These are always tricky because if you lead out you'll often get raised by Ax hands you're ahead of. And it's tough to commit SO many chips with just a little overpair. But I think if you check you have to do so with some plan in mind. Check-raise, check-call lead the turn, etc.

Obviously the big question here is what does his little 1/4 pot bet mean? Big pair or weak continuation bet? Against two opponents I'd think an overpair (even AA) would bet more than 1/4 the pot given there's already 3 to a straight on the board. So I think he's a little weak. But I'm still hesitant to check-raise here given it would pretty much pot commit me.

I think I'd call with the intention of leading out on any non-threatening (meaning A/K maybe Q) turn card. Even if he has a bigger overpair you've got some great semi-bluff cards in a 3, 6, or 8 and obviously a 9 gives you most likely the best hand. So you might even get him to fold a better hand if the right card comes.
