I dont understand two things; why dont u trust u prd, who else r u going to trust after all prd is the only guy in the table that even pretends to be on u side.
I trust my partner but not if we haven't discussed the system and I don't have a good reason to suspect which type of checkback he uses. Moreover, I had a good idea of his level and I know that it might not be clear to him which bids are forcing after 2♣ nmf.
