I think given these reads I would bet again. You have like 1.1x pot on the turn. If villain is crazy preflop and a calling station post I think it is a mistake to fear the 78xx 457x 245x. I would be more concerned about checking and it getting checked back and villain getting a free river with a hand that has equity but doesnt currently beat us and would sigh call the turn pot. This allows for them to brick river and fold to a bet. If we pot now and get it in vs. 78xx we are a 3:1 dog. If we are check calling anyway I would just bet. Running some hands through pro poker tools it looks like a lot of the hands that have us beat we are close to 3:1 / 5:2 which is approaching the 2:1 so it may not be a significant error to bet it in even if a lot of his range is just straights.

Once you raise the turn I think you just have to get it in on the turn. It looks strong, and there's only likely 2 hands that have you beat and if you are called and behind then you have equity anyway. I'm quite happy potting it there
