Are the following statements true? I've picked them up somewhere.
1) If villain is overbluffing a river spot, let's say he's a volatile fish, we should call all bluffcatchers.
2) If villain is underbluffing a river spot, let's say he's a nit with low postflop betting frequencies and nitty preflop stats, we should fold all bluffcatchers?
3) Follow-up question: How does fish making polarization errors, betting with weak/medium made hands affect this concept?
