Villain is 76/16 idiot
I feel like I might as well join in the fun here since there's a minraise and call, I'm in position and if I hit the straight I can get a lot of value. I don't mind seeing a cheap flop here.
The flop is pretty useless, but everyone checks. Fine by me. Villain raises the turn, but around 1/3rd I'm not sure what to think. He's obviously not thinking hard enough to induce bluffs so I figure maybe he has a ten and is scared of the flush, or maybe he now has a backdoor flushdraw. Either way, I think my odds are okayish since the guy is pretty stupid.
Hitting two pair on the river is pretty lucky but it also completes his flushdraw. I guess he doesn't have that since he bets so small. I'm still a bit scared of it so just call his tiny bet.
Maybe the call on the turn is a bit borderline?
