it's always a pleasure getting AA or KK dealt. With this top starting hands I try to get as much value as possible. But often it is dissapointing. Getting them in BB and everyone is folding to me, o.K. Also a 3BB openraise in other positions end mostly in folds. I tried slowplay which leads often to be beaten by trips, straights or flushes. I don't do this anymore...
Of course I 3bet after a raise, but I think there could be more success with this starting hands. Mostly I win the pot, but the potsize is low, If I loose than the pot is high.

I know, much is depended on villains behavior, stacksize and position, but what are your general strategies in cash games to get a maximum of value with AA or KK ? Thanks.

If you're playing tight, especially in a short-handed game, then you should forget about an early position raise—everyone will fold. You have to limp. Ideally, someone raises, and then you can re-raise, and take down a sizeable pot, then and there.

All AA does for you is give you the best hand, pre-flop. The more cards laid down, the less likely your hand is to be best. Because all that you have is a pair. Your best chance of improving is a set; which is very unlikely.

Build the pot, pre-flop. Make inferior holdings fold. Post-flop, if you don't improve, then cease building the pot. If you're out of position, and there are lots of draws on the board, then you're short on luck. Cards are nice, but position is king.
