On BBO, When an opponent explains a bid, and the explanation isn’t sufficient information, suggest: Add a check box to the explanation labeled: “Tell me more” and a line to type what you are asking for. Repeat the box after he gives more information in case it is still not sufficient. This happened: The auction proceeded: 1 Club by partner, 2 Diamonds by the Opponent (no explanation). When I asked, he replied “Diamonds” This yahoo had a strong jump overcall with a side 4 card heart suit for his bid. I should have asked for the director after the hand was over, but I didn’t.
