His steal% is very low, his fold to 3bet is very low, so basically he does not steal, he raises his normal raising range in LP, and this range is strong so there is a very considerable chance that he will continue facing your 3b.

So 3b pre. As played donk flop and shove if he raises. As played bet/fold turn. Your Kc isn't worth much when the Ac is out there. As played fold river.
