Bidding Standard American, and opening a "strong" two clubs (typically 22 HCPs and a six card suit), I like to hear responses of 2 diamonds (0-8 points, no more than game interest), or 2NT (9+ plus points, possible slam interest).
I don't want to hear other responses (2 hearts, 2 spades, 3 clubs, 3 diamonds) unless the responder has at least six of them headed by something like KQJ (or better). The reasons are because 1) I've "advertised" such a good 6 card suit myself, and 2) with 22 points, I don't want partner bidding "my" suit and exposing my hand as dummy. (It's unlikely that we'll both have the same 6 card suit, which is why I allow this exception.)
Am I wrong to ask my partners to limit their responses to 2 diamonds and 2NT? Or are there other viable responses to my 2 Club opening?
