This is totally dependent on reads/history w the villain
Against most opponents i would probably shove over the min raise pre w ax.
If you choose to set a trap as i guess you have, plan on check raising ai if u hit the a. Most players will c-bet any flop after they raise pre hu.
I definitely think check raise ai is the best line on this flop.
Sinsst WTF!!! 
Check the flop and then fold to any bet...Why? you're kicker sux+flush draw+straight draw,either way a fold would have been better not knowing what opponent has, this isn't a spot where to risk 1st place to be honest.
This is madness grasshopper. It's hu! in a rebuy tourney! w a solid chip lead! and a chance to win it on this hand!
imo u r way in front hu w this hand on this flop 9/10
