Flopped a set, turn has a flush, river gives me the boat.

4-tabling. No major reads on villian except that he has roughly 25% VP$IP based solely off of GT+

Flop: (7 SB) A[img]/images/graemlins/diamond.gif[/img], 8[img]/images/graemlins/club.gif[/img], 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(7 players)</font>

Is there any way I could've protected my hand on the flop? My thinking when getting a set is ram and jam.

Turn: (5.50 BB) 9[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">Hero bets</font>, BB calls, <font color="#CC3333">MP1 raises</font>, MP2 calls, Hero calls, BB calls.

Didn't want to see a club. The raise put me in calldown mode.

River: (13.50 BB) A[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
<font color="#CC3333">Hero bets</font>, BB folds, <font color="#CC3333">MP1 raises</font>, MP2 folds, Hero ???

Manna from heaven! A boat. But I got raised again, could he have a higher boat? What should I do?

Final Pot: 17.50 BB
