Are there any

books that explain the different shuffles a casino uses?
Especially for Double Deck.

I would forget about tracking DD unless you find a game where they do a single riffle and restack (1RR) There are some good books on the subject, but it really boils down to you keeping your eye on the birdie.

You'll have to look, watch it carefully, map it out on paper in a corner, go back check to see if it's still the same.
Or use your imagination on all possible shuffles.
No need to get a book on it, it can vary. Just watch!

One of the casinos I play at changes cards about every two hours. It seems like the first hour after the new cards are put into play the cards come out Large, Small. So you have a lot of stiff hands. The second hour, it seems, the cards start to fall in a better pattern. So I don't think that I'm trying to shuffle track. Just trying to get some information on the different ways a casino shuffles, and does it effect the way the cards come out, or am I just having a bad run every time they bring out a fresh decks.

Thanks for you input

"It seems like the first hour after the new cards are put into play the cards come out Large, Small. So you have a lot of stiff hands."
-Someone's not washing the cards thoroughly before beginning their shuffle routine! While I have run across this at a few shoe games in the past, and was able to exploit it, I have never seen it as exploitable at 2D games, though "Ace locator" fans may disagree.
@^!
At the shoe games where it happened, I would wait until I saw some "evidence" that the section I was interested in was in fact coming out, (A common trick a lot of trackers do,) and then I'd bet up. Slugs in shoes are large enough to do that with. When it was time for the low end of the spectrum, I'd either bet small or take a bathroom break. In essence I was still slug tracking, just doing it in a different manner.
@^!
Its important to note that even within 6D shoe game (312 cards) the discrepancy (I'll refrain from using the term "bias", for obvious reasons!) in the randomness only lasted maybe 2 shoes at the most before they just became too random to rely on. Generally, it was more like 1 shoe of reliability. But what a nice shoe that would be!
@^D
Unfortunately, in regards to your 2D inquiry, off the top of my head, I think it would be real hard to exploit this. (Again, "Ace locator" folks may disagree.)
The smaller number of cards are the problem.
@^!
If you were to find someone who improperly washes new cards before shuffling, retaining a reliably predictable slug within 104 cards would be even harder than a shoe game, provided that the house shuffle is adequate and the dealer does it properly.
@^(
But lets say you find all of the "necessary ingredients": new cards coming out, poor washing, and an inadequately executed shuffle. You still run into the "evidence" problem. By the time you see enough adequate evidence that the slug is coming out, it would already be over.
Smaller number of cards = smaller slugs.
In this case, I suspect historical data will do you little good.
@^!
However, mine is merely a drop in the vast sea of BJ opinions...
Question:
"The second hour, it seems, the cards start to fall in a better pattern.."
-Exactly what constitutes "a better pattern" to you?
Take care,

a better pattern is when the TC is +7 and a face comes up on my double down and not a duce. Or when large and small cards start to clump together. I know cards do not always fall the way the count or I think they should, but it seems like this happens EVERY time I play at this casino. The wash is not what I would call a long wash, what ever that is, and they use a quick shuffle, or not too many passes. Next time there I plan on writing down how they shuffle and try it at home. I may be making a mountain out of a molehill, but it bugs the hell out of me why this pattern seems to come up every time I play there.
Cards come out Large-Small with the dealer showing a non stiff hand, no matter how many players are at the table, so maybe that is a good wash and shuffle but it sure sucks when your playing the game for the first hour.

Thanks Again

" I know cards do not always fall the way the count or I think they should, but it seems like this happens EVERY time I play at this casino.
-I think probably the operative part of that sentence is "seems".
@^)
I understand what you are saying though.
@^!
"The wash is not what I would call a long wash, what ever that is,.."
-With only 2 decks, if the wash the 2 decks together, it doesn't take very long to quickly break up those original senquetial groupings.
"and they use a quick shuffle, or not too many passes."
"Next time there I plan on writing down how they shuffle and try it at home."
-A statement like that makes me think you may eventually become a tracker! While I don't want to discourage anyone with an inquisitive mind, as I stated earlier I think you may be wasting your energy with trying to track a 2D game. However, if doing so serves as a "back door" to get you into tracking, then more power to it.
Good Luck,
