Hand 1: you need to be getting almost 18:1 implied odds to call if you think he has a bigger pair. this is clearly not the case

hand 2: you are only getting 1.5 to one to draw to your straight. given read that villain can fold an overpair this is a fold

hand 3: you are getting about 2:1, and are probably a 3:2 dog, so i call

hand 4: easy fold

hand 5: this is an easy call
