Oh yeah, the results for this one: I folded after a bit of a think.

[6s] for the higher flush.
It seems to be quite trendy to reply to these posts ("I have <set/flush/straight>, board makes possible <better hand>, dumb opponent moves all-in into small pot. Do I call or fold") by saying it's an easy call.
Problem is most such pots I've seen or read about, the dumb opponent has had the hand in question.
I think a combination of empirical evidence, the fact I've seen him overbet a big hand, and the fact he might be on slight "catch-up" tilt, makes it pretty likely he has the flush.
So let's look at some numbers: say he has a flush... there are 6 cards left, 3 of them beat me; so I'm behind 3/8 + 5/8x3/7 = 36/56 = 65% of the time.
Now if X% of the time he has a 2:1 draw, and (100 - X)% I'm behind 65% of the time, then with 6:5 odds, I need X*0.3 + 0.65 - X*0.65 < 5/11 for the call to be profitable, ie X > 57%.
So I should fold if I think he has the flush > 40-45% of the time.
But I'm willing to concede I may be a weak tight idiot who's results oriented
