 Opening one notrump (1NT) means 12–14 HCP and a balanced or semi-balanced hand, possibly a singleton with three four-cards suits and can include a five-card major.Opening two in a suit is natural, showing a hand with unbalanced distribution and limited strength.In the first and second seat, two level opening bids denote a two-suited hand that includes at least a five-card suit, or a six-card or longer suit (if that hand is not adequate for a 1NT opening).
