Bidding over a Pre-empt

Here is your hand:

♠AKQ72
♥A942
♦AJ95
♣-

Playing matchpoints and everyone is vulnerable. Your RHO (Right Hand Opponent) is Dealer and Passes. You decide to open the bidding 1♠. Your LHO bids 3♣. Your Partner bids 3♥. Your RHO Passes again.

First think about what Partner is showing.

What is your call?

I hope everyone drove to a slam on this board. Partner should have a strong hand with long ♥. You have a VERY nice fit with Partner and you have 18 HCP PLUS you have a useful void worth at least 5 points.

It would be nice to know how to bid this properly but that involves cue-bidding and that is pretty complicated. For now a leap to 6♥ gets the partnership to slam easily enough.
