A

Accumulator (Acca) A single bet combining four or more selections from different events. All selections must win for the accumulator to pay out. The odds multiply together. Popular for high potential payouts. But they carry significant risk. The bookmaker margin compounds with each selection. Learn the right way to approach them in our guide to Strategic Bet Builders and Accumulators.

Across the Card A series of bets on horse racing. You select a horse in every race at a meeting.

All-Weather (A/W) An artificial racing surface. Examples include Polytrack, Tapeta, and Fibresand. Designed for horse racing when traditional turf courses might be unraceable. Used during adverse weather conditions.

Allowance In horse racing, a weight reduction given to a horse. Compensates for a certain factor. The most common is an apprentice allowance. A horse ridden by an inexperienced jockey carries less weight.

Also Ran A horse or greyhound that finishes a race. But doesn’t finish in a prize-money position. In other words, “unplaced”.

Ante-Post A bet placed on a future event. At least a day in advance. Ante-post markets for major festivals like Cheltenham can offer much larger odds. The major risk? Your stake is usually lost if your selection doesn’t run. Becomes a non-runner.

Arbitrage Betting (Arbing) Placing bets on all possible outcomes across different bookmakers. Guarantees a small, risk-free profit. Possible due to discrepancies in odds offered. Bookmakers strongly disapprove of this. They’ll quickly restrict or close suspected “arbers'” accounts.

A team with a -1.5 handicap must win by two goals or more. Key tool for finding value on heavy favourites. Discover its strategic use in our Guide to Specialised Bets.

Combining positively correlated events. Events where one outcome makes others more likely. Learn this expert-level skill in our guide to Strategic Bet Builders.

Betting Exchange A platform for peer-to-peer betting. Punters bet against each other. Not against a traditional bookmaker. Users can “back” a selection to win. Or “lay” a selection to lose.
