My partner and I open 2 diamonds showing 18 or 19 High Card Points. It has no other meaning and does not describe shape. We alert it as such. The partner responds withi6 point steps to show his./her High Card Point Count. 2H shows 0-6, 2S shows 7-12 and 2NT shows 13+ HCP. The opener uses this information to determine whether to proceed to game or explore slam. The 2H response says proceed with caution, 2S says game pointss are there, 2NT says explore slam. If the responder bids H or S in response to the 2D opener, the opner then bids best suit looking for a fit, or 2NT if no good five card suit. If opener bids 2NT as second bid, responder treats it as though it was an opening NT bid and bids stamen or transfer, or in the case of a very weak hand, passes at the 2NT level. Either partner might have distributional points to add to the HCP already established and push the other partner toward game or slam. I don't know that our system fits any of those named here: Mexican, Flannery, etc.
