Staking systems for BEAT THE BOOKIE !!

Many people have formulated staking systems in an attempt to "beat the bookie", but most still accept that no staking system can make an unprofitable system profitable over time. Widely-used systems include:

* Fixed stakes – a traditional system of staking the same amount on each selection. This method suits conservative punters if the stake remains below 5% of the bank.
* Fixed profits – the stakes vary based on the odds to ensure the same profit from each winning selection. This method suits conservative punters well, although if the profitability of one's bets varies independently of the odds the bettor simply reduces his or her cash flow.
* Due-column betting – A variation on fixed profits betting in which the bettor sets a target profit and then calculates a bet size that will make this profit, adding any losses to the target. For example, to make a target of $100 profit a bettor would wager $50 at odds of 2 to 1. If the bet loses, the target becomes $150. If the next bet is also at odds of 2 to 1, the wager therefore becomes $75. This type of wagering can prove ruinous in the long run.
* Kelly (optimal) – the punter needs to estimate fair odds (in the European/decimal format) and then calculate the stake using :

Stake= (Odds/(Fair odds-1))/(Odds-1) Many times used with a divider (most commonly 4 or 8) depending on your bankroll (for betting)

This system developed for baccarat, but many people recommend it for horserace betting. In betting on horse-races, punters further adjust the stake to allow for inaccuracy in estimating fair odds. Computer simulations suggest that in betting horseraces Kelly betting increases losses during losing streaks, that it fails to demonstrate superiority over fixed-stakes betting unless making large numbers of bets (a drawback in horserace betting because the bettor usually has no reasonable expectation that any betting advantage he or she has will last over a long series of bets), and that inappropriate statistical analyses have exaggerated its profitability.

* Martingale – A system based on staking enough each time to recover losses from previous bet(s) until one wins. The Martingale guarantees failure - it would only work if the bettor has an unlimited bankroll, the bookmaker has no limit on the size of bets and neither party ever dies.
