Otherwise, the players at the table finish playing their hands. If the dealer has blackjack, all DB21 wagers lose. The player makes a DB21 wager before any cards are dealt. I am therefore pleased that the results of this advantage play analysis did not expose negligence on my part.
At the time I did this analysis (December, 2010), I was not routinely considering advantage play for games. My report would normally be confidential, but in this case the inventor, Peter Blaine, decided to post my report on his game’s website (now defunct), so here it is.
This one has a unique distinction: I was the mathematician who did the original mathematical analysis. DB21 is yet another blackjack side bet that pays if the dealer busts. At G2E (2013) this year I saw a side bet that seemed very familiar to me, Dealer Bust 21 (DB21), at the TCS John Huxley booth (as of August, 2016, DB21 is offered by AGS).
