Planning a budget around "Do betting strategies work?" comes first. Every betting strategy rests on two questions: what to bet on, and how much to put on each pick. The second one decides more than most people expect. A sound bankroll and a fixed staking plan keep a bad week from ending the whole budget, while a loose one turns ordinary losing runs into real damage. What follows covers the staking side, where a plan can actually be built.
Do betting strategies work, then? Staking plans control risk and cannot remove the margin built into every price. The best betting strategies, including the best betting strategy for football or any other sport, come down to picking where the bettor has real knowledge and staking with steady discipline. To create a betting strategy is to write those two parts down: a market to study and a staking rule to follow.
A betting strategy built on martingale doubles the stake after every loss, so that one win recovers everything lost plus the first stake. On paper the plan cannot fail; in practice a run of six or seven losses, which comes sooner than people think, asks for a stake sixty or a hundred times the first one. Table limits or the bankroll end the sequence long before the promised win comes.
No staking plan removes the margin built into every price; it only controls risk, so the margin stays the cost of each bet placed.
From a separate sum decided once and set aside for betting only, never refilled from rent, bills or savings when it runs low.
Yes. A record of every bet, winners and losers alike, shows what the staking plan actually returns and whether stakes have drifted from the units set.
Units make results comparable across weeks, sports and bet sizes, and they show quickly when stakes have started creeping upward after a streak.
Full Kelly trusts the bettor's own probability estimate completely, and estimates tend to be too kind, so half or a quarter of the formula keeps stakes from growing too large.
