the QQ hand despite what you think, folding isn't bad
his range is polarized to nuts and soulcrushing draws

why is that? it's because we're UTG so he's putting us on a REALLY STRONG RANGE
if he doesn't have at least ace high flush draw he's not going to be sticking it in, he's probably going to just call the cbet because he feels like he has really good implied odds

is folding here with queens exploitable? yes
BUT WE'RE EXPLOITING HIS TENDECIES BY FOLDING
you said he was a 19/16 which means he has pocket pairs, suited aces, suited connectors and AQ in his calling range, but when he c/r this board he's not doing it without a huge draw or the nuts
which means he crushes you when he decides to c/r

I guarantee you this is his ENTIRE RANGE:
Board: 3h 2c 5c

Hand 0: 77.641% { 55, 33-22, AcQc, AcJc, AcTc, Ac9c, Ac8c, Ac7c, Ac6c, A4s, Ac3c }
Hand 1: 22.359% { QdQs }
