Blind Steal vs. a calling station

[Moneyline]

10/20 online 4 handed. BB is a calling station

Folded to me in SB, I raise 6 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/heart.gif[/img]. BB calls.

Flop: K [img]/images/graemlins/club.gif[/img] 4 [img]/images/graemlins/club.gif[/img] 2 [img]/images/graemlins/spade.gif[/img](h/u, 4SBs)

I bet, BB calls.

Turn: 8 [img]/images/graemlins/diamond.gif[/img]

I bet, BB calls.

River: J [img]/images/graemlins/heart.gif[/img]

I check with the intention of folding to a bet.

And for an added bonus question: Would you raise 65 in this spot preflop if it wasn't suited?
