25NL - 3betting QQ twice, and 88 under heat

Hand No.1
Villain is a nitty 11/9 and steals at 30%. I decide to 3bet, putting him mainly on steals...and he calls. Can I shove this flop? If not, what is the best way to continue?

Villain is 18/12. I 3bet and he/she calls. I bet the flop...they call. I check turn to control pot...they check. They bet river...can I call this 50% river bet?

Hand No.3
Villain is in BB and is an 18/9 but does not like folding to steals (50%) and he knows I steal like a crack monkey (71% this session) so he calls. On the flop I have an over-pair and and open ended straight and backdoor flush draw. Villain is also a 6% 3better so I figure he would 3bet me with 99+ AJ+. When he raises my donk bet...I am thinking he just does not believe me? I call...he fires the turn and I fold. Any thoughts on this line of play and how you would change it?

1. "I put him mainly on steals" is not an answer to "why'd you 3bet?". I'd check back flop because only sets and AsKs will continue most likely and maybe KQs which is very unlikely.

2. As a preference, I always bet these Axx boards in 3bet pots like half pot. River is kind of gross. I wonder if you have seen him minraise preflop before? I don't think you can go too wrong with calling or folding. It's hard to see a worse PP play it like this but I'd need actual reads, not just stats.

3. You have to know his 3-bet tendencies. At a lot of stakes vs. 6% 3bettors they don't have just a value 3-betting range meaning they 3-bet say JJ+/AQ+ but also lower SC type stuff. I think you played it pretty well overall because I really cannot see him having a worse hand unless it's A7. Obv. if you know he's aggressive he could be doing this with a lot of draws which makes his line pretty good because he can buy a cheap river card which also allows for FE.
