Rule 4 deduction - Horses
A rule 4 deduction applies if one or more horses do not run after you have placed your bet. In such cases, your odds are adjusted due to the fact that one or more expected competitors do not participate in the race which causes an increase in your chances to win. (link: rule 4 deductions)
