It seemed to place a higher priority on staying in the game (not hitting on various soft hands) so as not to lose 3 bets at once by going over. It seemed to us that this changed the strategies for blackjack somewhat. Essentially, you are playing the same hand 2-3x vs the same dealer 'face-up card'. The dealer resolves the first bet normally, then keeps the original face-up card and starts all over again, resolving the 2nd bet, and then the 3rd. You hit/stand/double/split as in normal AC blackjack. You are dealt your hand and the dealer is dealt one card (face up).
Some friends and I were in AC last weekend at the Claridge, where we spent the evening playing something called 'Multiple Action Blackjack.' If you do not know about it, basically, you can bet either 2 or 3 times.
