Some losing hands - bad beat or bad play?

Thank you all for your replies!
btw, eugmac, is this the wrong section to post hands and ask for review? If so then I'm sorry..
I thought about these hands myself but now I understand better what mistakes I made. I also had my KK busted to AA later.. and my question is that approximately how tight opponent has to be to seriously consider his 3bet a sign that he has AA? So far my approach was to consider every KK vs AA loss a bad beat but that happens more that I'd like to...

No, this is the perfect place to post hands, but you should edit out the results - i.e. what the villain had - in order to keep the responses as unbiased as possible. Results are only good for the bad beats forum.
