3-4 raise often talks about AA hand, so it is too late to fold and wait for a new distribution, where you have more control. I very often find themselves in a situation when I was a thorn dumping AQ, AK, QQ, KK, in a similar deal and I was punished for it. But it is also important at what stage of the tournament you are playing, and the reputation of your opponents. For example, there are situations when player C can have a trash hand on prebuble, when a lot of players with a stack above average become more aggressive. In this case, I would have called. But only if I know that he probably nothing.
