I partition strong hands into 1C or 1D. This steps my NT ladder AND which 2-suiters are in 1C, which in 1D, which left to open 1H or 1S and jump shift. So, What does the rest of your system handle? Remainder into 1C. This partition allows Dbl to suggest misfit M if 2-suiter M-m expected. Bid has tolerance+ for expected M. Eg. 1C <2H> X = don't fit Spades; 3m =m-stuff +S-Hx(+) Don't you have a reserved response for S-KQJxxx, m-KQJxxx? Similar near positives? One message, this suit. At least for Majors? a 2M response?
