Bluffed too far with A5s

1. Your hand is A5s, not A2s...
2. Why do you 3b preflop? There should be a reason for that.
3. The turn does not change anything, so why do you continue to bet? Middle pairs will call again.

Is it really wise to 3bet with A5s OOP against UTG? Keep it simple at nl2

Sorry it's a5s (It was late in the night when I posted), I'm 3betting wheelers generating odds for post flop as the chances were similar to 22+. My thought:
- I'd expect a call with something villains will not drop in a strong draw-heavy flop.

This is not a draw heavy board in 3b pot.
If I understand the flop cbet, I do not get the idea behind the turn bet.

I don´t mind 3 betting this preflop. Bet the flop, then give up.

I don't understand any of the chosen actions here

I would not 3bet this hand. Actually this is a standard fold for me vs UTG. However calling or 3betting might not be very bad.
OTF you are playing vs UTG's 3bet calling range. You are holding a bottom pair. You won't have any fold equity vs his range...
OTT betting is just not good.

I don't play this way, but if you insist on playing this way you must fire turn and probably river (definitely river on this card if you fire turn). It is on the later streets you have fold equity. Unlike my fellow posters, I believe most pairs, except maybe AK will have to fold, at latest by the river, and this would be a very nice outcome.
