I think you overvalued your pair OTT.You have better hands to continue, you don't have to call this.OTR with AJ you don't have good blockers.Again you don't need to call this you have better hands.

BB's line is pretty strong, and heavily underbluffed on average, specially on very dynamic boards, unless he is a spazzy fish. You hold a bluffcatcher so I'd fold vs the turn check/raise. Same applies on the river, with the addition of facing an overbet.

I also think that checking back the turn is way better than reopening the betting and increasing the size of the pot, there are many bad river cards, and most donkers like to donk...so you could face a check-call turn + donk river on a bad river card and if you call you will end up putting 3 bets with a medium top pair on a very drawy board (and it's UTG vs BB). Checking allows him to bluff the river with his missed clubs/air, and bluffcatching vs a medium sized bet on a river blank would probably be +EV.
