Hand 1:
I like a bigger turn bet of like $170ish although I doubt it affects the hand.
As played, river fold seems fine as long as you're sure you have KK/QQ/A
K
here sometimes and check that flop still.
Hand 2:
I would just lead the flop and potentially go for a check/raise on dry turns. Checking flop makes it hard to control the size of the bets that go in the pot and leads to awkward situations where the turn goes check/check and you're not sure whether to induce a bluff on the river or go for value.
