$10 NL HE STT: Easy fold IMHO with a middling ace

4 Players left in a 6 max turbo sit-and-go. Blinds are $75/$150.

The villain "paperboy545" open limps in the cutoff seat with about 20bb in his stack. I limp behind him with about 14bb holding A7 offsuit and there are 4 players seeing the flop. We see KA8 rainbow. First two players check and the villain bets $450, or 3/4 of the pot.

Some people just can't let top pair go, especially in position and are then surprised when they are felted. Villain obviously likes his hand and what I am most concerned about
is something like A9 or A10, in which case I am way behind. If the turn then came a K or 8 I would be drawing dead.

I don't recall my read on him as far as his style of play. He can also have a hand like K8, hoping another play with an Ace will pay him off.
Not only that, but the other two players after me are still left to act. Heads up I'd be calling the flop bet at least. There is always the chance he is holding something like A3
and overplaying it, but me personally I'm done with the hand. Does anybody have a different view?

Hard to tell if you have no read about villain.

I would guess that the blinds probably have no Ace, but of course they also might have been lucky.

I would certainly not only limp if I had ace + high kicker but everyone plays differently.

My guess is you might even have the best hand but the gamble for 3/4 of the pot is simply not worth it. So I would say your fold was a good decision.

It more important to win the bigger pots.

Preflop
Personally I am not limping behind here. If CO is a loose and fishy limper, A7o is good enough to jam for 14 bigs and apply ICM pressure. And if CO is more of a nit limper or trappy limper, then A7o can just be folded. The issue with limping behind is, it allow either player behind to jam, and I dont want to call either of them off with this hand. And even when they limp as well, you are going to be 3-ways or 4-ways to a flop with a hand, that dont really love any boards, unless you smash it with two pair or trips.

Flop
I agree with the fold here. CO is betting 3/4 pot into 3 other players, and he is doing it on a dry flop with no real draws. This line looks very much like a nit/trap limp with a big starting hand, that smashed this board. And even if he is occationally bluffing with a hand like QJ or QT, you still have the two other guys left to act behind you, and they could also have you dominated with hands like A9 or AT, that they felt were to weak to raise. This is why, I dont put myself into this position by limping behind in the first place.

Limping here definitely invites aggression from the blinds. Making a standard raise is just silly; I don't like jamming either. More often than not I am folding here. I took the screenshot a few weeks ago with the plan of discussing it later on, so the hand is not fresh in my mind . In order for me to limp here I would have had to seen the villain limp with a few weak hands previously, and the blinds play rather passively. In that case I may actually had the best hand, and my stack depth is still deep enough to allow a little maneuvering (but cautiously). This was meant to really be about the post flop play, but folding pre is definitely valid.

I really don't like the limp behind pre-flop here. What hand can you reasonably expect to hit that you're going to be happy with?

As Fundiver says, based on villains ability, you could opt to shove pre-flop, but most of the time this is just going to be a fold.

Fold on the flop should be very easy, but like you say, some people can't let top pair go.
