Before you take a price, twelve things to check
A checklist does not improve an estimate. It prevents the small, avoidable errors that make a good estimate worthless — the wrong market, the wrong price, the wrong rule, the stake that was never affordable in the first place.
§01The price itself
- Is this the best price available to me? Value is created by comparison. A price that is an edge at one operator is often not one at another.
- What is the implied chance? Divide one by the decimal price. If you cannot state it, you are not comparing anything.
- What is the total implied chance of the market? Add every price. Above roughly 108% the market is expensive and the bar is high.
- Is my estimate larger than the implied chance? If it is not, there is no bet to consider at this price, however good the reasoning feels.
- Is my estimate based on one observation counted several times? Correlated inputs manufacture confidence. Check that each input could differ independently.
- Price
- Estimate
- Comparison
§02The market and its rules
- Is this the market I think it is? Handicap, match-winner, totals and outrights settle on different things, and a drawn match sits inside some and outside others.
- Does extra time or a replay count? The settlement period is written by the operator and changes the event being priced.
- What happens on a dead heat or a void? Split stakes and returned stakes are different outcomes and must be part of the estimate.
- Can I actually get money on at this price? A price with a limit below your stake is worth only the amount you can get on.
Twice this year, someone lost money on the right team
The most expensive errors in betting are not bad selections. They are good selections on the wrong market, settled under rules the bettor never read.
§03The record
- Have I written the estimated chance before placing this bet? Filling it in afterwards is the one thing that makes a record untrustworthy.
- Am I logging this bet even if it feels uninteresting? Selective logging reproduces its bias in every conclusion drawn from it.
- Is the stake in bankroll units? Units survive a change of stakes; money amounts do not compare across a sample.
§04The stops — the checks that apply whatever the arithmetic says
- Am I staking money I would need for something else? If yes, the bet is not a value bet. It is a bet you cannot afford to lose.
- Am I increasing the stake to recover an earlier loss? That is chasing, and no edge calculation justifies it.
- Has this stopped being a decision and become a habit? Frequency, secrecy and borrowing to bet are the signals worth taking seriously.
- Do I know where to get help if it stops being fun? Every country with legal betting has a confidential helpline for bettors and for the people around them.
Run it against a live market once
A checklist read as theory changes nothing. The sponsored partner link below opens a live market on the partner operator so the twelve checks can be run against a real price, at no extra cost to you — and the correct outcome of the exercise is frequently that the checks fail and no bet is placed.
Affiliate disclosure and risk warning
Every affiliate link on this page and in the header is a sponsored link to a partner operator, and we may be paid if you open an account through it, at no extra cost to you. That link pays us; it does not price the market for you, and it is never a recommendation to bet. Nothing on this page is betting, financial or legal advice, and no price, model or result on it is a prediction. 18+ only. Betting is gambling: a measured edge is an estimate and the estimate can be wrong, the operator's margin is built into every price you are offered, and a selection with positive expected value can still lose — including many times in a row. Gambling can cause serious financial harm, including debt and damage to relationships and mental health. Never stake money you cannot afford to lose, never borrow to bet, and never increase a stake to chase a loss. Free, confidential support is available in most countries from national gambling-harm helplines, for bettors and for the people around them.
