有空门的话,应该不是那么的弱。

缺门的牌应该是好牌,弱2开叫带空门可能会错过和PD的另外一套配合

弱二开叫定性:描述性开叫


对于前两家开叫要求:
1-在前两家不能有空门,以阻碍同伴的其它花色配合。
2-对防守赢墩无要求,允许有两个Ace。
3-对于6-5套分布不在弱二开叫范畴之内,原因是:极容易阻碍同伴的另一花色的配合。
4-Ogust 2nt问叫:回答牌情特征

对于第三家:
1-对前两家开叫要求解除。
2-由于第三家允许拿较好的5张套作弱二开叫(不论牌型),所以近几年时见有专家强烈指出:加叫第三家弱二开叫花色,一定是4张。
3-Ogust 2nt回答单缺花色。

对于第四家:
1-2阶开叫表示11---13p,6张好套。
2-Ogust 2nt回答单缺花色。




以上是本人的愚见,不妥或遗漏处,请您补充。
再次感谢贴主提问。
