Pre-flop sucks in the second hand. Don't minraise pre-flop...raise bigger. And in the first hand your turn bet is kinda small.



I probably shove the first hand but check in the second one.




Edit:

In the first one I believe it's a high liklihood he has a T and JT-KT seem likely. He checked all 3 streets so he doesn't seem like he has better than TPTK.

In the second one a flush draw seems very likely to me which can easily come with an ace expecially raising UTG pre-flop and even if he doesn't have an ace he's not calling with a busted flush draw and I can't think of much that you beat that will call most of the time especially with that ace out there on the river now.
