这是JEC比赛出现的一副牌。问题来了，这牌你心理肯定清楚，你将面对4♥和3nt最后定约的选择！如何定约？

如果打♥有将定约，同伴的♠大牌是没有机会增加赢墩的，相反无将定约时，同伴的♠止张能制造赢墩的。手中已经有7枚赢墩，希望能与同伴配合再取2枚赢墩完成3NT所需的9墩牌。叫3NT吧。
正确的判断来自经验，而经验常常来自错误的判断。

寻找自己的错误才是学习桥牌的唯一进步方法

很难选择。打3NT的好处是手上赢墩7个，同伴S上能取得一个，但C是不是漏的呢？打4H，怕同伴在S上实力偏重。我也许会叫3♦出来，看同伴如何选择。

开室: JEC选择了4♥，4♥S= +420




闭室: jfaria选择了3nt，结果-2 -100



结果相差了11imp。
