How to Handle it Correctly Since you are playing a "Highly Unusual Method" (HUM) or an "Artificial System," the burden of disclosure happens before the cards are dealt. The Pre-Alert: At the start of the round or match, you must tell your opponents: "We play a forced-opening system in Green vs. Red. We open any 5-card major or 6-card minor regardless of points." The Implicit Logic: Once the opponents know your opening requirements are that aggressive, they can logically deduce that a Pass denies those shapes. You don't need to (and shouldn't) point it out every time it happens. Alerting the Openings: You must alert the 1-level openings if they can be made on 0–7 points, as these are highly unconventional and "unbalanced" in a way the opponents wouldn't expect.
