Hi everyone!

Iím a newbie to the site, but so far find the material brilliant, especially the Wizardís tools. I have a few questions I was hoping to get help with about playing European blackjack with the following rules:

* 6 decks with CSM
* BJ pays 3:2
* No hole card (player loses total bet, including after doubling or splitting, if dealer has blackjack)
* S17
* RSA/split aces receive 1 card only
* 21 after splitting aces not BJ
* Double only on 9, 10 or 11
* DAS
* No surrender

The interesting twist is that there is a single joker added to the shoe. The joker has no value itself, but if a player ends up being dealt one, the regular payout is doubled.

If a hand with a joker is split, the player decides which of the two hands the joker will be assigned to before additional cards are dealt.

I am familiar with the Wizardís standard basic strategy chart for European BJ, but was wondering if having a joker changes the optimal play, particularly in the following situations:

* 11 v 10 or A (should double?)
* Split Aís v A?
* Split 8ís v 10 or A?

There is also an unusual side bet that I have not found discussed anywhere. If a playerís first card matches the dealerís first card (the suit does not matter) and the player wins or pushes the hand, the player wins 22 times his bet. If at the same time the player also receives a joker as one of his first two cards, the payout is 400 times. What is the house edge for this side bet?

Thanks in advance!

Something seems amiss in that side bet. 22 times the bet if dealer has 7 and I have 7? That is about 13:1 odds for a payout of 22Xs? Joker is 1 in 312 cards but boosts that to 400Xs?

Where is this casino? Either I am missing the math big time or I need to make that table my office.

22-1 sounds high.

I believe in the Match The Dealer side bet, an unsuited match only pays 4-1. The difference being, with that bet you donít have to win or push the hand.

First you have to match, then you have to win or push.
The race is not always to the swift, nor the battle to the strong; but that is the way to bet.

But youíre not paying anything extra to get this bonus. Itís not like a side bet where you have to risk something.

Just rough estimate, if I match the dealer 1 out of 13 times, and I win or push half of those, then about 4% of the time Iím getting paid 22x my bet.

I don't think it's high. But it's not too bad for a sidebet, either, IMO.

Summarized Net Win in Blackjack
EVENT PROBABILITY
Win 42.43%
Push 8.48%
Loss 49.09%

Win or push 50.91%

Chance of matching rank 1/13 or 7.69%

So you can expect to win this bet 3.92% of the time. True odds would pay 25.54:1 . They're paying 22:1.

I'm not counting the Joker because it's a bit beyond my computational powers at the moment. So not offering a HE. I would swag the Joker ( 1 card in 313) paying 400:1 might add .5% to the player at most - seems like a very rare event.
If the House lost every hand, they wouldn't deal the game.

OP says itís a side bet. The joker thing is the non side bet.

I knew I missed something there.

It still seems more fin than that in-between bet.

Great, thanks for the helpful analysis.

As far as basic strategy, I take it that having the joker with the double payout would not change the optimal double/split decision, right?
