Live 2/5 hand: J2o in the BB

[sweetjazz]

Just want to check that this is standard. It's a live 2/5 game where the table is of course too loose and a bit too aggressive on the early streets (preflop and flop) but too passive on the turn and river.

An EP player limps, a LP player limps, SB completes, and I check my option with Jh 2s. EP is a young loose aggressive player. I suspected at the time he was capable of firing multiple barrels with air though he had not been caught doing so to this point (but later he did 3-barrel no pair against a calling station and got looked up by top pair), but he's certainly not reckless. So he generally seems pretty good except he's too loose and a bit too easily trapped.

Flop is Jd 8c 6c and the action goes: SB checks, I check, EP bets $20, LP folds, SB folds, I fold.

(1) Is this a pretty reasonable default action, especially given that I don't have control over the villain in the hand?

(2) If you don't check this flop intending to fold to most bets, what's your plan for the hand?
