The thing to be aware of is some people are pushing high pockets straight out because they often get a call from something like 66-JJ AQ AK AJ AT KQ.
Possible, but I can tell you that after a couple of weeks playing at Bodog to clear a huge bonus, I have never seen this situation arise. The percentage breakdown of the hands I've seen anyone push PF like this has been something like:

77-JJ ~%50
A2-AK/KQ/KJ/QJ (remember this is Bodog we're talking about) ~30%
Assorted garbage ~ 20%

If the individual read hasn't revealed itself yet, then don't lose a stack over it.
I do like this advice, though.
