Confidence: high
Model: claude-sonnet-4-6
Screened: 2026-04-07T08:09:00Z
Reasoning: If Koepka finishes top 20 at the Masters, he must have made the cut — you cannot finish in the top 20 without making the cut. The reverse does not hold: making the cut does not guarantee a top-20 finish.
Strategy: Buy NO on antecedent + YES on consequent
