This is the only hand i've played with villain, no stats or anything. This is Rush.

When there's a paired high card otf, I usually don't go for three streets of value cuz it's a WA/WB situation, and I don't want to get raised. So I usually just check it back. Is that right? Or would you b/f?

The T ott is not a great card, but I want to start getting value from worse one pair hands.

When he slightly overbets the river, I think I'm only beating a bluff. Fold river?
