I have recently come across a game that offers 3:2 payments on split hand BJs. I have never seen this bonus granted in any real-life OR online game offered for real money or otherwise. The game is dealt out of a CSM. I am wondering how much this shifts the edge to the player, and even wonder if the game has a positive expectation.

The Wizard finds that the house edge is reduced by 0.21% by that special rule, so your game would not be positive EV for the player. See https://wizardofodds.com/games/blackjack/rule-variations/.

(I just now verified the Wizard's number using the infinite-deck model getting a reduction of 0.20% assuming no ace re-splitting. Also, I found that the player should not split 10s even if any resulting 10-As pay 3:2.)

Very interesting. I swear I致e been to that exact page a half-dozen times looking for this exact bonus, but must致e glossed over it, not expecting to find it. Interestingly enough, in conjunction with the rest of the rules (4 deck, S17, DAS, HSA, and Re-split to 2 hands), along with a 7-card Charlie bonus, brings the house edge very close, within >.01 of zero.

This is a little disappointing. I was hoping for a mathematically-sound excuse to split 10s, oh well.

Hi and welcome,

Does the casino that offers this game also offer any loyalty cards, rebates or other bonuses, because it may still be worth playing, if it does

Update (about 1135 pm):

Below are some links that may be helpful (I think you know the first link already)

Mathematically sound? No.

But as I致e said before, it has a high entertainment value.

I used to do it all the time at the old Sahara痴 $1 BJ table. And since BJ paid even money, I壇 double down.

The shock of the other players was worth every penny.

I'm not too well-versed at running OR fully interpreting results of software quite yet, however, plugging the ruleset from this game into Ken Smith's Combinatorial Analyzer shows a positive EV from splitting 10's, just not as much as standing, which I suppose takes away from the overall advantage.

If I could find an actual table with this bonus, this would be the first thing on my mind.
It beckons back to my first memory of playing blackjack, before I understood there was any strategy involved, and seeing the emotion of the entire table rise and fall with every incorrect play I made. The horror in one's eyes when I would hit a 12 vs a dealer 16 would make it seem I had intentionally set out to be the villain of the table, hell-bent on stealing the dealer's bust card. Now I get to revel in that same disdain when I make a deviation play.

Dion,

Unless you have next-card information, why would you hit your 12 when you know the dealer has 16?
