villain is 28/22 after 229 hands / 87% fold to 3 bet pf / att to steal 37% / 1.6 agg / 52% c bet flop

i decided to 3 bet this hand cause villain seems like hes trying to steal a lot and folding to 3 bet a lot. plus, he seems like hes not very aggro post flop and not c betting lots of flop. i 3 bet to take it down pre flop.

when i pick up a gutshot on the turn, should i continu betting? since i picked up some equity and i have no showdown value, i feel like i should probably continu betting to make him fold TT 99

on the river, would it be a good spot to bluff as played? i have no showdown value and its i dont think villain as that much flush in his range after checking river
