- First choice
- The horse Horse Oracle gives the best chance of winning. It is an estimate, not a promise.
- Win estimate
- How often Horse Oracle expects that horse to win a race like this one. 31% is about 1 in 3.
- Morning line (ML)
- The track's own estimate of each horse's odds, set before race day. It is not the live odds.
- Early speed
- Horses that usually race at or near the front early on.
- Front, close up, back
- Where Horse Oracle expects each horse to be early in the race: on the lead, just behind it, or towards the rear.
- Speed, stalker, closer
- Horse Oracle's read of how each horse usually runs: near the lead, just behind it, or coming from the back.
- Contested lead
- Three or more speed horses. They can tire each other out, which helps the horses behind them.
- Two-horse duel
- Two speed horses. Watch the turn for which one gives way first.
- Lone speed
- One speed horse. The question is whether it can hold on alone in the stretch.
- No early speed
- No horse that usually leads. Expect a slow start and a late sprint.
- First-time starter
- A horse running its first race. With no race record, estimates rest on workouts and breeding, so they are less certain.
- Chute
- A straight extension of the track where some races start, so the horses run straight before the first turn.
- Furlong
- An eighth of a mile, about 201 metres.
- Claiming race
- Every horse in it can be bought for the stated price. The price sets the level of the race.
- Maiden
- A horse that has not won a race yet.
- Scratched
- Taken out of the race after entries closed.
