What is the difference? 3NT shows a hand, which will have a reasonable chance of making 3NT oppossite an avg. hand. If you hold a strong NT, say 16HCP, assume 8HCP for the weak, than you have 16HCP missing, on average your partner will hold 8HCP, not enough. If you have 20HCP, you have 12HCP missing, on average your partner will hold 6HCP, enough. With kind regards Marlowe You're saying there's no difference between A Kx Qxx AKQJxxx and the given hand?
