call all in with 2 pr on flushy river?

I'm new at this table, but villain seems LAG, and had pushed a river earlier but the opp folded. I've been tight so far, and recently stacked a shorty with an overpair all in on the flop.

I know I could bet the flop, but figured I'd induce a bluff. then on the river I value/block bet (thoughts on bet size?) but still called the all in.

I think he should've put me on a good hand, so was it a bad call?

yea u have to go broke on river, but i would bet flop. you dont need to try and induce bluffs when alot of worse hands call you there anyway
