This is a live 2/2 game with a $5 utg straddle. Effective stacks: $1000 so we're pretty deep. The game is full ring, has been playing loose passive preflop and tighter postflop.
Villain is the only player at the table whose game hero respects. Villain and hero have EXTENSIVE history (we've been playing PLO together for 5+ years) and villain is a very good TAG. He has a WSOP PLO final table under his belt. He is in the hijack.
Hero is the button with A

3 players call the straddle. Villain raises to $25. Hero 3-bets to $95. It folds around to villain who instantly makes it $250 to go.
Villain's 4-betting range, especially against hero, is EXTREMELY narrow. It basically consists of the case aces, double suited KK with Broadway sidecards and perfect double suited rundowns. In the whole time we've played with villain, we've seen him 4-bet/fold in spots like this precisely never, so if we ship we're definitely getting called.
My question is: how deep do we have to be to just flat the 4-bet and take a flop with a decent AA hand in position? Or are we just getting it in pre always and just run the cards out and see who wins?
Thanks in advance for not trolling me; I know the answer to this is probably pretty obv.
