First of all you have second nf blocker as 78dd makes nut flush
.
Without any reads I m very suspicious that people are gonna fold any flush live
in a big 3way pot.Although his betting into pfr doesn`t really make much
sense.Only logic hand would be top set.Best scenario would be you raise all in in order to make fold lower flush by sb and bb,and mp calls with tt.
But again not sure how often this will work,so closer to fold.
