I'm putting him on an ace, I would surprised to see AK, but I'm expecting to see another ace and hoping his kicker is lower than mine and that he doesn't hit it. However about 10-20% of the time he'll have some really random hands as well.

Normally opponents don't seem to make these massive overbets with a set or 2 pair so I feel very comfortable calling, really only fearing AQ.

BTW, it's probably better if you posted the actual hand results afterwards so that the responses can be more objective.
