4H。KJx的3张就理解为4张,也同时表明有5张S,让同伴示选高花定约。

因为是IMP的双人赛,就假定4M和3NT都正好mk的牌,这样4M可以多1个IMP,如果3NT+1比4M多10个总分,但IMP相同。当然如果只有3NT,而没有4M,显然输了。

进一步安慰分析,因为存在上面的3中情况,就这一副牌你叫了4H胜算是2:1。假如有101对牌手,第一种情况你的胜率是100%,其他对手是0。第二种情况大家都平了50%。第三种情况你是0,而其他每个对手才10%。

双人赛争取顶分是至关重要的,不惜获得底分。

对双人赛的策略一直不太明白,谢谢3NTMK的解释,这幅牌搭档2H并没否认有3张S,先叫3D如果搭档不能支持S时然后再叫4H可以吗 :)

3,如果同伴叫出了3,那么他的应该是22分布,因为你的大牌用于将吃可能的输张并不能增加赢墩(因为这时将牌会产生将牌的输墩),叫出3NT,的长套赢墩可期。如果同伴叫出了4,那就要做一个salm try,因为这时同伴的不仅仅是54套了。
