Well its 6 handed so a ace is pretty strong and your in the cut off, So you should loosen up your game and if your not raising preflop(which i suggest), just make the call and try and make the nutflush and take down a big pot.

edit:
seems im the only one that would suggest limping. but heres the stages that i suggest in my original post.

1.bet
2.if you cant put in the bet pf limp
3.last option would be fold.

I've been to the casino 3 times and the power of limping in with suited aces are amazing because they cant put u on a ace thats why i think limping is not such a bad play. But thats also requires a read on your table like do they still go in with rags? But yeah thats my advice.
