Extreme liberal blackjack rules

I played a game tonight with rules i have never seen. First it is a 4 deck game. S17. Double any 2 or 3 Cards (yes that is right) but wait there's more. Late surrender and surrender after double down. Split aa 4 times. Double after split. And 3 or more card 21 is automatic win. Dealer doesn't have a chance to make 21 for a push. Blackjack is 3 to 2. Anyone have any strategy for surrender after Double down.

Was dealt a 3 4 then a 4. I doubled and pulled a 10 for 21. I was paid on both bets right away and my cards cleared. Then dealer made 21. Crazy. I am not making this up.

Only thing I can think of is they are pulling 10s from the deck. I played 3 shoes and the count was positive 5 to 10 and more the whole time for 3 shoes.

Where?

The game you are referring to sounds a whole lot like Spanish 21. If there are no 10's in the deck, you have found the catch.
