You'll be playing it 100% of the time so no not Tag, and postflop depends on lots of factos such as villain type and board texture and the action. If all i got dealt was AA everyone would have me tagged as a maniac.
Ahh, i have lost more then i like to admit with the AA's. still always try to play them aggressive while reading the board as its really only a mid hand unless your turning one off the flop too. pairs a pear at the end of the day.
I play the pocket pair AA - aggressively. One of the main rules of the game with pocket AA - do not slowplay. The main essence of the game with AA is that the fewer opponents remain in the game, the greater the probability of winning.
Me I won't let any one see the flop cheap at all. i will make them to pay to see the board. I have slowed pocket AA and i ended up getting beat which was not cool. so some times i will push if some one raise .
