Basically, without reads/stats other than this guy is a complete fish, I'm paying him off here. I have seen some of the most random and retarded shit get shown here. Obviously, if he plays a set this badly then I suppose he can have my money, especially when I'm damn near the top of my range. That's because on average if he does make this play with a set, I won't be paying off when I have a lot of weaker hands, that I'm gonna have more often here.

Also, we only need 44% equity to have a BE call here. If we put him on a relatively tight range (basically the top of his range) {77,TT,JJ,KQ,AhKh,JT}, then we have a call with 47% equity. If he has more flush draws/straight draws than this, then our equity increases and a call becomes more apparent. And I don't think that we can put some retarded bluffs or shoves with worse out of the question against him.

Also dranger, I know you posted saying he likely never does this with <top pair; however, you only have 25 hands on him. I'm wondering if this is an assumption you are making based on his AF, or if you have some other relevant information, such as another hand he played in the same manner, etc?
