Double-dummy is idealised — the true best play needs all four hands — so read these as tendencies, not verdicts. Leads, declarer play and defence are charged to the player: where a protocol says a pair sat N-S its first name sat North and its second South, E-W the same, and the declarer's seat does the rest. Against par is a pair result, so it stays with the pair.
