1♠ - 2NT 4♦ - 4♥ 5♣ - 5♦ 5♠ 1S = Standard 5 card major 2NT = forcing major raise 4D = 5 carder suit. Could be min hand 4H = control showing, either first round or second round 5C = club control, first or second 5D = diamond control, could be Queen but not shortness I guess at this point of time, 6C should show club void and deny a heart control. 5H shows heart control. I am wondering what 5S means? Is it "I have nothing else" or does it make sense for 5S to ask for trump quality here? What should 5NT be and what should a jump to 6S show?
