The implied probability for Over 1.5 goals is 78.125%. San Marcos de Arica's exceptional form (5 consecutive wins, rank 3) indicates a high likelihood of them scoring, potentially multiple goals. While Curicó Unido's form is poor, their historical H2H record (6 wins, 2 draws, 0 losses at home against San Marcos) suggests they can also contribute or at least concede. Given the strong offensive potential of the away team and the low goal threshold, an estimated real probability of 88% for Over 1.5 goals is justified, yielding a significant value edge of +12.64%. This makes it a low-risk, safe core pick for a double.
