The Individual Pairs (IP) is the last bastion for NATwA match play use of the Perimeter Rule. In Pairs and Singles tournaments, consensus is needed (and often reached) to invoke this rule over the old standard off-the-table rule. At the IP its the other way around, altho if Dave is playing, theres sure to be a vociferous discussion between Dave and Sunshine.
So, to rephrase an old commercialif you come to the IP, expect the Perimeter Ruleand dont leave the table without it.
