In hand 1 I'd tend to bet the turn as well because the turn is a brick for most of his holdings other than two pair and I won't get any value from a straight or flush draw on the river
As played I fold the river

hand 2 is read-dependent because some shortstacks won't do this unless they have AA/KK and some will do this with K8o and you have the problem of the other guy behind you
