is your hand:

♠AJ
♥KQJ865
♦Q62
♣A9

Playing matchpoints and you are vulnerable. The Opponents are silent during the auction.

You are Dealer and open the bidding 1♥. Partner responds 1♠. What is your call?

How about 3♥?

This shows about 16 to 18 HCP and a GOOD six card suit.

If you bid 2♥ you only showed about 13 to 15 HCP. Your hand is much stronger than that.
