UTG with AA in very loose 10/20

[Michael Davis]

Given your description of the action, which is highly unlikely to actually be true in any real game scenario, you should definitely open limp. To open raise in the situation described is very bad.

The advantage to open-raising is that it isn't so obvious that you have a hand like AA, but giving up this information is worth less than the five to seven extra small bets you're getting in the pot right away.

Of course, I simply don't believe your conditions. Usually, the decision is closer than you make it.
