I'm just happy to see an AA hand that isn't just another bad beat post, and actually has some educational value to it. Advice ... what everyone else said.

As for doing better against better players, this is of course theoretically possible, but if true, it isn't because you are a good player, but because your game just happens to play better against players that aren't total fish than against the total fish. If you don't have the ability to crush the total fish, if you get into a game against truly good players rather than the ones that are marginally solid compared to fish, you will get ripped apart. Why? Since you don't have the ability to adjust to different players well, the truly good players that do have that ability will pick up on your game and run circles around you. It is always better to learn to beat the worst players because you will encounter them at any stakes you will ever play.
