"Send enquires about this paper to our newly acquired private island in the Bahamas." :-)

One of the most depressing things I realized when I learned to count cards, and confer upon myself a small but meaningful advantage in the game of Blackjack, was that the casinos simply ask you to leave if you win too much. That put an upper limit on the rate at which one could win. The folks who figure out slot machines have a much better time of it because it takes longer for the casinos to figure out they are losing money.

I used to use the betfair platform until it they blocked themselves from being viewed in Canada for some strange reason right after they were purchased by ladbrokes I believe it was.

Anyways, after playing with them for a few years, I was horrified to learn about their 60% tax on consistent winners that they have dubbed a "premium charge".

Found some sort of edge to exploit and reap profits?

Betfair doesn't even care to talk to you to ask you what you are doing, they will just charge you 60% of your winnings once you go over a certain limit. [0]

Betfair merged with Paddy Power, not Ladbrokes.

They probably stopped offering their service in Canada due to unclear licensing and operating regulations for their Exchange product. It has happened in a number of other jurisdictions too. What you need is a good friend or relative in the UK or Ireland, and a VPN.

However there are now other exchange betting options, with at least some degree of liquidity - Betdaq, Smarkets and Matchbook for example.

Professional punters still have ways of getting on, which circumvent the online restrictions. Once all their accounts have been limited or closed with the online bookmakers, the next step is usually a string of agents across multiple locations, working on commission, and placing bets on the punter's behalf. It's still possible to get on for farely large amounts like this.

If horse racing is your game, Hong Kong is where the money is at. Huge totalliser pools (park-mutual) where the size of an individual's bet is unlikely to move the market very much. Now that there is co-mingling with a number of other pools around the world, one doesn't have to be in HK to bet there.

I've recently started having a proper go at the Daily Fantasy Sport option, now that Draft Kings has opened up in the UK and a few other European locations. Moneyball in Australia is also quite good, albeit much smaller prize pools. However, this weekend they just launched a DFS horse racing product which looks pretty interesting.

Minor nitpick re: horse racing: it's "totalisator" (usually abbreviated as "tote") and refers to the machine that keeps track of the pools and odds, and the term for the betting pool type is "parimutuel".

Fun fact: totalisators were originally mechanical computers that were used to price betting pools around the turn of the 20th century (http://www.computerhistory.org/atchm/racetrack-betting-mecha...).

That's good to know.

But do they impose the same sort of "60% winners tax" that betfair does? Or anything close to that?

Because if so, I wouldn't even bother signing up.

I don't need to gamble that badly!

Re:Beating the bookies – how the online sports betting marke... by phillc73 on Sunday October 22, 2017 @03:32AM (#15525623)
The so called "60% winners tax" doesn't kick in on Betfair, according to the linked article above, until you've reached a total lifetime profit of £250,000. Up until that point you'll still pay the normal 2%-5% commission in winnings.

How long do you estimate it will take you to clear £250k profit in Betfair? I'd say sign up and worry about it when it's likely to happen.

Re:Beating the bookies – how the online sports betting marke... by joosters on Saturday October 21, 2017 @09:31PM (#15524634)
Unfortunately the other betting exchanges have far far less liquidity than Betfair, and much of the bets on offer are from bots that are simply mirroring the odds on Betfair (with their own margin added on)

Basically, all the money goes on Betfair because that’s where all the money is. It’s a vicious circle, great for BF and very difficult for any competitors to break in to the market.

Re:Beating the bookies – how the online sports betting marke... by phillc73 on Sunday October 22, 2017 @03:36AM (#15525634)
Betfair is for sure the most liquid. Smarkets and Matchbook are growing. I've not used Betdaq.

However, if people are worried about hitting the Premium Commission levels on Betfair, and the other exchanges are mirroring prices, then surely it's worthwhile spreading stakes around.

Site Vs API are identical. There may be some extra latency (order of milliseconds) on the site due to render time etc but they both use the same underlying data source.

Do you mean the Betfair lines? I think their market is pretty accurate. More so than many traditional bookmakers, although a lot of them use Betfair to make their own markets now, so there's very little chance of arbitrage between them.

I've written an R library for the Betfair API[1], which I use every day to retrieve prices.

Re:Beating the bookies – how the online sports betting marke... by the_cat_kittles on Sunday October 22, 2017 @02:18PM (#15528138)
sorry i meant accurate in terms of what they show on the site vs what you can actually get when you try to trade. someone else answered that they are indeed accurate- has that been your experience?
Re:Beating the bookies – how the online sports betting marke... by phillc73 on Sunday October 22, 2017 @02:45PM (#15528265)
The Betfair prices depend on market depth. It's data available through the API, so you can have a pretty good idea of what price you will be able to strike for any given bet size.

