Taking advantage of four decks to the max

I've been doing alot of lying in bed thinking about blackjack and counting, heres what was going through my mind last night, I just need the mathematically inclined to assess my assessment.

Often times when i've been backcounting in a Casino with just one other player playing, the count will reach a nice high thats hard to resist wonging into, the shoe being close to finished with only one card on top of the cut card left. If there is only one other box being played, and you've been shuffle tracking the cut off slug and have already roughly estimated that a large portion of the cut off slug is 10/Ace rich, on top of that you've counted the majority of the shoe and have a high count, this taken in combination with your shuffle tracking and one more hand to be played puts you in a very powerful situation.

You could now open every other box not in play and also put your chips behind the one box being used by the other player. So lets say you max out all seven boxed, so a minimum of 8 x 2 cards will have to pulled from the remaining cards in the cut off slug which is only 1 deck thick. This combined with the potential for splitting tens, and other additional cards could potentially give you a situation where just over half of the remaining cards in the cut off slug are drawn. Wouldn't this now give you a massive advantage compared to what you'd usually be acustomed to?

uk rules S17, DOA, DAS, Split any pair, no peek, no surrender 4 decks. 75 -80% pen.

You are partially correct - being the very last round you should bet multiple hands - three hands is enough, however. And if its not the last round you should likely bet TWO.

When sizing multiple max-bet hands here is a rule of thump:

2hands: Your 1hand max bet amount + 50% - divided between 2hands.
3hands: Your 1hand max bet amount + 80% - divided between 3hands. zg

Ah the beloved 4-deck game!

They deal 4D in the UK? Where? That's enough to make me visit. I'd don my cowboy hat and my US flag lapel pin, daring any chav to meddle wi' me as I stroll down your streets into your casino.

In a situation like that what you are looking for is extra rounds. Better to play 2 rounds with one hand than 1 round with multi hands. (OK, maybe 1 round with 7 might excel 2 rounds with 1, but in US casinos you usually can't play more than 3 hands)

Part of the reason is that if the dealer gets the natural, you're equally buggered no matter how many hands you are playing.

Is there any more damaging info you can post about this game?:whip:

Casino operators read these sites, and your post for sure can do wide spread damage, even outside the UK.:mad:

This entire thread needs to be busted!

4D games in London

Hey guys,

anyone know any other 4 deck games in London other than at the casino that's been mentioned?

How much more advantageous is a 4D game than a 6D one? And what is the maths behind it?

I find that the TC gets *much* higher in the 6D game (75% pen). The highest RC I can remember from backcounting the 4D game is +14.
