I will never NOT 3bet AK, because 1) against people too tight for AK to be a value 3bet, it nevertheless makes for an extremely good bluff hand because of blockers; 2) TPTK is useless as a value hand and has bad RIOs against a massive nit anyway, so it doesn't play well postflop; and 3) in a looser game or late positions AK's
equity actually significantly improves vs a flat 3bet range, because a tight range consists almost entirely of hands AK dominates.
I will also never NOT 3bet AA, because it's a relatively vulnerable nut hand and I want ranges that go up against it to have very strong high-card value and very weak speculative value.
I would probably not 3bet QQ/KK in a tight dynamic, because flatting keeps worse hands in so that you can get some value out of them postflop, assuming an overcard doesn't come off otf (in which case you're basically dead and should fold unless your villain bluffs enough that you can bluffcatch profitably -- most nits don't but some better ones bluff sometimes for balance, and with a very tight range it's very hard not to bluff too much even if you're a decent player).
I more or less apply the above principles to 4betting over 3bets, except that if I think someone's 3bet range is KK/AA I will fold anything short of AA (this is a rare exploitative situation).
