1NT redoubled minus
two
Facts
North lost 1000 in
1NT redoubled, and then South called the TD. The double of 1NT was described by
East to North as four cards in a major and five cards in a minor, or strong.
The double of 1NT was described by West to South as 14+ HCP. West's description
was correct. N/S played that if the double of 1NT is for penalties then
redouble asks North to bid 2§, prior
to signing off in his longest suit; if the double of 1NT is two-suited then
redouble is for business, asking North to pass.
The Committee
decided that, had North bid 2§ and
East doubled, West would double South's 2H a majority of the time. So as to do
equity under Law 12C3 they decided to assign a weighted score. The Committee
pointed out that with screens it is desirable to write down the range of a 1NT
opening if there is any possibility at all that it would be misunderstood
otherwise.
