AK

Donk/calldown.

I prefer donking also. There’s no guarantee villain will bet the turn.

Really need to know something about this guy's post flop tendencies for particularly good advice, but my default would be to attempt a check-raise and if not 3 bet, bet any river.
Balance for this with some check-raises when I have AQ with the ace of spades.

If I think the guy is bluffy or likes to go for very thin value in the river, I might try to check-raise again on a spade river, although I'm sure some would call that FPS.

"tagfish three bets in mp. He’s way too wide pre"

Do you mean LAG fish?

Lol, I didn't even notice that description. If I ever knew what TAGfish was supposed to mean I have long forgotten.
