Minibridge is a simplified form of the complex card game Contract Bridge designed to expose newcomers to declarer and defensive playing techniques without the burden of learning a detailed bridge bidding system. The game was first introduced in France and the Netherlands in the 1990s. The variant described in this article is the one advertised by the English Bridge Union for use in primary schools as a way to improve pupils' performance in mathematics. Like other forms of bridge, Minibridge is played by four players in fixed partnerships, sitting crosswise. A full pack of 52 cards is dealt to the players, each receiving 13 cards. As in contract bridge, it is then decided which player becomes ''declarer'', but a key innovation of Minibridge is that this decision is taken out of the players' hands. Declarer's partner then lays open their hand, and declarer announces a contract. This is a trump suit or ''no trumps'', together with an undertaking to win more than half the tricks (''partscore'') or even to win 100 trick points or more (''game''). The remainder of the game is very similar to contract bridge. In particular, declarer's partner becomes ''dummy'' (i.e., declarer plays both hands). ==Bidding== Each player adds all high-card points in their hand and announces the result. The partnership with more combined high-card points then plays the hand. If both partnerships have the same number of high-card points (i.e., 20 each), the hand is redealt. Of this partnership, the partner with more high-card points becomes the declarer. The partner with fewer high-card points becomes the dummy: this player's hand is put face up on the table, and is played by declarer in addition to declarer's own hand. If both partners have the same number of high-card points, the one who states his high-card point count first is the declarer. Having consulted dummy's hand, declarer decides the denomination (i.e., the trump suit, if any), and whether to be in game or a partscore. For partscore, declarer needs to win 7 tricks in order to score. For game, 9–11 tricks are necessary, depending on the denomination. Declarer's decision is often based on a few simple guidelines: # Two balanced hands usually require about 25 high-card points to score a game bonus. # With eight cards (or more) in either Major suit (a "Golden Fit"), that suit should usually be the trump suit. # Without a "Golden Fit" in a Major suit, play notrump. 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「Minibridge」の詳細全文を読む スポンサード リンク
