Villain in this hand is one of the worst players around in this player pool. I know him from the 1/2 streets and he's a big loser there. Never seen him play 2/5 before. He's an Asian man about 55 yrs old. Plays too many hands, makes bad bluffs, value owns himself constantly. He will continue on most flops he has any piece of for any reasonable bet size. He will bet when checked to with air just because. I could go on and on about how bad this guy is. We're about $500 effective here.

I think it's pretty straightforward but not sure if I can take a better line. Perhaps just leading the flop or check-raising the turn? This board is super wet obviously and I'm OOP so I don't mind just potting the flop and taking it down. Since he likes to bluff though I felt this was a good candidate to check-call down. River is just a puke fold nothing to say there. I'm calling almost every river that isn't a diamond or Tx.

I like your line
