Weak or Strong NT?: Which Is Best? (Surrey School of Bridge Research Papers)

The strength of 1NT in bridge has long been a point of discussion and fashion. In the US a strong 1NT is ubiquitous but around the world other strengths of 1NT are common. The world's best pair Fantoni and Nunes play a weak 1NT 11-14 non-vulnerable or 12-14 vulnerable but are they right to do so? This large study of historical bridge competitions shows clearly which wins in the very long run.
