$10/$20 really dumb turn spot

[catcher193]

Villian is Empire2000 (Roman on here I think) plays kinda laggy

This is like the most obvious bluff card in the deck ever, doesn't he bet his hands that have a 6 in the on the flop?
Also, I didn't really have a good plan for the river so this spot is just [censored] up completely, meh have at it.
