Frequently Asked Questions
What's a forecast bet?
A forecast (the US calls it an exacta) backs which two horses finish 1st and 2nd. A straight forecast needs the exact order; a reverse forecast covers both orders for double the stake.
Forecast vs each-way — what's the difference?
Each-way is two separate bets (win and place) on one horse. A forecast is one bet tying together the finishing order of two horses. Forecasts pay far more but win less often.
Straight or reverse?
Go straight if you’re confident which horse wins. Go reverse if you expect two horses to take 1st and 2nd but aren’t sure of the order — double the stake, both orders covered.
Do forecast odds equal the multiplied book odds?
Most UK bookmakers pay the Computer Straight Forecast (CSF) dividend declared by Tote/SP, not straight multiplied odds. Multiplying is a handy estimate, but real payouts can shift ±10-20% depending on the field-strength formula.
