Live €1/€2 PLH Hand

[Spacer]

Live €1/€2 PLH 9 handed, stack sizes are approximate.

I usually play NL $25 online, pretty inexperienced live.

I'm UTG (stack €210) with AKo
I open raise to €7, calls from MP1(tag €250), MP2 ( loose/awful €160), CO (seems decent lag €350), button ( seems tag €300).

flop: 9 A 9 r, pot $38

What do you think is optimal line here? check call? I'm probably up against a pretty wide range of hands, including 89o+, random suited and unsuited gappers and any practically any pocket pair.