My experience with traditional bookmakers has been severely limited or closed accounts very quickly. I haven't used a traditional bookmaker for a few years now, betting solely on the exchanges and 90% of the time with Betfair. I do still have a Corals account, which was somewhat un-restricted through leveraging a contact within the company, but I think my max bet is only £200. As I haven't used it for while, I don't like the chances of it staying that way if I started pumping winning bets through it.

There have been various investigations conducted on Betfair prices, and they are usually a few ticks above traditional bookmaker odds. However, the over round on highly liquid Betfair markets is only 1%-2%, whereas a traditional bookmaker is generally significantly higher, more like 110%-120%, depending on the event.

One way to extract the best results from traditional bookmarkers, as far as horse racing is concerned, is to bet with Best Odds Guaranteed. In this scenario, you'll receive a winning payout at the highest price the selection reached, rather than the price at which you struck your bet. This works best in overnight markets, that is placing bets the night before the race. However, this route is also one of the quickest to restriction and closure.

Re:Beating the bookies – how the online sports betting marke... by seanalltogether on Saturday October 21, 2017 @07:29PM (#15524186)
I'm confused, since betfair is an exchange aren't they just taking a cut of the action? Why would they add a heavy tax onto profits which would just drive heavy bettors away?
Re:Beating the bookies – how the online sports betting marke... by joosters on Saturday October 21, 2017 @09:19PM (#15524584)
They do it because they can, and for many gamblers, Betfair is the only place they can realistically keep betting at. Other bookies will restrict winning gamblers’ stakes or refuse their bets, and other betting exchanges have far less liquidity than Betfair. So, successful punters on Betfair just have to grin and bear it...

n.b. The 20-60% ‘premium charge’ that Betfair inflict on long-term winners is different to their standard 2%-5% commission that they charge everyone for any net profit on a market. The premium charge is calculated weekly over a customer’s profit & loss. So its effect is not the same as if the commission was as high as 60% per bet. Like a tax, the PC won’t make a profitable gambler unprofitable, it ‘just’ means Betfair get to keep more of your profits.

It’s also worth pointing out that the standard commission (2-5%) can add up to far more than 60% of your winnings anyway. As no-one wins every bet they place, the commission will become a larger percentage of your net profit. For example, Betfair charge me 2% commission and I ‘qualify’ for their premium charge of 40% - but my betting patterns already result in over 40% of my gross profit going to Betfair :(

Re:Beating the bookies – how the online sports betting marke... by GigabyteCoin on Saturday October 21, 2017 @08:18PM (#15524376)
That's the scam.

They get you hooked thinking they are only taking 5% or whatever it was... and from pretty much everybody who bets there, they do only take 5%.

But all of the "smart money" gets taxed at 60% when they inevitably take all of the losers money who only paid 5%.

So in essence, they are doing exactly as you suggested... "they're just taking a cut of the action." But it's a 65% cut!

Re:Beating the bookies – how the online sports betting marke... by joosters on Saturday October 21, 2017 @09:26PM (#15524616)
It’s not quite as bad as that - see my other comment; the calculation of the charge doesn’t mean you pay 5%+60% commission on winning bets. That kind of fee would be impossible to sustain, no-one has that kind of profit margin on their betting. The commission % charge and the PC % charge don’t work in the same way.

On the flip side, a great many people pay far higher than 60% of their net profits to Betfair... most will have paid over 100%...

Re:Beating the bookies – how the online sports betting marke... by downandout on Saturday October 21, 2017 @05:13PM (#15523651)
the casinos simply ask you to leave if you win too much.

I was actually backed off from the first place I went to after I learned how to count cards while I was losing. If the pit boss or dealers know how to count themselves and identify you as a counter, they want no part of it. In most cases, they'll either "flat bet" you (tell you that your initial bet is your maximum), or they'll tell you that you cannot play blackjack there. Actual barrings usually don't occur until the second or third offense.

I guess you could always count from the sidelines and bet only in advantage spots. Not very practical I suppose but card counting in general seems pretty implausible these days
Re:Beating the bookies – how the online sports betting marke... by DSMan195276 on Saturday October 21, 2017 @09:44PM (#15524676)
One strategy I know of is to have multiple people. One person sits at the table and always bets low, the other always bets high but only sits down if the person at the table signals to them that the odds are good (They can be off doing other stuff while the low-better is doing the counting, so they're not just standing around waiting).

You're still right though, the odds aren't that great and once they get a hint you're doing something weird you'll get thrown out.

Most of the casinos are publicly traded, so for them to be involved someone would have to be lying on the financial statements submitted to the SEC. SOX would make that illegal at best and I believe reward anyone who blew the whistle on it with a substantial reward.

So if they are involved it would be more likely related to contracted services and such where you could pad the actual cost by a large amount and no one is going to look too closely.

Casino licenses are contingent upon offering a fair game at stated odds. The odds are allowed to benefit the house, of course, since that's how running a casino becomes a sustainable, profitable enterprise, but the stated odds cannot be dynamically changed in the middle of the game to benefit the house.

