1: I think this is ok. KJ and QQ are 5 combos, AA and AK are 6. You're gonna face a cap if behind (but sometimes when ahead too) . I do think people usually will pump AK on that flop though. If you 3bet MP will often cap with hands that are both better and worse than yours so the overlay from tight button is not guarenteed.

2: I raise river and call a 3bet. I think your'e gonna see AJ/AQ/AK/99 a good amount here

3: I really don't like the turn checkraise attempt. 3bet the flop. Those opponents are exactly the type to check through with pair + draw or even a top pair now that it is headsup.
