F
Favourite
The horse or team with the lowest Odds (in essence, the horse or team believed to be the most likely winner).
Fixed Odds
Odds available at a specific price quoted by a bookmaker. These odds may change over time but the odds quoted when you place the bet are secure and do not change. N.b. The actual returns may not always reflect the full value of the odds due to exceptions like the Rule 4 and dead heat rules.
Fold
When preceded by a number, a fold indicates the number of selections in an accumulator. An 8-Fold would be an accumulator with 8 selections, all of which must win for the wager to be successful.
Forecast
Predict the result. Also a type of bet in horse racing where the punter bets on the winner and the second place horse in a specific order.
