How strong can 3C be?
2C with a major suit rebid promises strong clubs, which I
would take as at least 5 topped by the A or K and 2 other
honors. Can "good" clubs here be weaker than the "strong"
clubs in the immediate 2C? I don't know. Sometimes EK's
"good" seems to mean "strong:", but in other cases, I'm
not so sure. Anyhow, if "good" can be a weaker suit than
"strong", responder can have 12+ HCP.
Emphasis on honors it the suit of the jump. Why?
Why not? With a 5c non-descript M, responder can
force with 2M, perhaps taking a stab at 3NT over 3C with
10+ HCP. With anything else non-descript, responder can
force with 2D. I think, in general, second round jumps by
responder should be purish, showing a concentration of
strength in the suit(s) bid by responder and at least mild
slam intent.
