I guess today is my day to question villain descriptions.

When you say the villain is a "TAG," do you means he mostly enters a pot raising or betting out? Or is he not calling a lot preflop. The reason I ask is that many inexperienced players often think "TAG" just means tight. It changes the answers as to the right response to your question. Actual TAGs at a LLSNL table are as common as unicorns.

So lets move on to the hand. It starts with ranges. What range of hands do you put the villain on? Against most tight players, A4s is a big underdog. So of those hands, how many do you think he will fold? This is where your value will come from. Of what remains, what hands do you think he'll continue with on the flop? What type of flops will encourage him to call your cbet and what % of all the flops is that?

I realize that's a lot of things to consider for an inexperienced player. I'm guessing you didn't consider them at the table. That's why an inexperienced player should be folding without hesitation A4s to an UTG raise. If I'm wrong, then you wouldn't have made this thread.

TL, DR version: Fold pf.

TAG as in not limping often a tighter pfr to vpip range. I also give it to how he chooses and when he cbets and sizing and what situations. Overall personal image was something that I categorized in my mind as the "good player type" which like you said as an inexperienced player how can i categorize a player with so little live hands actually played in my life.

I believe that his range is pp, broadways, some suited Ax and the obvious better part of range. I believe that cause I hadn't 3bet all session, vs what I believed to be his range I could 3bet and find a significant amount of folds here (yes I actually thought this). But I won't lie part of me also thought this move was overall gonna provide me with better things in my whole image and later hands both pre and postflop, which comes again to me being inexperienced with live.

Again bad post by me he wasn't UTG he was I think in the HJ, and it folded to him hence why I thought he had that wider open as opposed to that tighter early range

Obviously you seem well experienced and im thankful for the reply.
Any tips before I play again in the future? Obviously this kind of spot probably wont be happening again.

I like the 3! pre a lot, and it's a good size.

On the flop I like a much bigger bet, 140 in to 200 sounds good. When he raises, great spot to 3! Jam expecting to have 40%~ equity in some spots against KQ hands and like 35% against AK which didn't 4! pre
