Quite often, the declaring side in an actively ethical partnership will volunteer such information before the opening lead is made. Active ethics enables players to compete on equal terms. In addition, the actively ethical player contributes to the enjoyment of all players by continuously striving to maintain a courteous attitude toward both his opponents and his partner and by avoiding any behavior that would make anyone uncomfortable. These social attributes are vital to the game of bridge and duplicate bridge. SLOW PLAY Failure to finish on time can do a great deal to chase players away from the game and is extremely distressing to waiting players.
Bridge is a timed event.
If a pair takes more than their share of the allotted time for each round, they are inconveniencing their fellow competitors as well as gaining an unfair advantage over them. When a pair has fallen behind it is incumbent on them to make up the time lost as quickly as possible - whether at fault or not. The actively ethical player makes a concerted effort to catch up when they have fallen behind, regardless of the reason for their lateness. All players are expected to develop this good habit. Additionally players should be available to start each subsequent round promptly, avoiding wherever possible being late to a table for non-bridge reasons.
