Among modern players, the opinion is very common, according to which, counting cards, you can win very serious money in blackjack. But, as practice shows, counting cards will not allow you to get any advantage over the casino.
Go to the Sutie
We will not pour water or distracted on third-party themes, we will immediately move on to the essence. Suppose we will take as a basis the insurance rate that will be made against the dealer who has an ace and there is a possibility of natural blackjack (combination 21). The insurance rate is paid in the amount of 2 to 1, if the closed card brings a dealer of 10 eyes and loses if there is any other card that is not a ame.
So, in itself, the word “insurance” introduces inexperienced error players, because the insurance rate, in its essence, does not guarantee anything. You just make an extra bet on the game, which, plus everything, offers you not the best chances.
Yes, professionals in some cases make insurance rates – this happens in cases where there are many non-played cards in 10 points in the box for the deck. In such a situation, the likelihood is increasing that the dealer’s closed card is worth ten eyes and makes the insurance rate beneficial for the player, but not for the casino.
On the coefficients
Let’s imagine that you play blackjack with one deck – as a result, as a result of the first distribution you get a pair of 10, and the dealer, in turn, gets ace. Dealer offers player insurance rate. We know that in the deck there are 14 cards worth 10 points and 30 cards worth up to 10 and three aces. A little mathematics – the chance that the dealer’s card is closed for 10 points is 14 to 33 or 1 to 2.357.
Thus, the proposed coefficients are much worse than paying 1 to 2, which is offered for the victory in the insurance rate. The advantage of casino is obvious and from the insurance rate should be abstained.
The point of making the insurance rate has only if the ratio of aces with 9-point cards and 10-point cards, which remained in the game less than 1 to 2.
Without card counting
It is known that today there is a way to assess the ratio of decades and a common deck, which shows the validity of the insurance rate without counting the cards. Suppose 6 players for playing blackjack use 8 decks. The game is conducted within some time and you can appreciate that about 5 decks have already come out of the game, while 3 decks still remain in the game.
The next game round begins. You see 12 player cards, as well as an open dealer map. Suppose that the 10-point card did not get anyone, and the dealer got ace and offers you an insurance rate.
Suppose 3 decks are involved in the game – 156 cards. 10-point cards of them: 4x4x3 = 48 pieces. If after the distribution is complete, no one has a card worth 10 points, you can subtract more 13 cards. The dealer thus remains 156-13 = 143 cards. As we thought before, in 3 decks 48 cards worth 10 points. Other cards – 95 pieces.
In this case, the chance that the dealer has a card for 10 eyes, is 48 to 95 or 1 to 1.98. Since the payment of the insurance rate is 1 to 2, the chances of 1 to 1.98 give us an advantage of 0.7 cents for every dollar bet.
Another example
Suppose 6 players and 2 decks participate in the game – on the hands of the dealer there are 104 cards. Distribution was performed, following which none of the players has 10-point cards, the dealer receives ace. It turns out that after distribution in the game there were 91 cards.
Shuz will consist of 32 10 glasses cards. Thus, the number of other cards in the game – 59 pieces. The chance that the dealer has a closed card, brings him 10 points 32 to 59 or 1 to 1.84. Since the chances are lower than the payment on the insurance rate, such a development of events gives a player an advantage of 5.5 cents from each dollar.
If there are 2 decks in the shower, the player in any case remains the advantage. And if after distribution there will be one 10-point card, the advantage will be 2.2 cents for each dollar bet.
note
Most importantly, what to do after our article is not to succumb to the influence of emotions and not confuse a positive wait (this is when you have a good chance of winning) with a guaranteed win.
Ideal conditions for insurance rates practically does not exist. Most often when in the hands of the dealer remains less than 3 decks, the game begins again.
Important moment – if you overestimate or underestimate the number of decks in the shower, then miss your chances of winning you just like never.
