Hand 4 is the toughest methinks (on reflection).

Reraising practically turns it into 72 off. You're not thinking about the strength of the hand, you're re-raising basing on the crappiness of opponents hand. (You expect to win without showdown either preflop or with a CB.) 33 likes implied odds and they are being substanially reduced by raising.

You're not throwing away money by folding it. Playing it for set value is possibly close to neutral EV. (You only win the pot + a CB most of the time.)

I like calling, with the intention of folding sometimes, hitting a set sometimes, and stealing the pot sometimes? (Note that you'll often be stealing the pot with the best hand)
