In hand 1: either check/raise the flop (since you decided not to Cbet the best hand) ...or, if you just check/ called then why the heck fold to his PSB on a blank turn? he now thinks he has the best A and is trying to value town you. take his money.

In hand 2: you are against a station and flopped a monster. At least put in a big as heck reraise if not a shove. don't wait until you miss the flush on the turn to have to let your children drown in the pool when villain does the shoving for ya.
