This is an impossible situation, and a good case can be made for pushing, calling or folding. If you're both very good, agressive players, from his perspective, you could have anything, and from your perspective, he could have anything. The "I don't think he'd risk that much of his stack on a bluff" doesn't apply to great players. If you think you have a serious edge over the other players at the table, you might be better off folding, since you could be way behind. But, if you fold, you're sending out a signal to any good aggressive players at the table (according to you, he's the only other one) that you can be pushed around. You could also be way ahead, and this could be your shot to accumulate a monster stack and cripple your only real competition at the table. Or you could be racing. He could have a big draw, in which case the best play would be to call and then push if the turn is a brick.

Look down at your watch. If the second hand is between 1-20, push; 21-40, call; 41-60, fold.
