AAAK gets folded preflop by yours truly. AAKK two suited is a whole different story.
When I first started reading your post I thought you were saying that AAKK two suited is a bad hand - I was boiling on the inside that I was going to have to actually work to convince you otherwise.
PS: While I agree that AAJT two suited is lucious as well, give me AAKK instead anyday. If on this very pot I had AAJT instead - I would have lost the hand. The kings are what played for me. There are some world class players (such as TJ Cloutier) who think that AAJT is the best hand you can be dealt.
