For many years I had the honor to co-direct the prestigious Bridge World Master Solver's Club. Every month experts voted on a set of tough problems. The director writes up their answers, assigns scores, and stick in his two cents.
In 2008, I was asked to guest-host this Conventional 2NT response to a weak two-bid that asks opener to show a high card in a side suit if he is not with a minimum preempt feature for Australian Bridge. They have posted the article on-line.
