Commerce 40-80 hand

[Dazarath]

I was at Commerce on saturday, and I decided to take a shot at the 40 game, since the line was much shorter than the 20 (my normal game).

LMP just sat down maybe an orbit ago. He seems loose-passive from what I've seen. Definitely passive, but it's possible that half of his hands so far were worth limping and I'm drawing an incorrect "loose" conclusion from a small sample size. BB is loose as well. Here's the hand:

Folded to LMP who limps. Hero raises KJo to isolate. BB calls and LMP calls.

Flop is Q J x.
BB checks. LMP bets. Hero..?
I decided to raise to shut out BB and check the turn UI. With the pot being only ~3.75 BB, is this just a fold, since I put him on a Q? Or is it worth fighting for?
(BB did end up folding.)

Turn: A
LMP checks. I figured this was a good card for me as it should be a scare card for him. Hero bets. Good? Or should I just stick with my original plan and check behind?
(LMP calls.)

River: K
LMP checks. Hero checks. Should this have been an easy value bet?

Thoughts on all streets appreciated, especially flop.

I think you played it pretty well, though you can probably bet the river.

On the flop, you are getting about 7:1, practically enough to continue even if you know he has a Q. Now if he could ever bet a J, or a draw here, then you really have to continue with the hand. And if you are going to proceed I prefer a raise.

I'd play it the way you did, but I would bet the river. Most opponents will bet out with a T fearing that you'll check behind here.

i don't bet the turn, as no better hands are folding, certainly no ace, and very unlikely a queen.

I do bet the river.

I'm not sure about raise or call on the flop.

All he's done is call? I wouldn't worry about his hand too much and bet the river. Is he passive enough that you don't have ot payoff a c/r?
