BlackJack: What is the difference between single and multi-deck?

            BlackJack is indeed the internet’s most popular card game but why so many variations? Single deck blackjack is very friendly to the online gambler and is not played much offshore. It has gotten this user friendly reputation because it deals with no more than the standard 52 cards. There are less cards than the other popular 8 deck blackjack variety therefore making counting cards easier. Serious card counters keep a tally on all the cards dealt out and they up their bets at optimal times when the deal is in their favor. 
            This much can be said about the difference between multi-deck and single-deck blackjack, that single deck blackjack games have more blackjacks than do their multideck counterparts. Gamblers who enjoy the ability to double down naturally prefer the single deck blackjack games. The downside of this is that the dealer also gets more blackjacks. Since blackjacks pay 3:2 its seems worth the extra risk.
Basic strategy in single-hand blackjack says to always double down on 11 against anything the dealer is showing instead of doubling against two through 10 only.
