There's no exact answer to that, if he won with a pair of Aces, his team and sponsors would be satisfied.
With the most equitable hand in the game, he only has two options, which are to bet everything or to increase, both of which are correct moves.
However, with Aces in hand, do I want my opponent to give up or pay?
If he has a QT in his hand he may end up giving up, causing me to waste this opportunity on ALL IN.
So maybe the best option would be a RAISE in this situation.
If I were ALL IN, my justification would be based on my opponent's profile, if I knew that he was an aggressive player and would call with hands like QQ, JJ, KK or AK, AQ, AJ exploring this situation.
That would be my justification.
