Live 2/5 hand: J2o in the BB

1) this is fine. There are a good amount of players in this pot and it's unlikely he's potting it with 89 or somesuch. His range is mostly strong draws and Jx+, and as you intimated we will have no way of discerning one from the other on the big streets putting us in tough spots oop.

2) I do check this flop intending to fold to most bets. If it is ckd around to button who stabs 2/3 pot I might call, assuming I can rely on him to give up his pure bluffs with some predictability.

in a limped pot with this many draws vs unknowns I'll tend to fire out a 2/3 bet and hope to get peeled by T8, T9, 89, 78, 67, 56, or 45 (or any other middling pp that has some gutshot to go with it).

If i get peeled and am out of position I'll tend to fire a half pot bet on the turn and check the river.

this is of course exploitable by aggro players, but only if we're both deep enough for it to matter. Since you have an aggro in the pot with you, and alternate plan could be check/call flop, bet turn, check river - again stack and card dependant.
