Monster on the river, but is it big enoush?

[ReDeYES88]

Villan was playing fast and loose, limping with a ton of hands. Trap at times with made hands, probe other times when missed. I think he has a good piece, but how big?

Preflop I don't think there's a need to raise OOP with the stacks the size they are. He's flat called a good share of raises PF with a wide range, and I don't think there's a need to start with a big pot on the flop. Would you act differently?
