First hand - why are you half potting with trips?
The preflop raiser didn't flop a straight, and the other guy folded out. Put more pressure on the guy on the turn at minimum. If he wants to chase down with AT, so be it...looks as likely that he called down with AK/AJ flush draw as anything else...I'm probably calling that river bet - and paying him off :(
Does a blocking bet - $2 to $3 help here?

Hand 2 - Looks like an easy check-behind; it's fairly likely that a flush chaser would bet on the end, so I don't think this guy hit - if you want to value bet it has to be pretty light or he's just dumping 2 pair or straight draw that missed (which is what I put him on).
