The hesitation makes clear that South is considering to call, but it's not obvious for N what. But their agreements make it impossible for S to bid a minor at the 2-level, which makes it more probable that S has a minor suit than 2 minors or majors, or a major and a minor or a major. Without that knowledge N would probably start with either spades or diamonds, unless he's one of ggwhiz's locals, so a club start could be suggested by the UI. I just forget about the 'demonstrably', bcause I've no idea how that demonstration works.

West wrote me a long letter explaining why South must have a heart suit, because any hand that was considering bidding a minor at the three level would have opened with a pre-empt.

We decided that nothing could have been demonstrably suggested over anything else by the hesitation, so we let the result stand.

I agree with this, he might also have been trying to work out what hand could meet his agreement on a double
