What I mean by "no fault of their own" is that Laws are voluntary reading, there is no requirement to understand the Laws other than the rudimentary mechanics, following suit and making sufficient bids. I'm beginning to believe that what players learn about UI problems is that it is minor distraction, the NOS are considered guilty and the OS receive a "stern warning". Penalties won't happen at any club game or sectional tournament and by the time you get to the tournament level where procedural or disciplinary penalties may be used the players have no history, the Director encounters this for the first time, no PP, DP I asked a long time bridge player here, have you ever seen any DP or PP? Yes, for mouthing off at the Director. Nothing for UI/MI? No, but boards do get adjusted. Another player told me today of the warning of a penalty when playing in the Blue Ribbon Pairs and they had failed to alert, twice. The player admitted they had 78 pages of agreements and neither of them knew their system.
