Opening bid that does not satisfy rule of 18
Blue Book level 4: "A one-level opening bid in a suit, whether forcing or not, must by agreement show 8+ HCP and, in first and second position, follow the Rule of 18."
I understand this, but what is not clear to me is whether any action should be taken for a one-off instance. Let's say someone opens 1S in first position with something like this:
The opposition get a bad score and call the director. The hand does not satisfy rule of 18 but there is no partnership agreement on the matter, and no previous infringements are known. Is this then considered a psyche with no rectification? Or is rectification automatic?
