<font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to t90</font>, <font color="#666666">1 fold</font>, MP2 calls t90, <font color="#666666">1 fold</font>, Button calls t90, <font color="#666666">2 folds</font>.

Flop: (t315) 6[img]/images/graemlins/club.gif[/img], 8[img]/images/graemlins/club.gif[/img], 3[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets t330</font>, MP2 calls t330, <font color="#CC3333">Button raises to t1340</font>, <font color="#CC3333">Hero ???</font>

the flop looked save. so i figured the most likely cards he could have are an overpair or a set...
should i fold and wait for a better chance to get some chips or should i go for it?
