Help me place my bet

You've got a feeling about a game, a fight, a series, a match. You don't have the words for it, and the bet slip wants numbers.

Say it however you'd say it to a mate. We'll work out what you meant, find every line it implies, and tell you which side of each one your read is actually on.

Every sport, no data needed

Check the price before you take it.

These three tools do not know or care what sport this is. Boxing rounds, esports maps, darts 180s, cricket extras, tennis double faults — if a book publishes a line or a price series, they work. Give them your own number wherever we have no base rates — though football (16 leagues), ATP tennis, the NBA, the NFL and T20 cricket now carry measured ones.

Three questions, in order: is their line where mine is, have they split it properly between the two sides, and are they thinking about this market at all.

You can find this out yourself, for any market, without a data feed. Open the board, pick one market, and copy the price for that market across ten or more of this weekend's fixtures. Paste them below.

A book that models a market carefully quotes a different price for every fixture. A book that has defaulted to a league average quotes nearly the same price over and over. The spread of its own prices gives away how much it knows, before you check a single result.

The quickest version. A book choosing where to put a line has published its own forecast, for free, on the board. Type theirs and we will show you ours.

Across 9,451 matches the handicap line predicts the actual result at R² 0.220 whilst the handicap price predicts it at 0.000, and the line's slope against the outcome is 1.056. The number on the board is the forecast. The price beside it is almost pure margin.

The split test. Where a book sells each side separately but not the match total, the two halves have to add up. Books get the total right, because that is where their liability sits, and divide it between the teams crudely. Type the number each side is priced around.

The longer version. How hard is this book thinking about this market at all?

Why this works

Across 130 league-market-season cells covering 2,684 matches, the dispersion of a bookmaker's own implied probabilities correlates with how much those prices actually explain results at r = +0.93. Match-result prices spread widely and explain a lot. Over/under prices spread less and explain less. Asian handicap prices barely spread at all, because there the information sits in the handicap line rather than the price, and the measurement correctly reports nothing.

The useful quantity is the gap. Where a metric is predictable from who is playing but the book's prices for it do not move, the book has defaulted and your read has somewhere to go. Where the prices move as much as the outcome does, it has already thought about it, and so has everyone else.

No stake required

You don't have to bet to keep it competitive.

Start a league with your mates. Everyone calls the games in their own words, nobody stakes a penny, and at the end of the season one of you has bragging rights and the rest have to sit there and take it.

Every saved read stakes 10 notional points at the price we quoted. Landed, you win at that price. Didn't, you lose the ten. Same maths as betting, none of the money.
