Today's GB - Chepstow Horse Racing Picks

Apprentice

A new jockey who has not ridden a certain number of winners in a specified time period.

Minus Pool

A pari-mutuel pool – typically a show pool - where one horse is so heavily bet that after deductions there is not enough money left to cover the prescribed minimum on each bet.

Claiming Race

A race in which horses are entered for a certain price, or claiming tag, which is also their sales price. An owner can claim any horse entered for the tag before the race begins, and owns them as soon as the gates open.
