Hi,

Was wondering what the increase in player edge (decrease in house edge) for the type of play below would be:

The play is for 'Split or Surrender' and you get 80% of your bet back if you surrender

--------------------------------

Game Rules (General):

Decks: 8
Soft 17: Stand
Double after Split: Yes
Splits: Split any pair once
Can Hit split Aces: no
Surrender: Yes, (includes Early Surrender Against a dealer 10)
Hole Card: no^^^

^^^ Even though there is no hole card, the game is still a good one because, "If a player doubles down or split pairs against an eventual dealer blackjack, the additional bet will be refunded back to the player's account.... "

The game's house edge is about - 0.25% (not including any 'cash-back' bonuses, see end of this post)

----------------------------------

'Split/Surrender' Rules:

1. If you surrender, 80% of bet returned to player (in other words an EV of - 0.20, if you surrender)
2. Can't surrender any hands against a dealer Ace
3. Can only do 'normal early Surrender' against a dealer 10 (half of bet returned)
4. "IMPORTANT NOTE on SPLITTING PAIRS: When basic strategy does not indicate a pair to be split, the player will not have that option..."

Below is a list of 'split-able' hands that are allowed to be surrendered and should be in my opinion (if you can think of others please tell me, and say why you think so)

Pair 6's vs 2
Pair 8's vs 9

The pair of 6's vs a dealer 2 is only just worth surrendering, but the pair of 8's vs a dealer 9 is a really good play to surrender (under these rules).

----------------------------------

The reason why it is worth it for me to find out the extra player edge is because the game already has a slight 'initial' player edge of 0.05% , see below

The casino i play at has a slight player edge of about 0.05% at the start of the shoe on this game and their regular live blackjack game too, because they offer 'cash-back' of 0.3% (on TOTAL wagered, including doubles and splits).

Thanks for your time, and even though it will probably be very small increase in player edge, i would still like to know what it is.

Is this an online casino? Pretty generous if so, I would assume you might not get paid if you win.

Surrendering 6's vs 2 and 8's vs 9 will give you about 0.0095%. Of course, you should early surrender 8's vs 10, which is a basic strategy play. But, as you lose only 20% of your original bet, this will give you about 0.0533% additional edge for a total of 0.0628%.

Cash back expressed per hand is about 0.338%.

Your total edge should be:
-0.25+0.338+0.0628=0.1508%.

Taking into account the cut-card effect (about 0.02%) will give you a realistic edge of about 0.13%.

If surrendering 8s vs 10 is a regular early surrender (losing 50% of your stake) then your edge will drop to about 0.1% optimistically and 0.08% realistically.
