Comment on Bluff

[Law Player]

I am wondering if I pick the wrong spots to do the all in bluff. I very seldomly do it, however, I felt this was an appropriate place. Given villian had a set or high over I assumed I would have heard from him on another street. I figured he was on a marginal pocket pair that I would be able to fold out. Advice on any street would be fine.
