hi,我第1轮不会加叫同伴的花色,同伴可能只有4张,低限平均牌,方片没挡张,我也不愿意再叫2NT(有人约定2NT垃圾箱,表示一手垃圾牌),我会再叫2,2并不承诺6张黑桃

我愿意再叫2nt,因为加叫3c条件是:4张支持,或3张含一大。而本手牌低限,软实力多,5332均型,还是老实地叫回2nt静观同伴的再叫性描述为好。而再叫2s不作6张处理,需要约定:表明没有可叫的4张花色,5332均型,等待同伴再叫。

按哈代上册所说,开叫人再叫2NT保证未叫2门均有止张,且通常为平均牌型(如5-3-3-2),所以我想我会叫2

如果反过来2S承诺6张的话,那么2NT不能可能保证有止张了,到底前者还是后者的信息通常更为重要呢?

第一轮是不加叫的,因为低花二盖一可能只有4张甚至3张;哈代上册中加叫3C的条件是:要么有4张支持,要么牌力尚可(14+)且有3张带一大牌支持。

我会叫2S,一个变通的叫法是2NT,如果3NT是最佳定约的话,这手牌适合坐庄;

我选择2NT,先把牌型描述给搭档好了,可D确实太弱

2已经建立了FG进程,所以叫2NT是本手,是正确的描述了这手牌的情况(点力低限和均型牌全描述清楚了)。
