I have found that the opener usually knows where he would like to be. His partner is only giving him info to help him....thus you will be better informed as to his points, how far you normally could go and his suit. Which is more in one bid than a 2D waiting or normal step response would give you. ALL in one bid... Yes, like anything, it may have a few drawbacks, but in the long run, My partner and I have averaged best boards the majority of times. And thats what you want in tournaments..the best.. try it for a while..you may find you like it.. ted
