UTG calls t30, <font color="#666666">4 folds</font>, CO calls t30, <font color="#CC3333">Hero raises to t125</font>, <font color="#666666">1 fold</font>, BB calls t95, <font color="#CC3333">UTG raises to t220</font>, CO folds, Hero ?

what my line here the limp utg then raise is very suspicious...no reads as early on.
