Speaking of preflop Raises - AA...

[Talking Poker]

Playing in a tournament where everyone has equal sized, fairly deep stacks (40-50 BBs each), and you have no reads on anyone: You're sitting in mid to late position and look down to see AA. The second player to act opens the pot for his standard opening raise of 3x the BB. The action folds to you. What do you do?

Yes, I realize calling here is a good play some of the time. But what percent? 10%? As for the other 90% of the time though, exactly how much do you reraise?

The reason I'm asking this is because I think I may be leaving some money on the table here by reraising just a little bit too much. I'm not sure. So, what's your standard play here?

Also - exact same situation, but now it's a cash game and everyone has 100 BBs sitting in front of them. Now how much do you reraise?
