Are there any guidelines for responding to a query by Op about your bid? What to do if Op is apparently dissatisfied with your explanation and just doesn't bid on his turn? My example is that I opened 1♦ p 1♥ me 2♦ lots of bids by us ending with p in 6NT. Op asked then about my 1♦bid (before his bid). I responded: "I bid convenient minors, so 3+ ♦. When I rebid ♦, now 5+ ♦." If he had asked then about 2♦, I would have stated minimum opener 13 and 5+♦. But he did not, sat there for a few minutes and then left the table.
