Some badly played hands from 5NL

Hand 1:

Villain is 35/7. This should be a fold preflop, I think I was concentrating on another table and just clicked the button to complete without thinking about it. I should have raised flop and turn here right?

Hand 2:
Same villain as hand 1. We are both deep so I am playing this for set value. Given the weak bets relative to pot size, should I be raising it up here to try get a fold, folding, or trying to see a cheap showdown?

Hand 3:

Villain is 70/23
My reraise on the flop is very weak, this is deliberate as Im nervous of scaring the villain off, and am also trying to see if I can induce him to bet again.

Hand1- It'd be helpful to know how this player plays post-flop, aggressively or passively? You might consider posting aggression factor of the player and also how many hands your stats are based on in future posts.
Anyways a player like this could easily be taking a stab with any pocket pair or even a 9 and attempting to rep a king. I like the check call on the flop because it gives him a chance to either catch up a little or feel more comfortable about the strength of his hand and at the same time it makes you look weak. If you had reads or past history that suggested he would call a check raise on this kind of flop in a limped pot with less than a king, then it's good. I like your play on the turn and river and once again given reads I might be tempted to raise even more on the river because he's shown enough strength and doesn't want to fold.

Hand2- Calling pre-flop is pretty dependent on your reads and how aggressive/loose the op is post-flop. Since you decided to call for set value against him, I'd either be folding or raising on the flop, depending on his tendencies. Calling is bad because even though we have great odds, our equity is terrible if he's playing a range like Ax, JJ+.

Hand3- Open limping is an extremely weak play, unless you knew this maniac was 3BETing you light very often and you didn't want to fold. As played I am 3BETing this flop much bigger. Don't be nervous about scaring him off, because there are a lot of hands he can be continuing with on this flop. Post-flop reads are helpful in determining what to do.

you can raise way more on hand 3. obviously he needs a good piece of that board to continue on.

There are very very few spots that i would advocate small bets/slowplaying but hand 3 is one of them. I like the small flop raise, but i would for sure check the turn. Given that we have straight and flush blockers, there aren't many draws he can really have here that will call both the flop 3 bet and the turn barrel. He might well bet his Ah+pair hands if checked to tho, and feel compelled to call a shove since he'll be getting a decent price if he makes a decent sized bet.
