folding the turn seems ridiculous. even in the absence of showdown value (and we obviously have showdown value), we have a nut draw that's gonna get paid off whenever it hits.

also, he won't always 3b AK/QQ preflop. in fact it's not even the correct play to make against a lot of regs.

i call the river without too many reads against a 10nl reg. tbh, i don't think there's a range that i can put him on that we have good enough equity against to call, per se (especially since he's never bluffing). i just think it's such a small amount that some relatively unknown 10nl reg can show up with something weird often enough to justify a call.

also, i'm forced to applaud him if he's really enough of a thinking player at this stake to recognize how weak our range is and go for a <1/2 PSB on the river with a flush. if it were someone expected to be very good, i'd be more likely to be scared of middle sets and better and less likely to put him on medium-strength hands