Published blackjack odds depend on "dumb" reshuffles. If the house is "smartly" reshuffling the deck to reduce house payouts, then the published odds do not match the real odds, which is illegal.

Re:Beating the bookies – how the online sports betting marke... by danmaz74 on Sunday October 22, 2017 @06:47AM (#15526112)
Correct me if I'm wrong, but I think that not being allowed to count means that you should treat odds as if the cards were extracted from an infinite stack with a given statistical distribution of cards. Reshuffling when you only extracted a low number of cards from a finite stack basically approximates the infinite stack, so, the odds should be exactly as expected.
Re:Beating the bookies – how the online sports betting marke... by solatic on Sunday October 22, 2017 @02:28PM (#15528170)
Except that the stack isn't infinite. There's a statistical difference between playing off a physical deck and playing off a random number generator, and in a physical deck, the dealing of various cards increases the relative odds that the other cards will come up later in the deck. It's the statistical foundation upon which card counting works.

Imagining that the physical deck is a virtual deck does not make it so. In an RNG-populated/virtual deck, there is a small but still real chance that, for instance, 20 aces could be dealt in a row, which is why game programmers use techniques like shuffle bags to prevent that from happening. An "infinite" physical deck, that was actually "infinite", would suffer from the same problem, and would need a physical solution, which would affect the odds which the casino is legally obligated to publish and adhere to.

> It's the statistical foundation upon which card counting works.

Exactly, so, if counting cards if forbidden (I'm not arguing if that is right or not), then having that statistical foundation isn't useful. As a different comment suggested, reshuffling at a fixed point (say, after one third of the cards have been dealt) should solve the problem in practice, also preventing the house to use counting in a meaningful way.

Re:Beating the bookies – how the online sports betting marke... by Khoth on Sunday October 22, 2017 @10:04AM (#15526874)
That would be true if the casino always reshuffled after a certain number of cards came out.

But a dishonest casino could do the same card counting that players can do, and reshuffle when the count favours the players.

Re:Beating the bookies – how the online sports betting marke... by danmaz74 on Monday October 23, 2017 @11:25AM (#15533837)
I agree that having a fixed number of cards between reshuffles would be the fairest solution.
Re:Beating the bookies – how the online sports betting marke... by nasredin on Saturday October 21, 2017 @07:38PM (#15524220)
And when the dealer messes up the count you can have one hell of an exit!

Very loudly:

"Aha! You should have shuffled the cards! Messed up the count didn't you!"

card counting is about a few percentage points advantage wrung out over hundreds of hands, you would never get a jackpot moment like that if you are doing it correctly.

I've worked for an online bookie. I've also worked for an outfit that bets (on horses mainly).

The online bookie will indeed ban or limit winning accounts or anyone they suspect of cheating or betting smartly. Anyone betting large amounts dumbly gets taken out to nice dinners etc.

The company that bets on horses bets using exchanges, because bookmakers would tend to kick them out. The abstract of this paper is pretty much 101 to those guys who do some advanced stuff I can't talk about to make predictions.

Good luck!

I don't think your reasoning is correct.

The entire lure of gambling is that some players can make money. The house always plays that up.

But if the house always wins, that hope they're selling disappears.

Re:Beating the bookies – how the online sports betting marke... by brucen on Sunday October 22, 2017 @07:02AM (#15526173)
I think it's more so there is a chance to come out ahead. E.g., everyone sitting on a pokie machine absolutely knows in the long run, the casino wins out. However they are hoping they are the 1/million that gets the jackpot and "beats" it. The same reason people buy lottery tickets I guess.

Other people simply like the social aspect of a lot of games (craps, poker, blackjack, roulette) and the excitement/thrill of seeing some big winners. You know in the long run you are losing X%, but still go to burn hours and have some fun.

Do you actually make money now that you can count?

I went to high school in Las Vegas, so when I went to college everyone "assumed" I could count cards. After realizing it was a losing strategy to tell people that couldn't count, I looked up the basic strategy.

I wrote a computer program to simulate the game and the strategy and had the computer play hands until it was winning consistently. Generally it wasn't so much "counting cards" as it was "counting face cards and 10's, and changing your betting strategy based on that count."

Just thinking about the mechanics of a card deck, face cards, 13 card suits, etc. Turned out to be really useful in playing Bridge as well.

Re:Beating the bookies – how the online sports betting marke... by StanislavPetrov on Sunday October 22, 2017 @05:42AM (#15525914)
One main difference is that the vast majority of sports betting occurs outside of casinos and "legality". The other huge difference is that the entity making the picks doesn't necessarily have to be the person placing the bets. There is a well established term in sports betting for one who places a bet for someone else, "beard". Fortunately for the bookies/casinos and the few winning bettors, there are always plenty of losing bettors to keep the system afloat and profitable for everyone with an edge.
