why would you want to shove over button anyways? you're just going to push the big stack out of the hand...

Just make a normal raise, button will call with any Q any K, and hopefully with enough in the pot BB will call as well.

weak bet by bb, cold call by you, shove by button, call by bb, over raise by you = huge hand. you're just going to let him play "perfectly" and fold whatever AKAQ hand he might have.
