If you play low limit and you are first in, bet 10% of your stack in a tight game and up to 25% in a loose game. Good if you get a call from one player and better if you get reraised from one player so that you can put him all in before the flop and use your edge. Slow playing aces always allows lag chasers and weak-tight deadbeats into the pot when they should be folding. These are the guys that draw out on you and win.
