When to show caution on a paired board?

[Vinland]

I don't have a hand history to show...I'll try to explain it quickly...
I was playing a full ring $0.01-$0.02 cash game and was in a limped pot with two others. Villains often limped into pots but folded to cbets/probe bets when they had nothing. So their range is pretty big. On the flop the OOP player led out and I had nice implied odds on the flop to hit my open ender and so I took it.
The player behind me just called. The turn came out and completed my straight. The flop contained two J's and my straight was probably nicely concealed.
The OOP player led out again and I called as did the player behind me.
I put the OOP player on basically nothing or 2 pair. I felt like he opened the pot to start and was just continuing his aggression. The player behind me I was praying he held a J and hit his set or was drawing to the nut straight (mine was best at the time but if the right card came out he could have the better straight).
The river was nothing. OOP player checks, I bet out 1/2 pot hoping to get raised, I did by the player behind (he shoved) and the OOP folded.

The player behind had slowplayed a full house that he hit on the flop. It was a cooler, and an unlikely holding, but should I have been wary of it? Or do I have to just assume I am ahead? There were 13x Jack combos he could have in his hand and only 4 of them spelled doom (JJ gives quads, and 3 other JX combos gives a FH).
That leaves 9 where he is crushed and I rake in the pot.

How are we to approach a hand when the board is paired? I doubt he would have bet any different unless he had the lowest of the Jack combos (J2 - J5). Could I really fold in a micro stakes game??

When to show caution on a paired board? Always Although it sounds obvious, it's always a good reminder that paired boards bring quads and full houses into play, so if you have a straight or flush in those situations, you obviously can't play them as confidently if the board was not paired. If an opponent is very aggressive or shoves, that's usually a red flag - sometimes you might get lucky and he only has trips, but even most bad players get a little cautious when the board pairs, so if they are being aggressive, we have to ask ourselves why and trips is usually the best case reason and a full house or better worst case.

As for the specifics of that hand. It's hard to say without knowing your villain or the specific cards. Having a Jack with an Ace, King, Queen, or Ten is not that uncommon for players to have and if that's what gave him his full house, then I think you can get away from it easier - especially if the villain is tight. If the villain is loose or he used a card 9 or lower with the Jack to get a full house, that's going to be tougher to lay down as you'll be apt to think he has trips more often.

QFT, along with the rest of your post. It's all about knowing your opponent.

For instance, I'm holding AA from mid position, and TAG BTN calls. I'm not worried when the flop hits 424, because it's completely out of his range unless he's holding pockets. If so, I'd be paying him off anyway, so I don't worry too much about it.

The ones that reall worry me are paired 7-J, because it seems to hit so many loose ranges really hard. Paired Q-A pretty much slows down the action becase it hits everyone's range.

I guess it would help if I mentioned the flop
It was KJJ rainbow. The turn was a 9 which gave me my straight (held QT).

Opponent held KJ in his hand. and he doubled up...

I think you would have been better to bet the turn, if he raises you at least you've got half an idea where you stand, also if he does have trips and no boat you're giving him a free river by checking.

[Vinland]

Yeah I wish I had the history.
There was betting on every street, no checks.
The player who opened the pot kept betting the flop and turn and I along with the other opponent would call. He checked river, I led out for a 1/2 pot bet and the opponent after me shoved with his boat. That turn card was the worse possible...

this. it all depends on your read of the situation. that being said, protect you hand and be aware of traps.
