Mini-Roman or Mini-Roman 2 Diamonds is contract bridge convention whereby the opening bid of 2 shows a three suited hand and 11-15 high card points. The convention allows responder to know whether there is game and in a suit contract or notrump. ==Description== An opening bid of 2 shows one of two hands and 11-15 HCP: 4441 or 5440 (the five card suit is usually not a major suit.) The Mini-Roman 2 opening is a forcing bid. Responder has the following options. * 2: Pass or correct and non-forcing; * 2: Pass or correct to 3 and non-forcing; * 2NT: Forcing, asking opener to bid his short suit. * 3 or showing a long suit and interest in game in that suit or notrump if Opener is near the top of the bid. Opener's rebids: * Over 2: pass or bid 2; * Over 2: with hearts, bid 3, pass with spades; * Over 2NT bid the short suit: The advantage to the system is the power of the short suit. The hand lends itself to a cross ruff. 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「Mini-Roman 2 Diamond」の詳細全文を読む スポンサード リンク
