4$ 180 sitngo stars, do we trap here?

I'm 100% sure he has an ace that is not paired.
Do we trap here or shove the turn?

ok, i posted it on other forum and ppl told me that i shouldnt be 100% sure that he have ace but by the game flow i felt he has ace here

anyone mind telling me why calling here and shove river is bad?

I like a raise to 2600 here and shove any river if called.

99?

he likes his hand, get it in asap

He invested half his chips already, you should get it in on turn.
