Thank you all for responding. I also direct, and my concern is for less experienced players.They have only the opps' cc for guidance. My suggestion is that bids deviating from the cc be self-alerted. I realize there is no way to get all agreements on the cc. I carry this to extremes : playing support X, I will self-alert my pass on 1C (p) 1S (2H) pass. Also , all responses to Jacoby 2N ( 1S 2N 4S - I have a minimum with no singleton or void ). My goal is for the opponents to know as much about my bids as my partner does. Newer players don't know which question to ask, especially about negative inferences that my partner will know.
