Hihi.
Like flop and turn. Most of his flop calling range is going to be mid pairs that will fold, random floats, flush draws. Basically just betting to win the dead money.
When he calls turn, I think he mainly has stuff like K9s, KT, KJ that's scared of our KQ or AK. Slowplayed 77 is also possible. He might be bluff catching occasionally and fold on the Q, but don't think 3 barrelling is going to show a profit here.
