Correct me if I am wrong. I suck at tourneys, but I do well in cash games.

But a difference between tourneys and a cash is that you are almost always at least 100BB deep in a cash game, while you are usually a lot less deep in a tourney. Since you want all your stack in, you cannot afford to skip a betting round because of the depth of your stack . And you do not want to give free cards to weaker aces. If you bet they'll call anyway (because these flops are what people who play A5o are hoping for). Get the money in while ahead.
