Thanks for all the feedback. These hands were played by me.
Hand 1: This is one of the few times villain has checked back the flop in spots where it goes raise/3bet. At game speed I planned on c/r'ing most rivers because he could be running an unlikely bluff or just played his two pair hands weird. On reflection I don't think he's ever folding better in this spot.
Hand 2: Thanks for all the feedback. This is just FPS on my part. I butchered the flop because I thought the flop would get checked back. I was super confident villain would barrel the river so just made the call to c/r the river for tilt value. Not 3/betting this spot is pretty criminal and lighting money on fire.
