Bottom set on flop

[piiop]

Party 100 full.

UTG+1 - $110 - Loose weak
MP1 - $50 - Unknown
CO - $110 - Very loose call station
SB - $55 - Tight, very agg postflop
Me/BB - 100

All those people limp, the rest fold. I check with 5 [img]/images/graemlins/spade.gif[/img]4 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/heart.gif[/img].

Flop (5) : 8 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/heart.gif[/img]4 [img]/images/graemlins/club.gif[/img]

SB bets pot.

SB would bet here with 88xx,77xx, bare 56, 56 w redraws, wrap with or without flush, or bare nfd. He's unlikely to pay off a boat. The other crappy players are unlikely to raise big draws but are likely to pay off.

I do what?
