Hi,

I have a question regarding how deep a cut card is set (penetration) and its effect on a 6 deck BJ game with the following rules:

Number of decks of cards used: 6
Dealer hits or stands on a soft 17: Stands
Player can double after a split: Yes
Player can double on: Any first two cards
Player can resplit to: 4 hands
Player can resplit aces: Yes
Player can hit split aces: No
Player loses only original bet against dealer BJ: Yes
Surrender rule: Late
Blackjack pays: 3 to 2

These rules give the casino an advantage of .28507%

If the casino sets the cut card at different depths, (a) 1 deck (b) 1.5 decks (c) 2 decks (d) 2.5 decks (3) decks, how does that effect the casino's advantage?

For example if the casino sets the cut card at 1.5 decks normally, but then cuts off half the shoe at 3 decks in a 6 deck shoe will the casino's advantage increase?

And if there is an effect- is the relationship linear? Is each half deck worth a certain percentage gain for the casino?

Thanks for the answer in advance!

Not directly.

They'll be spending more time changing cards in and out of the shuffler (or time shuffling), so they'll deal fewer rounds per hour.

House edge on each round will be the same, but they'll play fewer of them, so they'll end up taking less money.
May the cards fall in your favor.

Agreed.
It's not whether you win or lose; it's whether or not you had a good bet.

What is the effect of moving the cut card up for the casino?

If a casino suspects an AP or count counter often the casino cuts half the decks off in the shoe. Why does
the casino move up the cut card if it doesnt effect the game?

With more unseen cards, the counter might find it harder to identify a situation of advantage.

Shuffling with more unseen cards remaining will decrease hands per hour. This affects both the card counter and the house.

I'm sure I've read a few articles where consultants point out that the early shuffle does more harm than good for the casino, but I can't find any to link at the moment.
May the cards fall in your favor.

The early cut card keeps the count closer to zero more of the time.
