How do you play JJ here?

BU is playing 23/21/12 over 100 hands sample so he's probably a reg but who knows, small sample.

Preflop easy squeeze 3b for value, JJ can use some protection against overcards and it's good to thin the field.

Flop I don't use 33% sizing on these boards. I usually go 50-66%. I don't think it's connected enough, especially when rainbow, that I want to do a lot of checking, but I might be wrong, BU has nut advantage with sets.

Turn I jam for value and protection but I don't expect to get called by a lot of worse hands tbh. Am I just overplaying my hand here?
