Hello is a bridge convention used for intervention over an opponent's 1NT opening. It allows for all one- and two-suited hands to be shown, and - for one suited hands - retains the ability to transfer. It features the following calls: *Double is for penalty *2 shows diamonds or a major-minor two suiter. Responder transfers to 2 which is either passed or advanced (diamond suit) or a major is bid (2 suiter, unspecified minor) *2 is a transfer to hearts *2 shows both majors (responder may pass or adjust to 2) *2 shows spades (natural bid) *2NT is a transfer to clubs *3 shows both minors (responder may pass or adjust to 3) *3 shows both majors with massive playing strength (responder takes a preference to 3 or 3, or jumps to 4 or 4 with supporting values) By design, in many cases, the advancer will become declarer, thus placing the strong 1NT hand on opening lead. The convention is named for two of its inventors, Jerry Helms and Bill Lohmann. ==References== * Helms, Jerry (1996) ''(Helms to Hello )'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hello convention」の詳細全文を読む スポンサード リンク
