JJ On The River On Not Such a Great Board

[toss]

Villain is loose preflop and pretty aggr. postflop. Suprisingly he has a low went to showdown percentage. I'm not using numbers since this is only over like 50 hands. I do know he is loose preflop and aggro postflop though. I have a tight nitty table image.
