Arb Cruncher betting glossary



Accumulator     A cumulative bet where the bettor designates a selection in several races or events and bets on the first one; if he wins, the winnings become his bet on the next; and so on (also see fold bets).
Across the Board     Where (particularly US horse racing) win, place and show pools are offered, this is a bet of equal stakes on each outcome.
Action     A bet or wager of any kind is deemed Action if valid. Different rules apply in different sports in determining if a bet is action or no action (e.g. baseball bets are action when the game gets beyond 4½ innings).
Ajax     UK slang term for betting tax, now abolished.
Also Ran     Any selection not finishing 1st, 2nd, 3rd or 4th in a race or event.
Ante-Post     Ante-post prices are those on major sporting events, usually prior to the day of the event itself. In return for the chance of better odds, punters risk the fact that stakes are not returned if their selection pulls out.
Any To Come (ATC)     Term used to describe when the whole or part of returns from one wager are automatically reinvested  on a subsequent bet.
Arbitrage     An arbitrage is available when pricing discrepancies between betting sites allow punters to place bets that will yield a guaranteed risk-free profit. There are two types of arbitrage in sports betting - Back/Back arbs and Back/Lay arbs. Not to be confused with trading, where punters trade on anticipated price movements, instead of current price differentials.


Back     To bet that a selection will win. On Betfair this is done by betting in the blue box. The opposite of lay.
Back/Back Arb     An arbitrage opportunity whereby you can back all selections in an underround book for a guaranteed profit, whichever selection wins. Also known as book arbitrage.
Back/Lay     An Arb Cruncher betting calculator for exploiting Back/Lay arbs or for equalising your trading profits.
Back/Lay Arb     An arbitrage opportunity whereby you can back and lay the same selection for a guaranteed profit, whatever happens to the selection. Very common in the early rounds of some European cup competitions when rumours of fixed matches send prices plunging on the exchanges but coupon prices remain relatively unchanged. Strictly speaking, both prices must be concurrently available for it to be considered a risk-free arb. If you back a selection in the expectation of a shortening of it price, you are trading.
Banker     A punter's strong selection or "sure thing". An almost guaranteed winner, as in a Lock. Also, in permutation bets the banker is a selection that must win to guarantee any returns.
Bar     Those runners in a race not quoted with a price during early betting shows. The bar price is the minimum odds for any of those selections not quoted.
Baseball (US)     In horse racing, a Daily double is a play in which a bettor couples a horse in one race with all horses in the other (also known as "wheeling").

Betting Exchange     A person-to-person (P2P) betting site where punters can bet directly with each other at more competitive prices than those offered by traditional bookmakers. You can either place a bet (back), or act like a bookmaker and accept someone else's bet (lay). The exchange uses sophisticated market-driven trading software to match punters' bets (orders), and deducts a small commission from the net winnings of the bet winner.
Bingo     Social betting games incorporate the appeal of a highly interactive player base, with the opportunities to profit off randomly generated outcomes. One such betting game is bingo. The objective of this game is to complete lines, patterns or full cards in expectation of winning the bingo pot on offer. Players are able to partake in speed bingo games (30 ball bingo), 75 ball bingo, 80 ball bingo and 90 ball 'bingo'. The latter category allows for betting selections on 1 line, 2 lines or a Full House. Odds and probabilities of betting in bingo games are dependent on several factors. These include the number of players actively participating in the games, and the number of bingo cards purchased by the player. Typically the more expensive bingo cards yield greater payouts for lucky players.
Blind Bet     A bet made by a racetrack bookmaker to draw other bookmakers' attention away from his sizeable betting on another horse- and thus to avoid a shortening of the odds on the other horse.
Book     This is the sum of the probabilities reflected by the prices set for all selections in an event. Mathematically speaking the total probabilities of any event is always 100%. However, bookmakers set their prices so that their probabilities add up to over 100%, with the amount over 100% representing their profit. An arbitrage opportunity therefore arises when the best available prices from several bookmakers creates a Book percentage of less than 100% ("underround"). Conversely, you can profitably lay an event if its book value is over 100% ("overround").
