In my experience, a big COMMITTING 3bet in this spot is AAKKQQAK from the majority of players, AAKK from nits, and 22-AAAKAQAJKQKJ from a small minority of donktards. Occasionally, you will be crushing AQ, but more often than not, the villain's range is AAKKQQAK. Why shove then? You are either crushed, racing, or splitting. The key is that he made a 3bet that makes him absolutely committed to the pot; most players wont do this without AKQQ+. You need PT to answer the question.
