just finished an online tournament. first bid was 3h(alert),description "barrage". after bidding and before I made the opening lead I asked the meaning of the alert. the opp was slow in responding, so I called the director. just as director came on, opp replied " we go o".I asked what "o" meant. dir privately responded that "I should read more on bridge" do I misunderstand alerts? I expected a clear description of the alert
