Hi all, In France, your question is a sort of taboo one ! We have here a college of "Ayatollah's" which fight against they considere as an anatheme : opening a strong no-trump with a five card major. In fact, it could be a good move and I don't see any reasons to prohibate a such action. I think it is a partnership decision to say "never" or "sometimes". They are afraid to miss the major game in a 5-3 fit ? Many conventions allow a perfect hand description, for instance : 1NT-2C 2x-2NT=GF relay for shortness (less than three) 3x = shortness (3C=S, 3D=H, 3H=4333, 3S=D,3NT=C)* * a minor shortness imply the knowledge of the complete distribution : four H and a club shortness imply 3442 ; no major and a D shortness imply 3352,... On a major shortness, it's possible to relay again for the minor length : T, D, 44 1NT-2C-2S-2NT-3D(H shortness)-3H-3S=club length, so 4234. Michel
