double on split aces

i recently found a game whereby
1.players are allowed to double straightaway on splitting of aces ..how much is this worth.
2.also allowed to hit again on splitting of aces.
3.however player is allowed to buy insurance only after early surrender against ace,or after hitting(ie if the box is still alive ...is that too much of a disadvantage?

any figures on the advantages/disadvantades appreciated..
thanks

something related to question 1.

You have $10 up, receive 2 aces, you split them and before receiving anymore cards you can make the bet $20 on each ace ?

are you saying it's okay to double on your single card aces just after the split?

yes that is correct...what percentage is that worth?

yes thatis correct ,bomber...how much is that worth?

because it sounds like a version of Superfun...

Perhaps you might compare the rules of your game to Superfun21 as described on the Wizzard of Odds website.

Being able to draw to split aces is worth 0.19% ( http://www.wizardofodds.com/blackjack ).

However I can fnd nothing in relation to being able to double your bets before receiving the 2nd cards to split aces.

Its worth 0.1%.

When you get dealt AA, its a very profitable play, but you get AA about 1 in 200 hands.

table of Effect of Rules Variation on Basic Strategy is in Blackjack Attack 3, page 492. Post a question on rge21.com...

here's my partial guess of an answer...

from looking at Cacarulo's table in that book, I think for a 6D, S17, DAS game the ability to take multiple hits on split Aces vs hit once is a gain in edge of .241 for a split once for Aces game (.329 - .008).

I believe the option of doubling on an ace only would require some additional calculation using the tables in appendix of Professional Blackjack...

gain you get can be calculated for a 4deck game (which is probably close enough to approximate all games) using the data in Tables 7.1 and 7.2 of Blackjack Attack.

Table 7.1 gives the frequency of splitting Aces

and Table 7.2 gives the difference between hitting instead of doubling on a hard eleven when you hold that hand.

so if you multiply the values of the two tables together, you should get the answer.

Give thanks to D Schlesinger & his crew.

that is, have the 10's been removed leaving only the picture cards as the ten values in the deck?
