Anyone who has ever read a horse racing betting tips piece is likely to have encountered the acronym NAP. But what a NAP is isn’t always entirely clear, nor is how punters are meant to use this information in relation to wagering on betting sites.

We have answered both those queries, unpacking what a NAP is and how bettors learning how to bet on sports need to treat a NAP with an element of caution.

A NAP in betting is a tipster's single most confident selection from all his tips competing that day. The sports betting term is most commonly associated with horse racing, where tipsters assess runners across a card before highlighting the one they consider their strongest pick.

A NAP is a subjective opinion from an individual tipster, rather than an official rating, algorithm or guaranteed winner. The selection reflects that person's assessment of the available form, conditions and other factors at the time of writing.

Newspaper, website and betting-service tipsters typically highlight one NAP per day, or sometimes one per meeting. The aim is to identify their strongest opinion without requiring readers to consider every selection they have made.

NB stands for next best and is generally used for the tipster's second choice behind their NAP on horse racing betting sites. For example, a tipster might nominate a horse at 6/1 as their NAP and another at 4/1 as their NB after rating both highly.

A fictional tip might read: "Kempton 3.20 – Silver Arrow, 7/2 NAP. The 5yo has the form to win after a strong finish last time."

Some publications also track tipsters' NAP strike rates over a season, giving readers a profit and loss record for all types of horse racing bets from that particular expert.

A NAP is an opinion, not a guarantee. Even a tipster's most confident selection can lose, because horse racing outcomes are unpredictable and a strong selection can be beaten for numerous reasons.

NAPs can instead be treated as one input alongside a horse's form, ground conditions, market moves in the prices and your own assessment. A NAP should not automatically become a bet at bookmakers or betting apps simply because it has been given that label.

These terms are commonly seen in horse racing coverage, but they can also appear when tipsters discuss other sports.

A NAP is a tipster's strongest selection from their daily bets or tips. It is usually associated with horse racing and represents the pick they have the most confidence in, based on their own assessment. It remains an opinion and is not an official prediction or guarantee of success.

The NAP is decided by the individual tipster making the selections. Newspapers, websites and betting services may employ different tipsters, each with their own methods for assessing races. One person's NAP can therefore be different from another tipster's strongest selection for the same race.
