We get 8899cc in sb.

.10/.25 eff stacks 25 (hero has 40).

one utg limper, utgplus1 raises to 1.10. Folds to SB. I decide to raise pot to 3.80. Thoughts? I do it for deception, etc.

Utg folds, villain calls.

Flop is T72

I lead small, $2 into about $8. SPR is about 2.8.

Villain raises pot. Thoughts on villains range and our play and if we can ever find a fold here?

I think it's just a fold pre unless players involved in the hand that are likely to see the flop are very weak.
Calling is ok but you are gonna have to play OOP, flop poorly overall, only get two streets usually when you flop a set, and get stacked sometimes set over set.
3betting seems even worse, you likely isolate yourself against UTG1, not great flopability, it's just a bad hand.

Bet big and stack off.
Pre is really only discussion.

Don't 3bet this hand, it doesn't flop an even enough distribution of equity to make lots of short SPR decisions easy, i.e. it will be very hot or cold (flop a combodraw or set vs. complete miss).

As played don't bet so small, it doesn't make sense to do that with any of your range.

3betting 2pairs is fine, especially when they are connected like 8899. 2pair hands play better in 3bet pots anyways.
I wouldn't 3bet perhaps utg open but since utg limp and then utg+1 raised pot his hand isn't nearly as nutted as open from UTG.

Leading 1/4th pot on the flop however screams weakness to me.

How played, never fold the flop from here on out. I would open more than 1/4th pot also as it screams weakness

What are actual stacks? I imagine you're 100bb with UTG+1 but get the impression UTG is short. Either way, default play in this spot would be calling pre. I understand your reasoning for the 3b, but I don't think you've chosen the right spot for it, particularly at these stakes. As played, flop sizing is horrible.

Flop bet size is at worst a small mistake. First to act, checks and tiny bets tend to be quite close in EV.

Call preflop. If you are going to 3bet this hand and get a 4bet you have to fold.
I like to check/call the flop. Villian is raising with sets and overpairs or/and with nutflush draws, so we are flipping here at best...

Why are we gonna have to fold to a 4bet? Vs AAxx we are getting 35.08% with out 8899ss which is worst case scenario. We need 33% for it to be profitable.

Without going to deep into math/ranges stuff here playing a 3 bet pot against one villian oop with small/middle double pair hands is better than playing a 4 bet pot oop and put more % of our stack in the pot. The reason is, if villian is reraising not only AAxx hands, we are not sure if we are not against bigger set on flops like KQ8 or K9x...
How many times we hit the flop hard and how many times we are missing it and have to give up?
For example we are calling villians 4 bet. Flop is A9x. We check, villian is betting big. What we are going to do?
I like to play overall small ball poker and keep the variance small, so I like calling with this hand and not 3 betting. But thats my opinion.

I never said playing 4bet pot is better than playing 3bet pot. Ofc we don't want to get 4bet in this situation. I just said that we can profitably call a 4bet if that happens. And because our hand is too strong to just call an open there is only one move left.

If you are instantly afraid of villain having a set with any overcard to our set then you are not playing the game with a clear mind.
