It would still work
You can surrender against a dealer face up, as long as it is early surrender. I am saying that you would surrender any hand other than a player BJ. This means that you would surrender a hard 20 against a dealer 6 up. Obviously not the EV maximizing decision, but it is better than taking the $50K, at no additional risk.
I agree about the maggots part. I could probably do that for $500K, though. Everybody has a price.
