That reminds me of a typical situation:
One player raises/folds too nitty once, twice or three times... and, suddenly, you shove over his openraise and he calls with ATo...
Obviously if he tanks with AK the EV+ of your shove is more than proven, even with wider range...
But, in this situation, against weak player, I think sometimes is better to call and play in position.
You can manipulate villain by calling, shoving good boards with more FEq than preflop, or folding without risking you tourney. Don't forget this is a high bubblefactor confrontation, you'd better play against the other player than the bigstack.
Let's see how it works on HRC:

It recommends that you call (+0.65) better than shove (+0.55)... But it's based on this villain ranges: 28% openraise and 8.8% call shove. It sounds pretty standard.
Personally I think I shove A8s a lot of times in this situation, but always seems good for me to remind icm implications, and tend to be more careful against chipleader.
