Party 2/4 - when to slow down?

[Wad]

I came across this hand in my second orbit this morning, no reads on any players yet.

Party Poker 2/4 (9 handed)
Wad has A[img]/images/graemlins/diamond.gif[/img], A[img]/images/graemlins/club.gif[/img] and is EP1

Wad raises, MP2 calls, Button calls, SB 3-bets, BB calls, Wad caps, MP2 calls, Button calls, SB calls, BB calls

Flop(20 SB): 4[img]/images/graemlins/club.gif[/img], 5[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/club.gif[/img]

SB bets, BB calls, Wad raises, MP2 folds, Button folds, SB calls, BB calls

Turn(13 BB): 2[img]/images/graemlins/spade.gif[/img]

SB bets, BB folds, Wad raises, SB 3-bets

Who caps here?
How far do you go on the river if a non-club hits?

I'd cap the turn. Hard to believe SB has a preflop 3-betting hand that has two clubs given that you have the Ace. A 3-bet from K [img]/images/graemlins/club.gif[/img] Q [img]/images/graemlins/club.gif[/img] or Q [img]/images/graemlins/club.gif[/img] J [img]/images/graemlins/club.gif[/img]? Seems unlikely. He's got KK, QQ, JJ with a club or AK and is hoping to scare you but drawing near dead, I think.
