Do you like "just calling" w/ AA from EP?

Sometimes it can work out. Other times it will bite you in the ass. Yesterday I was playing a sng online and got pocket aces utg so I checked it. Blinds were 25/50, Someone late in position raises it up to 200. I made it 600 and he called. Flop is QQx. I check, he checks. Turn is another rag so I go all in. He calls, turns over Q7o. I don't know why he called my re-raise, but obviously I wasn't happy.
