Walsh Diamonds -------------- Over 1C, a 4 card major is ALWAYS shown unless you have a game-forcing hand with a much better holding in diamonds. Thus, you bypass a diamond suit if you have one or you ignore raising partner's clubs and instead show a major. 1C 1D practically denies a major After 1C-1D opener rebids 1 of a major ONLY with an unbalanced hand. Opener's rebid of 1NT may have one or two 4 card majors! 1C 1D 1H guarantees an unbalanced hand. At least 5 clubs and 4 hearts. 1C 1D 1NT may have 1 or 2 four card majors 1C 1D 1NT 2H responder has a game-forcing hand with much better diamonds (say 6 diamonds and 4 hearts).
