Single Deck multi hand strat

[DSchles]

don, your book mentions griffin's book Theory of Blackjack, referring to tables on page 70 and 28. thats one of the few blackjack books that i do not own. could you help me here and post the tables?

in BJA3, you mention that the average number of cards dealt per hand is 2.7. would it be even better, if spots 1 and 2 were betting $1 and spot 3 was betting anywhere from $100-300, to have spots 1 and 2 always take as many cards as they can? for example, spot 1 is dealt 2,2 vs dealer 10. spot 1 splits and takes as many cards as possible, even if it makes him bust. now, spot 2 has A4 v 6 and just hits in hopes to hit at least twice, giving spot 3 even more information to play his hand with the max bet out. or is this giving up too much ev for spots 1 and 2, even if they are betting far less than spot 3? you could easily ramp up that average cards dealt from 2.7 to maybe even as high as 4. (i dont know that math, but obviously its much higher since you can split every 20 and play like a maniac to burn through more cards)

The way to answer the question is to compare the the e.v. from doing the second-best thing for each of the first two hands (see BJA3 charts, p. 98) to the correct play, to see how much you're giving up. But with $1 bets, I'd say, it's a moot point. Then, you see how much extra gain you get (Griffin's tables) from seeing those extra hit cards, and you compare to see if the extra gain for the $100 bet surpasses the loss from the $1 bets. I'm sure it would.

WARNING on Theory of Blackjack.
TOB was printed in 1979, 1981, 1986 and 1988
The numbers Don is referring are in the latest editions. If you refer to the 1979 edition, you will note that the "Strategy Gain (no insurance)" differs from those more recent. In fact, the were reviewed and slightly upgraded by Griffin. The numbers referring to "Insurance Gain" haven't changed.

Will try to save work for Don here!
From TOB, 1988 edition:
Unseen cards / Insurance Gain / Strategy Gain
10 / 0.51% / 4.22%
15 / 0.36% / 2.68%
20 / 0.27% / 1.81%
25 / 0.21% / 1.23%
30 / 0.15% / 0.83%
35 / 0.11% / 0.53%
40 / 0.07% / 0.31%
45 / 0.03% / 0.15%

what does his final column "bet gain" refer to?

From Griffin, it means "betting one extra unit when the deck is favorable for basic strategy".

Very subtle and highly informative posts here.

It was Griffin refinement!

So irrelevant when its a fresh shuffle every hand.

So with 45 unkown cards, there is +ev right away even for hand #1, so flat betting all 3 hands would be +ev on every hand, with ev getting progressively higher on hands 2 and 3

You never answered my post. Is this some sort of video blackjack machine or a live table?

Online, but live table would be even better

[blueman]

Is this some sort of video blackjack machine? Beware that many of these video games deal each hand from a separate deck. Meaning that even though this is a single deck game, you might see the 7 of clubs in 2 different hands.

confirmed that its 3 hands from the same single deck, can never receive the same card on 2 separate hands in the same round

Good.
