AT top pair...flop action?

[drdaman]

Playing a 9 handed $25-max NL game online.
Just sat down, no reads on villain. Board is rainbow

HERO (HI-JACK): $24.75
CO: $17.00

Pre-Flop: A T dealt to Hero
Hero raises to $1, CO raises $3 to $3, Hero calls $2

Flop: ($6.10) A Q 4 (2 Players)

What do you suggest to do on the flop?
actual action in white



<font color="white">

HERO checks, CO bets $3, HERO raises to $8, CO raises to $14 and is all-in
HERO shows AT
CO shows AA

Turn: ($32.10) 2 (2 Players)

River: ($32.10) 2 (2 Players)

fold preflop, you are out of position with a dominated hand

fold the flop to serious action, villain really clearly has an overpair here
