Hand 1
I don't like firing turn because it looks like villain is on a draw and will call anyway. I hate river because villain's draw completed.
This guy seems like a station, bad player. He has no idea what you are trying to rep and he's just playing his hand. Don't bluff this type of guy. Think valuetown. Cbets are ok, but this is a bad spot to triple barell.
Hand 2
I don't get your commentary. SB is first to act on river.
