And to give you a few numbers: there are 1326 starting hand combinations. 6 of them are AA. That are 0.45%. There is one combo of KK left. Makes 0.53%. There are 8 combos of AK. That makes 1.13%. PFR of 2.5 is more than AA, KK. His 3betting range might be smaller. But when he is playing so tight, he probably is willing to commit all of his chips preflop with most of those hands.

When villain reraises OP to $3, I think his range is somewhere around AA-QQ, AK (1.6%, btw). His reraise after villains minraise tells us basically nothing.
