vs 20/15/12 over 60 hands

This is probably a big leak for me as I tend to call these turn shoves on these kind of boards a lot. I just tell myself he could have slowplayed QQ vs 3b pre because we are very deep, or he picked up some kind of Tc9c, AJ, KJ. Still does not make sense with AJ-KJ as I block those hands and he should be scared of QQ-AA etc. Also in the moment I didn't think he would shove this big with a set, maybe raise a bit smaller.
