Hi there fellow bridge players.

In contract bridge, if the opposition opens one diamond and we don't ask what the one diamond means, is the opener's partner allowed to offer information about what the one diamond call means without us asking? In our situation, opener's partner said "That means at least four diamonds". I said she is not allowed to offer information unless we ask. An argument quickly ensued. I would appreciate it if someone could set us straight.

The short answer, NO you should not be offering explanations of your partners call unless asked.
1D showing 4 does not require an alert or an announcement.


I'll leave the long answer to mycroft

The intermediate answer includes that in several jurisdictions, 1D showing 4+ does require an announcement
Perhaps not in ACBL.

In short, you should know and respect your regulations about alerts and announcements, in addition to the Laws of duplicate bridge which do not dictate such things.

Alert regulations vary according to the regulating authority. In some jurisdictions, a player adding commentary like this would be UI and likely draw the ire of the TD: in others it is not only allowed but also required. You should also be careful in dressing down your opponents for some perceived breach of regulations. If this is indeed a RA where announcements are required, your actions might easily be interpreted as anti-social and result in a Zero Tolerance penalty. Rather than get in an argument over a regulation you yourself admit you do not actually know, why did you not call the TD and get an actual answer to your question? That is the point that I think you need to be set straight on more than anything else.
