Full Early Surrender Deviations

[fullearlysurrender]

A casino where I play has 6 decks and offers full early surrender, h17, no hole card peak, double any two cards, double after split, resplit up to four times (aa only once and you may hit), bj pays 3:2.

Calculators give me different edges for the player ranging from .15% to 2% and I wonder if anyone knows the exact player edge. At what TC would you start hitting 10v9 instead of doubling, surrender an 8 vs A, and surrender 13/12 vs t? What other major deviations would you consider for this game?

[DSchles]

I make the player BS edge 0.275. I'm assuming that the split aces can be hit but not doubled. If they can be doubled, add another 0.152, to make player edge 0.427.

Hit 10 vs. 9 at TC < -2. Surrender 8 vs. A at TC >=+10. Surrender 13 vs. T at TC >=+3. Surrender 12 vs. T at TC >=+8.

Is this a land casino? In the U.S.?

This is a land base casino in Colombia. Did you use an online calculator to arrive at that figure or some of your own? Also, at what TC would you surrender 15 vs 9 and 16 vs 8? Yes split aces may be hit

[fullearlysurrender]

Is there a TC or deck composition where BS edge would be negative and that happens more than 2.5% of the time with deck penetration of 1.5?

I get player edge ~= .1646%

My revised CA generates running count indexes based on a player hand (total or composition) and pen (cards remaining). The RC indexes at midshoe translated to true count virtually always is pretty much in agreement with reliable sources. In order to get a reasonable estimate of TC at midshoe for 6 decks the RC indexes need to be divided by 3 (decks).

So for HiLo:
index for doubling hard 10 v 9 ~>= -2
index for ES hard 8 v A ~>= 1
index for ES hard 13 v T ~>= 3
index for ES hard 12 v T ~>= 8

Count tags {1,-1,-1,-1,-1,-1,0,0,0,1} H17, D2, ENHC, HSA, NDASA, DAS
6 decks, pen = 156 cards remaining

BJA3, pp. 492-3.

Also, at what TC would you surrender 15 vs 9 and 16 vs 8?

Assuming Hi-Lo, TC >= +2 for the first and TC >= + 4 for the second.

Yes split aces may be hit

I know that; you said so! Asked if you could double.

Hi Don, was just curious as to the rational of surrender 12 v T at a much larger TC than 13 V T. In my mind, it's only one number difference.

Thanks

[DSchles]

"Hit 10 vs. 9 at TC < -2. Surrender 8 vs. A at TC >=+10. Surrender 13 vs. T at TC >=+3. Surrender 12 vs. T at TC >=+8."

Sorry for the typo. Don't know how the zero got in there.

Can't really think that way. The numbers are what they are.

"I get player edge ~= .1646%"

I used BJA3, pp. 492-3. Can you show me your breakdown to see where we may differ.

6D H17 = -0.761. DAS = + 0.144. Split aces once with multiple hits = +0.177. ES = +0.715. Total: +0.275.

For 6D, H17, DOA, DAS, SPA1, SPL3, ES ==> Ev = 0.098432%, and if HSA, Ev = 0.275664%.

Are you sure it's not ENHC?

I just input the rule options into my CA at once and click 'Compute'. I don't parse the value of each rule deviation individually.

Your numbers are correct for ENHC (I get 0.167306%). But this is NHC.
