1. Blackjack Betting Strategies are quite popular, especially since the game has been featured in hit movies like Rain Man, 21 and The Hangover. No matter what the game, there is one universal rule; if the casino spreads the game, someone has developed the “perfect” betting strategy. Roulette strategies are perhaps the most prominent as roulette strategies and systems have been offered for.
  2. Lesson 22 – Beating the Double-Deck Game – Part 2. In Part 1 (lesson 21), I tried to demonstrate that the real key to winning at this game is finding one where the casino deals more than 50% into the decks before shuffling.Admittedly, you can make a few $$$ in a game where only one deck of the two is dealt, but it’s certainly not easy and your earnings really are limited.

Single deck blackjack has often been looked at as the holy grail of the game because it offers players the best chance to win profits. In fact, the house edge is just 0.15% when players stick to blackjack games with a single deck. With this being the case, you’d think that single deck blackjack is the greatest thing ever. However, there are actually some disadvantages to the subject as well, which is covered below along with single deck blackjack advantages.

Jan 23, 2018  Professional blackjack player, DarkStar, compares double-deck pitch to the typical 6 deck shoe game. Which one to play is up to you but both have advantages and disadvantages. There are many other.

Advantages

The obvious advantage to playing single deck blackjack is just as we stated before in that you’re getting the absolute lowest house edge. Facing a 0.15% house edge puts you on nearly a level playing field with the casino, and makes your chance of profiting seem like a coin flip. Of course, to take advantage of the low casino edge, make sure that you understand good basic blackjack strategy first – otherwise, it doesn’t really matter how many decks you’re dealing with.

One more big advantage of single deck blackjack comes for card counters. Usually, card counters these days are dealing with six and eight deck shoes, which means they have to wait longer for favorable counts. But with single deck blackjack, card counters don’t have to wait nearly as long to get a favorable count, thus letting them bet big much sooner.

Disadvantages

Based on the aforementioned advantages, you wouldn’t think there’d be much downside to single deck blackjack. But the problem is that casinos often advertise single deck games, yet offer unfavorable rules to increase the house edge. And what’s bad about this is that the house edge can actually end up being higher than with six or eight deck blackjack.

In the worst case scenario, casinos will only make 6:5 blackjack payouts instead of 3:2 payouts. This one rule alone will bring the house edge from 0.15% all the way up to 1.45%. Considering the fact that you can still keep the house edge at around 0.5% with both six and eight deck blackjack, it’s sometimes not even worth the effort to search for single deck games. Casinos might put other unfavorable rules in the single deck games too, so watch out for this.

Another disadvantage to single deck blackjack is that you’re very unlikely to earn many comps with this version of the game. After all, if it’s true single deck blackjack you’re playing, the casino won’t make much money off you in the long-term. That said, they aren’t going to be generous with comps either.

Hello BJ players,
I wonder what's the effect of card counting (let's the say the best way of counting which is Wonging in my opinion) when the casino uses 8 decks and a cutting card on 50-60% of the deck.
Let's say the other rules are normal. Dealer stands on S17, BJ pays 3:2, so a normal house edge around 0,6 or 0,7%.
I think it is almost impossible to gain an advantage because of the 8 decks. But when it mighte be possible, it can be done on some online casino's where you can just sit without playing. Just back counting and wait till the deck is more hot (with aces and 10's).
What are other peoples experiences?

Under the conditions you describe, I would say that the game is not worth counting and should be avoided. There are some 8 deck games that can be beaten and some that can be a tad better than a comparable 6 deck game. The important thing is good penetration and you just don't have it here. With the house edge you give, there's obviously no surrender which makes matters worse.
If you absolutely must play this game, a proper bankroll is crucial as well as aggressive Wonging and a betting spread of at least 1-20 units. Wong in at TC +2 and Wong out at 0.
You'll have to be very patient, as a very large amount of your time will be spent casing tables. I hope this isn't the only game you have access to because it's not great.

Thank you for your asnwer.
I don't play the much online (playing in a real casino gives me much more fun) because blackjack in an online/live casino is terrible slow.
But when I do, I try to count but I wanted to know what the effect was because of the 8-deck and early cutting card.
And even when I count, sometimes I looks like the cards are 'clumped' together. What I mean is when the dealer draws small cards over and over again she keeps drawing small cards.
And for example, a dealer started with a new shoe. And out of the first 60 cards where 15 aces or some, all clumped together (maybe the shuffle is terrible).
It's on Unibet. But thanks and good to know you can't really make a long-term profit out there.

The penetration is pretty horrible and the game should be avoided based off of that for 8 decks. If you indeed have 'standard rules' (DAS, DA2, S17, 3-2 BJ) I believe that game is about 0.55%.
You can absolutely gain an advantage in this game (assuming you find a dealer with better penetration), regardless of the 8 decks. The lower number of decks yes the slightly better odds you get, but the math works the same. Each true count will increase you by ~.5%. Thus, in the game you're describing you can have an advantage at TC +2 and above. With wonging I don't see why this game wouldn't be beatable (if you can find a table with much better penetration). Again, this is for much better penetration (75%+). If you absolutely can't find anything above 50-60% PEN, I wouldn't play.

The problem with the 8 decks is not so much that the HE off the top is higher (that is minor) but that the TC is less volatile, so profitable situations come up less frequently.

Correct me if I'm wrong, and I do understand why playing with less decks is more advantageous, but for any number of decks isn't the following true?Blackjack

Where did you get those numbers from? That can't possibly be right.

First, the frequency depends on penetration. The deeper you deal, the more frequently the higher counts will come out.
Second, it has to depend on the number of decks. Think about it: If you are playing double deck, the true count could easily jump to +2 after the first hand. That's more or less impossible at an 8 deck game. The TC will jump around a lot quicker with fewer decks because the denominator is smaller (that's the same reason that you need deeper penetration to get the higher counts out; the denominator drops as you deal deeper).

Again, I understand why this makes sense with fewer decks. But how many times in a DD game have you had a TC +3 for 4-5 deals? That's quite possible in a 6 or 8 deck game where as it's not as likely in a DD game. So overall they should average out and you should have an equal number of advantageous bets, with yes, lower number of decks being more short term 'volatile' to the TC.
