House edge reductions obtainable with backbetting

[camicio]

According to my calculations the house edge can be reduced with a front player who makes bad choices if they can help the backbetter at most of
0.166142433% if playing 6d s17 das doa, Player may resplit to four hands except aces, No drawing to split aces
0.169277055% if playing 6d s17 das doa, Player may resplit to four hands except aces, No drawing to split aces
0.166778994% if playing 8d s17 das doa, Player may resplit to four hands except aces, No drawing to split aces
0.148650164% if playing 1d s17 das doa, Player may resplit to four hands except aces, No drawing to split aces
0.156761147% if playing 6d s17 no das doa, Player may resplit to four hands except aces, No drawing to split aces

Even if the backbetter bets only half of what the front player bets, the house edge can already be reduced of 0.071704606% if the right decisions are taken

I don't know where how to get the expected values for each action for the european no hole card rule, so I can't say of how much the edge could be reduced

http://camicio.altervista.org/_alter...backbetter.zip to download an excel file that shows which splits the front player should make and the backbetter shouldn't in function of the front player bet/backbetter bet ratio (I took the values from http://wizardofodds.com/blackjack/appendix9.html, and I know I'm not good at all at making clear what I'm doing and why, sorry)

When used properly this technique can reduce the house edge by 0.2%. The complete strategy is in Wong's "Basic Blackjack." Here's a link to an old discussion about it:

yeah i was looking at this a while ago to and got 0.2%.

i use this strategy some times. but to get the full 0.2% you need to be betting like $200 on the back, and $5 on the front...
