Sorry if this is the wrong forum... just seems to get a lot more traffic than general gambling, and I figured it'd be helpful with all the Blackjack whores around here.

Anyways, I'm just wondering why you don't double down when you have 7 or 8, and the dealer's showing a bust card, like a 5 or 6.It seems that an overwhelming majority of the time, you're only taking one card anyways, so it seems like it would make sense to double the bet when you have an apparent advantage.

Anyone?

Choose rules for current casino/table and you get optimal strategy.

Yep... I'e been using optimal strategy charts, but I was just wondering if anyone could explain why you don't double in those 4 particular spots. Intuitively, it seems like it would be +EV to double there.

Because it doesnīt matter how many times you take 1 or 2 cards more, but how many times after drawing those cards your hand wins in a "showdown". You donīt make enough good hands with 7 or 8 if the hand goes to a "showdown" like you do with 9, 10 or 11.

Dealer busts with 6 about 45% of time and with 5 about 36% time, so not THAT often. And when dealer doesnīt bust with these hands, itīs more usual 20 or 21 than 17-18. Thatīs why you donīt double on 7 or 8 in those spots.

I used to have my own little gut feelings while playing BJ, but then I was like...

"Well the guy who made this chart probably knows a lot more about the math/strategy behind Black-Jack than I do."

I've always followed a good chart while playing BJ, every single hand exaclty as a chart says,('cept for [censored] mis-clicks) and I have done very well casino bonus whoring all-in-all.

It's mindless easy money...chart says this, click that, next hand, chart says this, click that, next hand....blah blah blah.

Awesome.
Thanks for the help..
I think I just started trying to think of ways to make InterCasino clear faster, and that was the only thing I could think of.

You'd be surprised how many people stay when someone is playing horribly. If alcohol is in the mix, some view it as funny and stay regardless of the results.

As for splitting 20's, why split a winner?

A little less than 1/4 of the bet size on each hand where you split tens against a 6, more against a 5. The strategy table at http://www.beatingbonuses.com/blackjack.htm shows blending colors when the difference in expected value is below 0.15 . This is not one of those points.

I was sitting at a blackjack table in Vegas when this guy went to split 10's. This little old lady looks at him and says "If you had a 12 inch [censored] would you split that too?"

10-10 vs 6 has an EV of +.70 when you stand and when you split your ev is +.47. So you still win more then you lose when you split, but not as much as you would for just standing.

Here's something I've always wondered. Do you surrender two 8s against a 10 or are they supposed to be split?

Under typical online BJ rules, splitting has a slight edge. Some may consider this difference negligible, and may prefer surrendering to reduce risk of a big loss.

The expected loss from splitting is ~-0.48.
The expected loss from surrendering is -0.5.

Split (unless dealer does not peek for blackjack).

The added EV of re-hitting when you draw a 2-4 on values 7 and 8 are overwhelmingly positive over the marginal EV of having doubled your bet when you draw a 10, far more so than having an extra bet in when you have a pat hand 12-16 against the dealer 5-6.
