So I had this hand this morning in the micromillions main event and would love to know what everyone else is doing??

Its very early on and all very deep, there is a couple of absolute maniacs on the table playing 80-90% of hands and coolering everyone so I'm playing super tight (8/8 over 90hands), the villian here is playing about 25/18 over about 30 hands.

So the big question here is do I shove (or call Shove) Pre or flat at some stage? (it seemed weak aces were winning sssooo many hands)

Or any other advice on this particular spot…
