It's probably all going in the middle here anyway - might as well get it over with on the flop and lose your stack or suck out admirably :P
UTG probably has AA with Ac and will gladly call, EMP seems to have a non A hi flush and will surely call.

Depending on stack depth you could risk simply calling but the pot's getting so big you aren't likely to get away from this hand by the river anyway with odds etc.
