Should I bluff? (Ignore my location, please)

[TheWorstPlayer]

Villain is TAG. Not really a good player, but somewhat thinking. Takes decent lines and is fairly aggressive, but doesn't really tailor his play properly to opponents, not a good hand reader, etc. I'm sure he's a winner in the games, but he also got stacked with open trips no kicker in this session. I'm not sure if it was a situation where I would have called or not since I wasn't really paying attention. So obviously not world class, but not a donk at all either. Numbers are 33/12 or something over 100ish hands. Only goes to showdown around 20% or so. So somewhat weak postflop.

What is his hand range and is this a good spot to bluff? If so, how much?
