Hi all -

New poster here. I know you should always avoid 6-5 tables but I am going on a trip with some friends and that is the only thing offered. So my question is do the odds favor you doubling your hand rather than taking the 6-5 payout for any dealer starting hands?

Thanks in advance for any and all information!

Under basic strategy you should not double down. If you are counting, then that could be a different story.
The race is not always to the swift, nor the battle to the strong; but that is the way to bet.

No*.

Fortunately house rules at many tables do not allow doubling or hitting a soft 21, natural or split.

They may offer a different 21 game like Super Fun 21 or Spanish 21 that does better for you. Basic strategies for these will be different than Blackjack, but if you have time to ask this on a forum, you have time to look those up.

*I won't get sore if someone has better math on this and contradicts me.*
May the cards fall in your favor.

Thank you, Dieter. This casino does allow it. The math does not support it though?

I guess my answer wasn稚 clear enough? 6/5 basic strategy says do not double down on blackjack. That means the math does not support it. Unless the count is high enough.

It could be worth it just for the entertainment value of all the reactions of the other players.

Long run, 1.2x your bet to stand; .68x your bet to double vs 6. Other dealer hands are worse.

WoO ev data

Sometimes you miss and lose when you double.

Talk your friends into going elsewhere if you're serious; otherwise have fun spending money.
Splitting tens and then doubling your hard 11's can be quite amusing at a $3 table minimum - it's just not "the mathematically sound recommended way".
May the cards fall in your favor.

Casinos are quick to kick people out who split their tens, so I can't imagine the hospital bills when you double down on a blackjack.

Why is that?

Splitting tens is such a bad idea, the casino should welcome any fool who does it.

They'd think you're counting cards instead of making insane plays.

They may not sweat it much if you're flat betting against a continuous shuffler at a 6:5 table.

Doubling down on a blackjack would be allowed normally. At an extremely high count, it would be the right play against a 5 or 6. However, it would be an attention-getting play that most counters would avoid, even if they knew when to do it.

I've really never seen anyone DD on a blackjack.. I hope I never do ..It is just a greedy foolish thing to do plus it's not very courteous toward others at the table[ that maybe haven't seen a BJ in a while,,

There are other players at the table? I've never noticed.

Doubling down on a BJ is certainly not allowed in on-line games.

I suspect that eventually BJ will be paid 1:1 but will still be an automatic winner against a non-BJ dealer. In such a hypothetical future game, doubling down on a BJ vs 5,6 might be occasionally correct.

EDIT: But not very often, lol:

BJ pays 1;1; Single deck game, 10 cards removed: 3 aces, 4 deuces, 3 treys

AT vs 6: Stand EV=1.0, Double EV = 1.027
So many better men, a few of them friends, are dead. And a thousand thousand slimy things live on, and so do I.

Oh, here's a slightly more likely scenario:

BJ pays 1;1; Single deck game, 7 cards removed: 3 aces, 4 fives

AT vs 6: Stand EV=1.0, Double EV = 1.078.

Anticipating 'BJ pays1:1' games is like planning for the zombie apocalypse. :(

In my thousands of hours of blackjack I have never seen a player kicked out for splitting 10's. I would think the casino should encourage it.

Doubling 10-A after a ten split in a monster count is a play the breed of counters who enjoy throwing it in the casinos face live for.

There will probably be a few locals places still offering 1 table of "Full Pay 6:5", but it will be a trap.

Suited BJs pay 2:1, all others pay 1:1.
