Ive gotten AA close to 500 times since I've been grinding 4nl. That is over 100k hands since the beginning of November. Playing AA postflop can be tricky. You have to be careful not to commit yourself with the ultimate top pair top kicker. Play it the same way you would top pair top kicker vs drawing hands or a lower pair etc. The idea with AA is to do everything you can to get the money all in pre. Start by putting in the raise, and hope others follow suit with 3betting and 4bettng galore. Here are a few looks into how I played AA postflop. These examples show when i went for pot control, when i played for stacks, and when I folded.
