After a Major suit opening, the convention 1 No Trump Forcing is employed and is considered to be forcing for at least one round, if the partner has not previously passed. First responses to a 1 Club opening are considered to be natural. Otherwise the subsequent bidding follows the basics of the Precision bidding system.
