I came up with $20 on the average at an 80% rate. From as low as 66% when the dealers first card is an ace to 93% when he has a 6.

The trickiest part was to factor in pushes when the dealer gets a black jack at the same time I do.

Do my calculations feel about right or am I a little strong on my end?

Quote:BuckyMy local casino has a promotion each month that players get a free ace coupon that can be used up to $25. You can try again on a push. So, I used the blackjack calculator to see if I could get an expected return for my 25 bucks,

Is the free ace your first card? Can you use the free ace after you have been dealt one card? Can you use the free ace after you have been dealt two cards as a double down card? Etc....

I know it’s $25 but Grosjean has an article about the optimal kelly bet size and it’s just over 42% of your bankroll, at which point he extends the article to 14 pages in only a way he can by speaking in math for about 10 pages of obscure situational basic strategy changes based on the massive bet size.

The second part would seem to make it much easier.

This site suggests 50%.

Play it for $25 (not less); a CSM or fresh shuffle is modestly preferable.

Quote:BuckyThanks, I will look for it. The promo must be an ice breaker to get a few players to try a little black jack?

Of course. It is worth around $12 to you. They are guessing that on average you will lose more than that $12 in subsequent bets. It’s not enough to get anyone to go to the casino that wasn’t going, but if you were going anyway take the free $$.
