Sorry I tried to post hand history but it keep saying invalid hand. I'm doing something wrong

What is the first thing you think about when deciding cbet or not in this spot? If I cbet 1/2 pot he needs to fold 33% so is it a good approach to see in equilab how many combos he is folding and if he folds more then 33% then we should cbet here AK?
