General AK reraising question

[orlov]

This is no specific hand, just a general example.

Assuming NL25 vs average villain with 100BB stack.

I pick up AK in the CO , utg folds, mp raises to 4BB i reraise to 12BB, he calls, everyone else folds.

flop comes rag, I dont connect. I cbet about 2/3rds of the pot, I get called and then usually check behind on the turn and have to fold to the river bet. If im oop I usually c/f on the turn.

Now my issue is that when there is no a or k on the board I literally always get called, Villains just seem to never let go of their hand in 3bet pot. Just seems to me to be a huge leak to me to cbet with ak in this spot as I get called even on the most rag flops.
