Small Stakes No-Limit Hold'em

I was wondering if I can get any input on a hand I played recently:

I raised to $4 on the button with 8h6h after the CO open-limped. He called, and everyone else folded.

I think the CO would have open-raised with 77+ and AT+, so I put him on a lot of suited connectors, small pairs, suited Aces, and Broadway cards. His style was loose-passive (thus the open-limp), and he probably puts me on a wide range.

Flop: 6sTs2h
Pot: $9.50
Stack: $96

I bet $5 and he calls.

Turn: 6sTs2h-(Ah)
Pot: $19.50
Stack: $91

He checked again.

THOUGHTS:

I think if I bet he will fold pairs worse than mine (55-33 and 6x) and call with his flush draws and his pairs of Aces (most of which are spades because he check-folds his bare Ax’s on the flop), and he might even call with his Tens on the turn because my image at the time was pretty aggressive. I think he would check-raise two-pair or better.

QUESTIONS:

Does the fact that he mostly folds hands worse than mine detract from the semi-“bluff” element of the bet?

If I bet the turn, should I bet the river to try to get him to fold a pair of Tens? If I don’t plan on betting the turn, should I just check behind the river as well?

Thanks in advance!
