I've been playing blackjack with my friends lately, and the person who acted as the dealer was allowing people to keep hitting after doubling down, rather than just getting one card. I told him this wasn't how the game was usually played and he stopped doing it, but I'm curious of how this rule change would effect the house edge, assuming liberal Vegas rules.

Hi, and welcome to the forum.
I can't calculate the effect, but clearly this will reduce the house edge and might well give the player an edge...

Eg. dealer dealt a 5 player dealt a 4 and a 5 (=9) and he doubles but then gets dealt a 2 to give him a rubbish total of 11. He can now hit to give a great chance of winning the hand, with a double stake, where proper rules would see him in a relatively poor position.
Take care out there. Spare a thought for the newly poor who were happy in their world just a few days ago, but whose whole way of life just collapsed..

On your typical doubles-10/11, it's not all that helpful.
On 10, you' only rehit on 2-6 when the dealer has a 7 or more.
With 11, you add the Ace but lose the 6.
With almost all the hands you want to rehit, chances are you either bust or get a small enough card to require a fifth one.
It's a good rule for the player but I don't think it's a game changer for your typical player. I imagine an AP would make better use of it.

Essentially you would also double where your chances (by hitting) exceeded 50%, so 9 vs 8-2, 8 vs 7-3, 7 vs 6 and some more soft hands.

Yes. It is fortunate perhaps that this was more a social blackjack game than a casino operation, although sometimes 'social' can involve a slight 'rake' for refreshments or something.

Sharpies might not trek across country for this rule or 'pile on' in some mad AP feeding frenzy but it would surely be of interest to them. I pretty much think that any actual casino dealer who did this would get bounced, not retrained. It would have been caught rather promptly by the Floor and by that darned Eye in the Sky though.

Hitting after double down is absolutely a help to the player. The question is can you then re-double since you can take more cards? As you described it I imagine the rule has an effect of +.1% to +.5% for the player, with my educated guess being around .25% if you can't re-double and around .45% if you can redouble. So if you're playing a game with decent rules, this could absolutely give the player an off the top edge.
Playing it correctly means you've already won.

You couldn't redouble, but interestingly enough before I joined the dealer was letting people split any hand. One person just kept splitting and resplitting, and it was kind of annoying, so I made sure they changed it to only doubles. Before that, they were splitting 10/6 , 10/5, etc, which seemed even more busted to me. And if they got another 16, they just split it again.

Is winning a ton annoying?

Yeah, was this just "friends" or were you playing to actually win money? If you were playing to actually win $, you screwed yourself really hard. All of these rules favor the player...

We were betting like 5 cents a hand, and I really didn't want to take money from my friend just because he didn't know the rules. And while winning is fun, the guy splitting over and over again really slowed down the action, so that's what I meant by annoying.

Although, even with those rules my friends were still losing money, because they didn't know the basic strategy. So I guess I certainly wasn't doing them any favors.
