Split or suck - call down?

[Roy6]

2nd orbit, table seems tightish, thatswhy no PF 3-bet, maybe a mistake though.

On the turn:
-A split is very likely, I don't know 2 or 3-way
-Anybody with a straight + /images/graemlins/spade.gif is freerolling against me
-I raised the turn, because I thought it might be likely that PFR slowplayed a set on the flop.
Or maybe he can fold 7 /images/graemlins/spade.gif 7 /images/graemlins/diamond.gif, that would be nice

-When it's 2 back to me I don't if it's OK to continue...
I thought I'll fold a river if it's a spade.

-The river: although it's unlikely that PFR had the set, given he 3-bet turn, how do you react
-PFR raises, SB calls ... guess I call
-PFR raises, SB 3-bets ... guess lay down?

I think you should fold. But its such a huge pot I would kill myself if I could have won... But its so unlikely imo, especially with that river card.
edit. didnt see that it was two back to you on the turn. I think you can fold there.

Fold with two back to you on the turn. Spliting at best.
