Playing Devil's Advocate: Clause (d) says that you can base your actions on information you had before taking cards from the board.

The agreement is only "If partner's dog is named Lucy, we play weak NT."

(b) Each partnership has a duty to make its partnership understandings available to its opponents. The Regulating Authority specifies the manner in which this is done.
