[TheDespot]

The call and then push seems more suited for tournament play (freezout, that is). In the cash game the villain is probably going to feel committed since he's already put in a bunch before the flop and won't have to call much more than he's put in (and he knows he can reload if he has to). In a freezout tournament, every chip is precious and pushing the flop may make the villain fold a live hand that may not have been folded in a cash game.
