Simple PF question

You open-raise to 16 in a $400 game with a small suited-connector or 1-gapper.

Known donk min-raises out of the blinds.

Assume that this is AA or KK 100% of the time.

His MO will be pot-sized bets on any flop, turn & river unless he has KK & an A flops in which case he probably bets, then checks calls small or check folds if you bet big.

Folded back to you - how short do you / him have to be to fold this PF?

How does your answer change if he’s button not blind?
