i think this spot is close. a two-card flush draw is a strong hand as flush-over-flush is somewhat rare. however, it's hard to imagine a lot of hands that have hit this flop that haven't hit it hard. one of the aggressors probably has a hand like A7 or 88, but are all of them going nuts with 1-pair hands? i'm not sure if these villains are loose enough to have two pair, as they would have had to limp 74/72/42. if someone has a bigger flush draw, i'm drawing nearly dead. if someone has a set, that cuts into my equity significantly[**].
despite all the negatives, the pot is getting big and many things are uncertain, so i chose to call. further action in my next post, but i'm interested in further discussion about the flop decision.
[**] just to get an idea, compare:
