Arbing – akamatched betting- means taking advantage of odds variation between bookmakers to make a profit on an event regardless of its outcome.

It involves simultaneously betting on every outcome of an event, while calculating that, whatever happens, the combined bets willguarantee you a profit.

The key to arbing is finding two bookmakers offering significantlydifferent odds. This could be on an event with two possible outcomes (win or lose), such as tennis, or an event with three possible outcomes (win, lose, or draw), such as football.

Arbing requires large stakes, patience and a cool head. The typical return on investment is between 2% and 5%, but it has many advocates who have used it to make decent profits.

Opportunities for arbing occur in a wide range of different sports. Do your research to learn about the best places for arbing opportunities.

Fluctuations in odds mean these only stay available for short periods, so a key to successful arbing is monitoring the betting markets and, when the moment comes,quickly taking advantageof odds that offer guaranteed profits.

Take a tennis match. Bookmaker A is offering odds of [1.6] on Rafal Nadal winning, and [3.9] on Roger Federer winning. Bookmaker B is offering longer odds of [1.9] on Nadal, but shorter odds of [2.9] on Federer.

You place a200 beton Nadal at Bookmaker B. You then bet on Federer at Bookmaker A, and calculate your stake by multiplying 200 by the result of 1.6/3.9 (your shorter odds divided by your longer odds).

So in this case, 200 x (1.6/3.9) = 82. Your total stake across both bets is 282.

If Nadal wins, you stand to claim winnings of 380 from Bookmaker B – a98 profitacross all your bets.

If Federer wins your 82 stake wins you 319.80 – a profit of37.80across both bets.

Arbing is entirelylegal. All you are doing is taking advantage of the differences that occur in the market. In fact, the scenarios in which arbing is possible are deliberately created by bookmakers, as they have tobalance their books.

Some betting companies, however, see arbing as athreatto their profit margins and frown upon the practice. They are entitled to make their own call on whether to suspend customers from their books.

For this reason,diversityis key to any arbers approach, so shop around and remember that being limited or suspended from one bookmaker doesnt mean the end of the road.

Keepdetailed recordsof your transactions. The large funds required to generate small profits from arbing mean that it is important tomaintain disciplineand consistency in your approach.

As well as carrying out a good deal of research, and being organised with access to several different sportsbooks, it is wise to takeprecautions: only bet in one currency, never bet to the maximum stake limit and avoiding long-term arbs (anything over a week is inadvisable).
