TPGK faces aggro

[Fadook]

Recently replaced a shorthanded table with FR in my multiabling routine, so I'm a little rusty.

Most of the hands I've played with CO have been shorthanded, where he's always seeed like a pretty decent player. Some occasionally misplaced aggession, but nothing too crazy. BTN is really loose and stupid.

.5/1 8-handed
Hero is UTG with K[img]/images/graemlins/spade.gif[/img] Q[img]/images/graemlins/heart.gif[/img]

Preflop: Hero raises, 3 folds, CO raises, BTN calls, 2 folds.

Flop: (10.5 SB) 8[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/diamond.gif[/img] 3[img]/images/graemlins/spade.gif[/img] (3 players)
Hero checks, CO bets, BTN calls, Hero calls.

Turn (6.75 BB) 5[img]/images/graemlins/heart.gif[/img] (3 players)
Hero ?

Is this an obvious get to showdown as cheaply as possible?
