The latest BST session should have turned out very badly. It didn't. Maybe next time?

_
The conventional wisdom holds that because the house advantage at casino table games is immutable and invincible, any attempt to beat it must ultimately prove fruitless.

The message from the experts is that you can't win, so trying is a waste of time.

They tell me to "just do the math," and my problem is that the more math I do (applying far more strict standards of fairness and accuracy than most mathematicians I have encountered) the shakier and more vulnerable the house advantage proves to be.

In this post, fewer words, more pictures. Here they are (and as always, clicking on any image will make it larger and fully legible)...


I'm not a big fan of double-up or Martingale betting, not because it doesn't work (in spite of what house-trained mythematicians will tell you, it really does) but because it is quickly spotted by pit personnel who will then do whatever it takes to stop it. The chart above shows that against the current BST outcomes, the traditional Martingale and my more aggressive version of it both overcame the house edge without exceeding the house limit I imposed (a house limit being the highest permitted table limit). The summary above also reminds us that target betting is a far better way to go.

The data below cover the current batch of BST trials (#15) and have a lot to tell us about the inherent weakness of the house advantage, as long as it is not bolstered by tight spread limits. Casinos do all they can to prevent players from "betting wide" but gamblers are themselves the strictest enforcers of this damaging rule. Very few weekend punters spread wider than 1-5, and those that do (mostly high rollers) do it randomly. Bad idea!



Of all the claims I have made for my methods, the one that attracts the most flack is the target betting axiom that "if you win more when you win than you lose when you lose, then losing more often than you win won't hurt you." Yeah, I get it, they tell me, "You bet more when you know you are going to win and less when you know you are going to lose." Funny stuff! And very un-smart. You don't need a crystal ball to achieve this important objective, but you do need a strict set of rules and the discipline to apply them consistently.



In the latest BST contest, as in most of them, target betting could not succeed against a $5-$1,000 spread limit. And as always, I am not in the least surprised. Don't tell me that the bets that target betting requires are too high or that the risks my methods impose are beyond the reach of the average part-time punter. Tight spreads are far more dangerous than a controlled progression, as you can see (AGAIN) from the latest BST numbers. And this whole thing is not about making "recreational gamblers" rich on a shoestring budget: it's about proving that as well as not deserving to win as much as they do, casinos do not have to win as much as they do. The Math repeatedly proves that point.

Waiting for the other shoe to drop could take a lifetime (and it may never happen at all!)

The assumption that mythematicians like to cling on to and batter us about the head with is that if you are certain to lose more bets than you win in the long run then you must also be doomed to lose more money than you win.

They don't care that models and data summaries covering millions of outcomes with a clear overall house edge include countless thousands of profitable series that consisted of more losses than wins.

They just keep chanting that the sample, however large, was "not representative" and warn that at some point, the sum total of all losses must exceed the sum total of all wins. So, beware, insolent peasants, and be ready to pay your dues.

Here's the latest BST log:

It's true that from time to time, a win-loss pattern will set in that has a succession of isolated wins (wins immediately followed by one or more losses). And if the PB value is outside of your MSL ("do over") range, two wins separated by one loss will not save the day before the cavalry rides over the hill in the form of "twins" (two wins in succession!).

The horrors of long stretches in which the NB keeps jumping skyward with each failed EOS bet diminish dramatically as your confidence grows. But it never hurts to keep in mind that you are playing a game in which the odds are almost always against you.

As I explained in the summary, table limits usually extend the battle to climb out of the hole because without wiggle room in your bet values, the green ceiling forces you to keep betting the max until the WLP switches to a more positive trend.

But that assumes you do not have the option to back away from the layout that has put you in the hole, and resume play at a location where you can continue to strictly follow the target betting rules.

Here are the target betting bets applied by the spreadsheet model to the outcomes in the pencil log shown above. The final totals differ from the numbers at the bottom of the log because the recommended responses to dealer naturals and dealer 21s are not applied. I'll fix that at some point, but my purpose here is to keep on demonstrating that more lost bets does not translate to more lost dough!

The blocks of numbers in the spreadsheet line up with the checks and crosses etc. in the log, so if you print out the three images, it should be fairly easy to match them up.

As always, there were numerous turnarounds that delivered a profit from a negative situation, and overall, the house edge was almost 2.0% gross, confirming that more hands went south than north, so to speak.

The NET AV was +2.79%, demonstrating once again that properly-applied doubles/splits really do deliver a player advantage. We already knew that a 3-2 pay-off is better for the bottom line than a 1-1 pay-off!

Real math (as opposed to mythematics) is reassuringly predictable when it comes to data from games of chance. An analysis of recovered series will invariably show that one third contained fewer wins than losses, one third had an equal number of wins and losses, and one third had fewer losses than wins. Surprise!

The bigger the sample, the more precise the distribution becomes. This set (the outcomes from 090309) made a liar out of me, temporarily, with 45 positive series, 18 negatives, and 21 break-evens, but that's not the norm. The current trial sample (all bets against Ken Smith's BST app) are also out of whack (547/369/315) but the distribution will settle down eventually!
