So I know my call pre is a bit loose but the blinds are both fish, no stats on their 3b tendencies as such but they don't stand out as aggro. Is this basically always a flush on river for this size bet and he's trying to extract max value from a 5x or T9 that can't fold?

I don't see what hands he would call twice here with then turn into a bluff either. And even if he is taking a weird line betting T9 we're still beat. Don't think he does this with 5x to push u off a chop so it's just a huge negative freeroll and easy fold?
