That was the only thing I was going to mention,

AK raised to 9BBs the first time and 6 BBs the second time you are loseing a lot of value by pushing everyone out. You will only flop a K or A 33% of the time or 50% by the river as long as you keep this in mind for when it does miss you shouldn't have a problem (Be ready to fold it post flop if you bet out and meet resistance).
