In the first example, I would be very surprised if the button did have AA or KK. Why would he make a raise that probably will scare everyone away with a monster hand?

If he had raised to 1500, I would fold QQ here. But as this put turned out, I would push like you did. And if he has AA or KK, you are simply outplayed and its nothing you can do about it.

The second example is an automatic fold. I would not call with this hand, and I would most definitely not see a raise with it, unless I am extremely shortstacked.

Here is a little lesson that surprisingly many people dont think about: a hand like KJ is often FAR worse than a hand like 67 suited against a raiser or reraiser. The reason is that KJ is dominated by AK, AJ, KQ, AA, KK, QQ, JJ, which are all common opening/raising hands.
