How do you continue on the turn?

CO is a TAG. Not a regular. That's all I remember. Pretty much all I knew about him.
The other player is bad. EDIT: Like 50/15 LP, likes to call, but has at least a pair or a draw when he calls

How would you play the turn? Would there be any difference if the turn card was an offsuit 6?
