The Strong Club System is a set of bidding conventions and agreements used in the game of contract bridge and is based upon an opening bid of 1 as being an artificial forcing bid promising a strong hand.〔(【引用サイトリンク】first=Claire )〕 The strong 1 opening is assigned a minimum strength promising 16 or more high card points. All other bids would therefore be limited to a maximum of 15 high card points. There are several variants of the strong club system and all are classified as artificial because the bids are highly codified. ==Strengths and weaknesses== There are two generally acknowledged strengths of the strong club systems: # accuracy in uncontested slam-strength auctions, because the bidding starts at such a low level when opener has a fairly strong hand. # the fact that all other opening bids have their strength capped by the strong club means more accurate judgment and scope for tactical operation both in constructive and competitive bidding. The generally acknowledged weakness of such systems is the fact that the opponents can aggressively overcall the 1 bid to deprive the stronger opponents of their bidding room, and that the loss of the 1 opening bid often causes strain on other opening bids, most often 1 and 2. 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「Strong club system」の詳細全文を読む スポンサード リンク
