Well several situations can imply that you make the call for the difference.
One being that if say there are 4 callers at the table and noone has opened the pot there is 11k in the pot ,understand the theory ???
It cost you two more to see A flop unless the big blind opens at which point you can fold.
But you have to look at your odds
to at least see the flop in that situation.
I dont like to put off the image at the table that you can bully me on my blinds and take advantage of my blinds because you figure I will fold.
Most times than not I find myself at least making A call in the small bling in unopened pots.
That is just my honest opinion.
