UTG folds, <font color="#cc0000">Hero raises to $8</font>, <font color="#cc0000">CO raises to $24</font>, 3 folds, Hero calls.

Flop: 7[img]/images/graemlins/diamond.gif[/img] 9[img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/heart.gif[/img] ($51, 2 players)
Hero checks, <font color="#cc0000">CO bets $86</font>, Hero has no idea what the overbet means.

I don't have history or stats with the player so I just have to go with what I do know and I know nothing so, what's my line and what do you put this seemingly random opponent on? So far I've showed down only good hands in the table, i'm not quite sure which one of them she has seen.

That is weird but fold it. Almost every pocket pair above 6s has you beat or is 88. Probably a scared big PP though.
