A different spin on these hands...

Hand #1:
First of all: You need to get better reads on your opponents before playing too tricky. Thus, the three-bet was too small because you are not narrowing this unread players range enough..

Nevertheless, is this the kind of player who is going to float you for two streets with complete air? His shove on the river there is either a bluff or a better hand than yours..
If he's bluffing and puts you on something like AK or weak pockets, it makes more sense to semi-bluff that turn and put you to a tougher decision... In most cases, villain expects you to bet the river after flatcalling the turn, so this is definitely not air.

To a good player like the villain here, it is rather obvious after $160 on the turn that you have a big hand and there's no value in SHOVING this riv for him with QQ, JJ or A9. QQ probably 4-bets you preflop as well, limiting that option.

Put these pieces together and we can easily fold on the river here and save $387.
