Today's GB - Chester Horse Racing Picks

Fractions

The times recorded during the race; with timing starting just past the gate or when the gates open, then parroted for the quarter, half, three-quarters etc. Used as an indication of ability and speed.

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.

Underlay

A horse that is going off at lower odds than it deserves based on performance.
