Hand one, preflop is fine, but I dislike the raise, since it's unlikely that worse hands will call our raise (usually 99+), or at least flush draw, so your equity really isn't good unless villain is a total fish and will call your shove with overcards. I prefer flatting on flop, since we do have position, and reevaluating on the turn. What kinds of hands does villain check on turn? Bet on turn? You'll have to make your decision based on that.
Hand two: probably better to fold pre-flop. On the flop, it's probably better to lead, since micro-stake players have a tendency to call bets like this with not-so great hands, which they might just check if you didn't bet. C-c wasn't that bad though, if you think they are aggro. On turn however, I don't really understand the check-raise. What kind of hands would call that? Only flush draws, or made hands that have you beat. Instead, it might be better just to lead out on the turn, some kind of protection bet, since if villain also has a pair of kings, he's gonna be scared of the 7 and just call your bet, and making flush draws pay. As played on river, you can only check/fold.
Looks like button is a pretty big fish.... Hard to put him on that hand considering your action.
You seem to have a habit of making raises and check-raises with marginal hands. Next time you find yourself in this situation, ask yourself, why are you making this play? Is there a more profitable play?
