Pre-flop: (6 players) Hero is UTG with A[img]/images/graemlins/spade.gif[/img] K[img]/images/graemlins/diamond.gif[/img]
<font color="#cc0000">Hero raises to $8</font>, 2 folds, <font color="#cc0000">Button raises to $22</font>, 2 folds, Hero calls.

Hero checks, Button checks.

Turn: K[img]/images/graemlins/heart.gif[/img] ($47, 2 players)
Hero checks, <font color="#cc0000">Button bets $30</font>, Hero calls.

Hero checks, <font color="#cc0000">Button bets $85</font>, Hero calls.

How's this? Villain is 19.6/12.4/4.6 over 200 hands. His cold call freq pf is really small so I think his reraising range is far wider than QQ+/AK. Is this line ok or should I a) find a fold, b) reraise at some point?

4-bet pre-flop if his reraising range is wide. You're putting your self in difficult situation.
