uh...well, I beg to differ with Melancholy.

When you get reraised, you don't necessarily have to punch all in, but you should still raise it again, at the very least. Depending on what type of table you have, punching all in may very well have a "boy, he's all in. He's gotta be bluffing. I call with AKs or JJ" mentality on your opponent.
But calling isn't the best option in teh world. You're letting hands that might have just reraised to see where they stood see a flop. Hands like AQs or something that somebody might try to reraise. Then, when the flop comes rags and you bet, they fold. No more money to you.

YOu need to reraise a reraise to your raise; they've already shown they like their hand. Make them pay to see it through. Hands other than AA will call.
