Hand 1:
Your flop bet is huge.Board is not very drawy,so you want weaker hands to call you or bluff you.You posted no reads,so not much thing we can comment on here.

Hand 2:
Watch out for the min raise.You call the min raise,but c/r the turn?Im pretty nitty,so i usually dont make this play.And then you check the river??

Hand 3:
Reads or Stats?Flat calling flop and evaluate turn would be fine.Need some read on folding on the flop.A lot of combos that villain have that we beat on the flop.
