There was about 70 players left, already ITM, with blinds 1500/3000. Villain is a tight player and the only hand I saw him show was QQ. My stack was around 75 000 entering this hand. I dont have the hand history here but anyways here it is.

I was dealt AQo in LP

EP raises to 6000.
All folds to me
I call 6000.
Button folds
SB calls 4500.
BB calls 3000.

Flop is dealt 7-3-7 rainbow
SB checks.
BB checks.
EP bets 3000.
I call 3000.
SB folds.
BB folds.

Turn is a jack
EP bets 25 000.
I fold.

I know I played this hand very passively but Im wondering whether or not to fold prefold/push preflop/push the flop etc.
