100BB stacks. A very shallow-thinking player limps UTG, you're UTG+1 with KK. You raise to 5BB, everybody folds, UTG repops to 18BB. He's a regular, and you have a note from a previous session that he limp-reraises AA, and you haven't ever seen him do this with any other hand.

Is this kind of player rare? Certainly! But if you were so lucky as to run into him, should you adjust so that you're prepared to release KK preflop? If you've logged enough hands with him to consider "limp/rr with only AA" to be a SOLID read, then of course we have to fold don't we?

The key is to know that this is 1% of cases (even probably less online), and that routinely you're not hesitating to get it in PF with KK. I get the point from all of you that you're just trying to hammer home the correct play for some situations that should become routine, and not to let some cooler/bad beat make you believe otherwise.
