Basically, ‘betting systems’ can be divided into 3 categories:
Positive progression betting – increasing your bet when you win; these are popular because they don’t require a large bank roll.
Negative progression betting system: increasing the bet when you lose. These systems require a larger bank roll and are mostly used to force a winning outcome after a losing streak. This type of system is extremely risky and worth avoiding.
Insurance betting systems: decreasing the amount of your bet when you win. This type of system is usually referred to as ‘playing it safe’.
Below is a brief list and description of some of the more popular betting systems. Some people might find this information helpful and indeed, some individuals swear by the reliability of such systems. However, before you attempt to employ any of these techniques, it’s important to realize that there is no sure-fire solution and ALL ‘betting systems’ are generally flawed when exposed to REAL mathematical probabilities.Remember, they call it gambling for a reason – do NOT rely on one particular system as a fool-proof guarantee of success; all of them are from it.
Perhaps the best place to begin is a presentation of what’s commonly known as “gambler’s fallacy.” Basically, describes gambler’s fallacy the commonly-held, but misinformed, assumption that an event that hasn’t happened recently becomes overdue and thus, more likely to occur. In other words, just because an event (such as the roulette wheel eventually resulting in a ‘black’ result) hasn’t happened in a while, the mathematics does NOT change. Therefore, relying on the likelihood of something ‘coming due’ is a bad habit to get into and, more importantly, factually inaccurate.
One of the older systems and very easy to use, the martingale system is based on the premise of losing an infinite amount of times in a row and is mostly applied to ‘even money’ bets. Basically, you begin with one bet and if you win, you begin again with another bet. If you lose, however, you double the last bet you lost. So, as you can see, this is a negative progression betting system (i.e. very risky and requiring a very large bankroll). It’s based on the premise that, eventually, you MUST win at some point and when you do so, you’ll recover all of your losses plus one unit. The problem lies with the fact that many casinos impose house limits and if you hit that and lose, this theory loses any validity it carried.
Basically a combination of the martingale system and an insurance system, the D’Alenbert strategy calls for raising your bet one unit after each time you lose and lowering your bet one unit after each winning bet. So, basically what you’re doing is trying to compensate for you losses with slightly larger bets after losing while also conserving some of your winnings after each winning bet. Slightly safer than the Martingale system, but as will all such strategies, nothing is ever certain.
