3 of a Kind
Seems like the live players where you live is the complete opposite of where I live..Live players are a funky bunch. There is a "not exactly small" group of players whose 3-bet range is limited to EXACTLY AA. If I identify such players (and at 1/2, they take up probably half the table), I fold to almost any 3-bet, and continue to do so until I see a reason not to (like seeing them 3-bet with something other than AA).
Tournaments are a different story. Maybe in a very rare bubble situation or a weird massive multiway as described above, that's about it.
