bottom pair in blind defense

[rzk]

villain is roughly 48/19/1.5/39 att to steal 40

he's otb, i have 86o in bb, suits don't matter in this hand.

i call his steal raise, flop is 8KQ. i c/r, he calls.

turn is a K, i bet he calls.

river is a brick, i c/c.

i think all my decisions are questionable here.

on the flop, i didn't want to fold but thought if i c/c i'd probably have to fold to his turn continuation bet if an overcard falls. also he can take a free card with a draw. c/r'ing and leading out takes away from him these opportunities. however, my hand might be too weak for this sort of thing.

on the turn, i follow through on my plan hoping he's drawing to a straight or has a lower pp.

on the river, i thought he's aggressive enough for inducing a bluff from busted draws to be slightly profitable (even though he might not bet something like AJ).

what would you do in this hand? if you c/c the flop, what do you do next?
