hand 1 is insat fold. You dont beat anything hes going to 3bet you with. (but lol at stars jokers still limping one pair hands)

hand2 i would bet so much on the river bcoz he may have called you down with a queen. possible c/c river.

hand3. I dont even bother here. So many hands can be limped here that it really isnt worth bothering without a really strong hand here. There are better positions to exploit.
