Very good observation... why would you bet if you wouldn't get a call from a weaker hand? Of course, this is assuming worst case scenario. But then the perfect play with these assumptions is not going all-in, but probably betting as much as you need to eliminate draws.

Of course you're going to take this calculation and apply texture and loose the players are... so why not start there? Although I can see how against loose players calling and then going all-in with a pair of aces will probably be EV+
