System: Course winners at the foot of a handicap chase

Mechanism and rationale

A proven winner, lightly weighted in a handicap chase, back at a course it has won at.

The rule

is_handicap = 1 AND race_type = 'Chase' AND prior_wins >= 2 AND weight_rank_low <= 2 AND prior_course_wins >= 1

Reads: is_handicap, race_type, prior_wins, weight_rank_low, prior_course_wins
