If opponents did announce "Precision", as they would before any serious 
match, then 1N would be assumed to be less than 16 HCP. Hence, arguably, 
it doesn't require an alert. It 's hard to believe that the match was so 
relaxed, that a pair didn't realize their opponents were playing a 
strong club until after the last board. I suppose that the opponent who 
opened 1N on the thirteenth board had a 15 count. If so, perhaps, the 
director should adjust to 4S=.
