I was reading through some of your past Ask the Wizard columns and saw your calculation of the probability of a string of losses in the August 4, Column.

My question though is what does that really mean? Is it that when I sit down at the table, 1 out of my next playing sessions I can expect to have an 8 hand losing streak? Or does it mean that on any given loss it is a 1 in chance that it was the first of 8 losses coming my way?

Your expected loss of this play is 0. The betting system will not affect the expected loss, but will affect the volatility. Does losing a hand at blackjack increase the probability that the composition of the deck is in your favor? More specifically, is your expected return on one hand ever positive after a given net loss since the last shuffle? The answer is emphatically yes! In fact, betting strategy is critical for anyone who wants to be a profitable blackjack player.

Yet, if you have 16 points, the strategy indicates you should surrender if the dealer is showing 10 or more points.

Like all blackjack strategies, this also adjusts for the number of decks in use. Another advanced play that can affect blackjack strategy is buying of insurance to protect yourself against the dealer hitting When the dealer is showing an Ace as the up card, you can lay up to half your original wager on whether or not the dealer has a point card in the hole. If the dealer does have blackjack, then you get paid 2 to 1 on your insurance wager.

A lot of players of 21 will choose to buy insurance if they get a hand worth 19 or 20 points off the deal, but the dealer is showing an ace. They view buying insurance as a way to protect a strong hand, but you still could lose both wagers, or wind up with a push and a loss.

The only time it is useful is to card counters who are deep into counting off multiple decks, a situation that is not accounted for by strategy cards.

Card-counting is a strategy that makes it possible to beat certain blackjack games if the conditions are right. Movies often inaccurately portray this as memorizing every card that has already come out of the deck. There are actually a number of different count techniques, but the gist of all of them is to keep a count of how many high-value, middle-value and low-value cards have already come out. When lots of high-value cards are still in the deck, the player has a statistical advantage over the dealer, since their probability of hitting a natural blackjack is increased which pays out more than a standard winning hand.

They are also mathematically more likely to be successful when doubling down, and the dealer is more likely to bust when being forced to hit on a 12 or higher. The most basic counting technique has players add one unit to the count for when a low card comes out, and subtract one unit when a high card 10 and face cards comes out.

The 7 to 9 cards are considered neutral value and not tracked. As the count value gets higher, the player has more of an advantage and bets higher. There are more complicated counting techniques that are considered more accurate and profitable, but there is an increasing trade-off between tracking the count and continuing to play with the perfect strategy needed to make the system work.

Even with perfect play, it takes a large bankroll and sometimes many hours of play to see a significant profit from card counting. Unfortunately, card counting is completely useless at video blackjack games such as the ones seen on Game King machines , as well as the similar online counterparts. Live video streaming blackjack creates an interesting possibility for card counting. Players can use strategy cards without detection to take some of the mental workload off, focusing solely on their count.

They may also be able to use apps and software that aid in counting, though apps that interact directly with the casino software may be detected and get the player kicked out.

The absolute biggest player-unfriendly rule is when the house has the dealer win any sort of push. This can swing the house edge from 3. Short pays increase the house advantage by anywhere from 0.

Individually these rules each give the dealer about a fifth of a percent of an advantage, and all three together give the dealer about a full half of a percent. Certain other rules have a negative impact, like not allowing the player to split beyond three hands, but they generally have a trivial impact on the house advantage in isolation.

There are no government or state laws prohibiting card counting, including at online games. Some regions actually have laws preventing casinos from barring card counters, like Atlantic City and Mississippi. However, outside of these odd exceptions, casinos are largely free to set the terms of their games and rules about player conduct. This means they are allowed to bar players they suspect of card counting.

One might get in trouble for suspected card counting at a live video streaming blackjack game, however. Casinos usually track card counters by their changes in bet size, especially as the shoe runs out. This means they need to monitor an extended period of play to determine if someone is actually counting cards. Once a card counter is identified and asked to leave a casino, however, they can expect that information to be shared with some amount of other casinos and to find themselves unwelcome at their blackjack games even if they have never played there before.

You need to keep an eye on the chip piles of other players relative to your own, and also be mindful of how far along you are in the tournament to determine the best bet amount for any given hand. Some general tips are to match the biggest bettor when you are leading in chips, bet opposite of the leader when you are trailing in the chip count, and hold back one chip when everyone else goes all-in on the final hand.

This technique involves observing a table and keeping count without actually playing, then jumping in only when conditions are favorable. Some tables forbid new players from joining in the middle of a shoe specifically because of this technique. This practice is more common at smaller casinos that consistently have more demand for blackjack action than they do available table space.

Online casinos rarely bother with this as a theoretically infinite amount of players can be accommodated at any time.
