No-Bust 21st Century BJ (Ver 4.01) @ Ocean’s 11 Cardroom

Posted in blackjack by stephenhow on July 24, 2012

They’ve changed the No-Bust 21st Century BJ rules a few times at the Ocean’s 11 Cardroom in Oceanside, CA. They’re on something called Version 4.01, with the following rules:

blackjack pays 6:5
re-split pairs up to 3 times, including Aces
push on 3-card player busts of 23, 24, 25 when dealer busts with a higher total
late surrender on first 2 cards

I ran the rules in my blackjack analyzer, which calculates the EV at -1.34%. If that’s not crappy enough, they charge an additional ≥ 1% collection on every hand. I have no idea why they would create a worse game for the player, especially when they also face the house collection. I guess the corporation bank wasn’t making enough after paying for collection and employee costs.

The WoOs lists the player cost of 6:5 blackjacks at 1.39%, which is not overcome by the “No-Bust” rule. The strategy below looks a lot like regular blackjack, with some subtle exceptions that make sense for the alternate rules.

My analyzer now outputs HMTL, which is cut-and-paste here:

Aren’t the players allowed to bank? What is the edge for the banker after commission?

  Yes, the players are allowed to bank. You’ll have to pay collection as banker, so you’ll have a small edge whenever collection is 1% or less. For example, if there’s over $300 in action per hand, collection is < 1%. So your edge as banker can range from 0.1% and up. Of course players make lots of mistakes, so your edge goes up by another 0.5% or so.

I just updated the post to correct the “No-Bust” rule, where it only applies to 3-card player busts of 23, 24, and 25. Previously, I didn’t have the 3-card bust limitation. The house edge is now 1.34% _before_ collection. Yuck.
