Hand 2: What do you think he's betting there? Most people aren't two barrelling overpairs there, and it really doesn't look like he has overcards. I understand it's hard to put him on a hand but most of the time people aren't getting tricky on these boards.
(If the guy is two barrelling an overpair i wouldn't expect such a large bet anyways. If I had an overpair in his position i'd probably check and call any bet pot or under on the river.
