Interesting slam hand.

P by East and then South has to decide between 1♠ probably best as not strong enough for an Acol 2♣ , though Benji players will be able to bid 2♣ (2♦ is the game forcing opening).

West can make life difficult with 3♥, especially as NV.

North has dificult decision. 3♠ ,3NT or double.

3N is risky, if South is minimum, but shows the stop. Over this South might bid 6♠ or 5♥ Exclusion Keycard Blackwoood  a useful slam tool, asing for Blackwood RKCB responses, ignoring those in suit bid. This is used when you need to know keycards outside of the void.

Over 5♥  North bids 5♠ showing 1 or 4 Keycards outside of ♥ s. 

Before Souths bid East could be disruptive by bidding 4 or 5 ♥ s. 5 stops Blackwood.

South then raises to 6♠ .

Some people NV to V may open with a disruptive 2♥  (needs to be alerted as 5+ and weak - or Lucas 5+♥ s and a minor weak)
