I once dealt a player 20 straight winning hands at a blackjack table. He was the only player at the table. I dealt out of a eight deck shuffle machine. Dealer hits on a soft 17, split any pair and double any two cards. What are the odds?

Do you know if he made any mistakes off the top of your head. Maybe do anything odd such as stand when they weren’t supposed to kind of thing?

Don't recall anything out of the ordinary. A streak like that makes one suspicious, but there were no issues.

So did he have a bet spread? Did he go from $25 to $250, with or without a count?

It looks like the odds of 20 consecutive wins in a row would be astronomical. Obviously certain assumptions would have to be made. But I think if we just assume basic strategy we could base the odds on that and get a meaningful answer.

$50 per hand. Total winnings = $1200.

Agree. I just don't know the math.

If we ignore pushes as no-action, the odds of winning 20 hands of black jack in a row is fairly close to 0.47^20, or about 1 in 3.5 million.

But you asked about the chance of dealing that to a player. That depends on how long your career as a dealer is, as well as the behavior of the players, and how often you have to take breaks or change tables. Assuming 60 hands per hour, 40 hours per week, and neither player, nor dealer ever leaves during a winning streak, I calculate the chance of seeing it during the year at about 3%.

Thanks for computing and sharing the results. I know there are skeptics out there, but it happened.
