Rebids after a Two Club Opener
Responder's initial bid will indicate the possibility of game and the presence of any decent suit or No Trump stopper in Responder's hand.
Opener should then show his suit, or No Trump distribution, and responder will support, deny suit support with a No Trump call, or even pass if Two Hearts was his original response.
A jump to 4 NT by either partner is Blackwood, with the Blackwood bidder in charge.
Stronger Than Two No Trump Range. With a No Trump hand and more than the 20 or 21 HCP allowed for a Two Notrump opener, open Two Clubs and then bid Notrump at your next turn. This is then the same as the traditional Two Notrump opener of about 22 - 24 HCP.
