Superb Alien and Doc
Its remarkable how many times you see AA played very badly at lower limits(as mentioned if you're getting you chips in ahead trick and losing then thats just bad luck which will sort itself out in the long run).
Ideally I think you want 1 caller, either paying to see the flop or all in. Its here where position, stack sizes, table type, tight/loose tables etc comes in as to how best to engineer such a situation, which alien covers superbly.
Just to add one thing - pretty obvious but important I think nevertheless. That is that having had AA on the previous hand doesn't make you any less likely to get it on the next - and I seem to see a lot of players take the mentality that as they have been dealt AA it is then necessary to ensure they get a big payoff as they won't get many chances like it. This is where the trouble starts, as they will allow players to get in cheaply in order to try and draw them in, and more often than not end up losing a huge pot.
As an example I might say that an AA in the big blind who sees maybe just 3 flat calls on a 10 seater table, and might be reluctant to stick in a raise which might just see him picking up a few chips, but as is often the case picking up that small pot is a lot better than checking and running a very real risk of losing a large chunk of his stack.
