First of all, this isnt a bad beat post. My main question here is what do I do on the turn? This guy just donkbet 30 into a 900 pot when the flush came after a raise and coldcaller on the flop. What are the chances one of them has the flush here? If it were HU, I'm probably just pushing here, but I'm actually just as worried about MP3 as I am BB. In retrospect, I probably should have made it a little more on the flop as well right?

No reads on these guys yet.
