Welcome — What This Is

A course for people who want to understand the race.

Theory: what you are learning

Do Your Homework is the MWP Learn course in horse-race handicapping. Handicapping means studying a race to estimate what each horse is capable of doing today, against these opponents, under these conditions. Then you compare those estimates with the prices on offer.

Mr. World Pool is the toolkit we use: performance ratings, an Expected Rating model, form records and statistics that make racing in different countries readable on one scale. It is an independent form product, with no connection to the Hong Kong Jockey Club or its World Pool betting service. The course teaches you to use those tools and to question what they show you.

MWP is not a tipping service. I want you to reach decisions you can explain, including the decision to leave a race alone. You don't have to become a professional bettor to enjoy that work. Understanding why a race unfolded the way it did is half the pleasure.

I built MWP for myself. It is the form I use, and it grew out of years of making ratings and studying races. These days my own betting leans more on modelling, but I still like sitting down with a card and working through it by hand. The two approaches feed each other. Neither of them excuses a bad price.

You can use most of this course with another form service or your own database. The rating scale and the tools belong to MWP. The habits travel with you: comparing evidence, estimating chances and checking your decisions afterwards.

The questions behind every race

Three questions come back in every chapter.

Is the horse good enough? Look for the level it usually runs to, not just the highest figure on the page. Then compare that level with today's field.

Is it ready to deliver today? A capable horse may be returning from a break, improving through a campaign or recovering from a hard race. Preparation matters. You can look at the evidence of readiness without pretending to read the trainer's mind.

Will today's conditions let it deliver? Distance, surface, going, draw and pace all change the task. Some horses will probably get a comfortable run. Others need several things to go their way.

The answers feed a probability estimate. Only then do you ask whether the price pays enough for the risk, and after that, how much to stake, if anything.

A strong horse can be a poor bet. An uncertain horse can be interesting at a generous enough price. Most of the work happens between those two sentences.

Price changes the decision

We use decimal odds throughout. They include the stake: a winning one-unit bet at 5.00 returns five units, four of them profit. In fractional odds that's 4/1.

For a win bet, the break-even chance is one divided by the decimal odds. At 2.00 the horse has to win more than 50% of the time before costs. At 5.00 it needs more than 20%.

Say a horse genuinely has a 60% chance and you can back it at 1.50. The expected return is 0.60 × 1.50 = 0.90 per unit, so on average you lose a tenth of everything you stake. The horse wins more often than it loses, and it's still a bad bet.

A horse with a genuine 10% chance at 16.00 has an expected return of 1.60 per unit. It loses most of its races, but the price more than pays for that, if the 10% is right.

The hard word in both examples is genuine. Your estimate is an opinion to test, not a fact because you wrote it down. This is still gambling, and you can lose your stake. Calling a bet value doesn't make it safe.

The course is for adults, 18 and over. If losing the money would hurt, or betting stops feeling like a choice, the right stake is zero. Help is free and confidential. In Australia, the National Gambling Helpline is 1800 858 858; in Hong Kong, the counselling hotline is 1834 633; in Britain, the National Gambling Helpline is 0808 8020 133; in Ireland, GamblingCare is 1800 936 725. The course home page also lists the United States and Sweden and says what to search for anywhere else, and "Help with gambling" at the foot of every page opens the same list.

Why share the tools?

A fair question, and one to ask of anything you're sold: if the numbers help, why make them available?

Market size decides it. In a small pool, sharing a useful view can ruin the price you were hoping to take, so some of my work in the small Scandinavian markets stays private. The big international markets are different. They have more liquidity, far more races than I can study myself, and room for many people to use the same starting information in different ways.

There is a business reason too. A useful product earns differently over time from my own betting, and neither income is guaranteed. I keep deciding how much to publish rather than promising that every number I make will be public.

The numbers are published through MWP itself. There is no raw-data feed or API. A number fewer people have can be useful, but scarcity on its own isn't an edge. You still have to make the better decision at the price.

How to use the course

The first three chapters set up the rating and the decision process. Part 2 looks at the horse, its preparation and the race it is likely to get. The last two parts turn that work into prices, bets and a record you can learn from.

A few racing terms before you start. Form is a horse's record of past races. Going is the condition of the ground. Draw is the horse's starting position in the stalls. Pace is how fast the race is run at each stage, which decides how the field spends its energy. In a handicap, the better-rated horses carry more weight to narrow the gaps; it doesn't give the runners equal chances.

Start with one jurisdiction and a manageable number of races, and widen out later. The exercises need no money, only a written answer before the result appears.

Practical: find your way around a card

Quiz: facts, opinions and prices

Optional practice: the same questions in different countries

These are orientation cases, not a collection of proven winning bets. A word on how the course picks its races: each one is there to teach something, and many were chosen after the race, because of the horse that won. That makes the cases a flattering sample. Real betting at a fair price means far more losers than you will see here, and Chapters 12 and 15 come back to it. Keep the outcome hidden. You're done with each one once you can separate what you observed from what you concluded.

Up next: what the rating measures, and how to keep a past performance separate from today's expectation.
