Pre-flop: (6 players) Hero is Button with Q[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/diamond.gif[/img]
3 folds, <font color="#cc0000">Hero raises</font>, SB folds, BB calls.

Flop: 5[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/diamond.gif[/img] Q[img]/images/graemlins/spade.gif[/img] (4.5SB, 2 players)
BB checks, <font color="#cc0000">Hero bets</font>, BB calls.

Turn: 5[img]/images/graemlins/spade.gif[/img] (3.25BB, 2 players)
BB checks, <font color="#cc0000">Hero bets</font>, <font color="#cc0000">BB raises</font>, <font color="green">Hero?</font>

What line on the turn would you take if:

a) BB is LPP - Hero? (this one is a bit rhetorical!)
b) BB is TAG - Hero?
c) BB is LAGtard - Hero?

Also I was curious to the hand below, is this standard even against an unknown?
