Hands 1-3 are from the Eureka ME 1k event. 4-5 are from a 1k side event. All analysis and thoughts appreciated. I think they're interesting anyway

Hand #1
17k stack 100/200
We open 33 from MP to 400
Young lad on btn - obviously not much live experience flat calls.
Good online reg defends bb
1300 pot
Flop 863ss
Bb leads for 750
We opt to raise to 1800 (he won't be folding any of his donking range at this stage I figure)
Btn flats. Bb flats.
Turn: To
Bb leads again for 2200
I flat. Btn flats (bit scared of btn now as he has the higher sets but also seems pretty fishy thus far)
River: 4o
Bb checks and we both check back.
Bb: T5ss
Btn: JJ
So I guess I played it fine? However I'm kinda trapped on the river if the btn bets I'm forced to fold depending on the size. I wondered if there was any mileage in betting tiny on the river to protect against a big bet from the btn? And if the flop raise is fine size wise?

Hand #2
17k stack 250/500
open to 1k with KQss from MP
CO playing about 80bb 3bets to 2600. Seems like pretty decent reg hasn't really got out of line yet.
Blinds fold we peel leaving behind 14.5k. Figure the hand is good enough to go to a flop with but I think 4bet calling might be better against certain regs. Although the player hadn't 3bet much it was kinda about time he did put pressure on now he had just amassed the stack to do so.
Pot: 6000
Flop 853ss
We check he bets 2600 again. We make it 8000 basically showing we never folding and he quickly passes.
I wondered if I have enough EV to just peel here and check jam turn? Or peel and lead big on turn to potentially level him into folding something like A8/K8s/Q8s/77/66/A5 which still has decent EV vs us.

Hand #3
28k stack. 300/600/75
Sb completes to us. He's a decent reg and been playing well.
We check K9cc. I figure it's decent enough to go to flop IP and don't wanna fold out weaker Kx 9x
Flop 57J(2d1c) he min bets 600 and we float.
Turn: 4d he checks we opt to check back after considering a small bet to set up a bigger river bet but I figured I couldn't rep the Ax flush having not raised pre and if he has Jx or 7x there's still lots of rivers we can bluff at.
River: 9d
He bets 1050 into 2750. I took it as thin value and unlikely to be a strong flush
I raised to 3600. I figured he has to fold all the flushes in his range now as given the preflop action, he won't have the A-Qx of diamonds whereas we defo can have them in our float flop range.
He calls with Jd7o
Bad raise? I had bluffed raised river earlier against someone else but it didn't get called so no way he knew my previous action of this kind was a bluff but perhaps I just looked like the young aggressive type that would bluff raise rivers a lot? I'd been the most active player on the table. But still felt my logic in the play made sense.

Hand #4
Reg heavy table 1k side event. 15k stack. 150/300/25
We open JJ from hj to 750
CO calls (German reg who hasn't got out of line).
SB calls (another reg. pretty aggro).
Pot:2600
Flop: 568rainbow
sb X. we bet 1800. CO flats and sb folds
Turn: offsuit 7. we check and CO bets 3500. We have 12.5k back and the pot is now 9.5k with his bet.
Can we do anything but fold here? He may bet TT for protection but that's basically all we beat here and he doesn't really have any bluffs?

Hands #5
Same German reg opens UTG to 700 it folds to us in the bb and we flat with AKdd (playing 40bb don't think 3betting vs a UTG range is a good idea here).
Pot: 1700
Flop: AQThh
We check he checks back. So I immediately take sets out his range
Turn: Ao
We bet 1200 and he calls
River: 8o
We check to induce a bluff or a bad value bet from AJ which I'm guessing he checks back flop with fairly often. But I think I may have missed value here by not betting. And I also think I could check raise and rep missed hearts myself and get called by AJ occasionally but opted to check call a bet of 2500. He had AKo. Really not sure about my overall line in this hand so would appreciate thoughts about all streets.
