Thirddan vs. Moozh...lines against 2+2er...

[thirddan]

from this weekend at the mirage...

6/12 with moozh and runa, but not sure if runa was at table yet...we are joking and having a good time, table is swinging between loose/passive and tight/passive...

Moozh is UTGish, I am to his left and act directly after him...

Moozh open-raises, I 3bet with KK, all others fold and we are heads up...

Flop: A K x
Moozh bets, I call...

Turn: y
Moozh bets, I raise, Moozh folds...

standard?

Same hand but I have AQ...
what is the most optimal line now, assuming preflop is the same?
moozh and I were talking and i don't know if we came to a consensus...What you think?
