I know that I am not supposed to play 6-5 blackjack, but should I find myself in this situation is there any time that it would be advantageous to double down on a blackjack instead of taking the 6-5 payout?

This was covered in a previous thread. The answer is NO, do not double down on a soft 21/Blackjack.

Okay, I hope you're happy. According to my analysis I show that you would need a True Count of +18, using the hi-lo, if blackjack pays 6-5, and the dealer were showing a 5, and dealer hits a soft 17, for doubling to be the right play.

Not that you asked, but if a blackjack paid 3-2, you would wait until a True Count of +27.

These answers are theoretical, and assume that the distribution of cards within a group (small, neutral, large) are equal, and the number of neutral cards per rank is equal to the average number of combined small and large cards per rank.

I would trust a random simulation more than my figures, but mine should be right or within 1. Here is the perfect opportunity for QFIT to chime in.

Too put it in perspective, I believe you need a TC of +13 to double on a soft 21 after splitting 10's and catching an ace. Someone can check that for me if they wish.

If your bet is low enough, then you can do it, as well as split tens, more for the comedic value of everyone's response than for a real odds advantage.


If I find a $1 table, which usually pays even money for BJ!, I'll sit for a while, just so I can double those BJs and split the tens...

If you guys want Norm to come here to post (seems odd people would want that, IMO).....you can't just say Norm or QFIT....ya gotta type something that'll show up on his google search. Like Norm Wattenberger or KJ kewlj kewljason shouldn't be banned or Hilo is the best count or I'm not interested in forum wars or fights.

I predict Norm will be here within 5 minutes of this being posted.
