The short answer is: No
While it might seem appealing to beat the casino from the comfort of your own home, the problem is that live dealers reshuffle the cards too frequently for you to get any confidence in your count.
For example, many online casinos instruct their dealers on an eight deck game to reshuffle after four decks have been dealt. This doesn’t provide a deep enough penetration into the shoe and to make things even more difficult, the speed of the games are generally quite slow making it virtually impossible to gain any advantage.
In summary, if you do choose to play with a live dealer online, enjoy it for the entertainment of socializing with beautiful dealers and fellow blackjack enthusiasts but don’t expect to apply card counting techniques to any effect.
