hand 1

shove pf or fold

it is ok to fold AKs pf if villain is a serious rock. i prefer a fold pf. super tight players dont 4b without KK/AA

hand 2

raise flop to $2.10
full pot turn

his range is gonna have to fold most of the time to show profit here.

i also strongly disagree with the advice above about 3betting this hand vs. utg raiser... vs CO its ok, but not utg.
