正常的叫法是


但高限时,是否可叫2H?

你已经成了从叫方,没有例外,只能2.
你的同伴是主叫方了。

什么是“正常”的叫法?如果用xyz,就叫2D。如果不用xyz就叫2NT(或者3NT):如果2C可以是挺弱的牌,C比S长,南就该叫2NT;否则叫3NT。

题目中明确是“2/1,2C=双路”。

这牌用2H逆叫因为有叫回S的退路,

否则也会有叫乱的危险.

叫2没有例外,这双路的纪律,因为应叫可能是4张+5张弱牌。开叫人只有等待应叫人再叫。

2显示9-10hcp,黑桃五张,开叫方(2443牌型均衡)与应叫方合计的牌力不足以进局,所以PASS。打52配的部分定约。

如果开叫方块保证张数(比如约定5542),双套配合,扣叫4,进行Slam try。
如果开叫方块不保证张数(比如约定5533),则叫4,是否继续Slam try,由同伴决定。

看来“双路”就是xyz?如果是xyz,就只能叫2D。

双路是MTWS(Improved 2 Way Checkback Stayman),双路斯台曼的简称。

2S争叫是基于6张S。得到同伴的支持后(同伴的3S只是竟叫,都不是成局邀请),可进局。试贯太过分,同伴应该知道你的C短,也许有几张好C,等着惩罚呢(如果你的2S是凭牌力)。
满贯需要同伴有完美的牌:SAK(x), DAQxxx(或者SKJ(x),HAx(x),DAQxx)。同伴这么好的牌,不会只叫3S。

同伴是开叫方,点力集中在黑桃和方块套是可能的[比如SAKx, DAQxxx(或者SKxxx,HAxx,DAQxx)],Just try,并不一定非要到贯。

3S不一定逼局,要看同伴间的约定。

这个牌,如果同伴的H没有太多废点,有D的控制(或者HAK加DA,再有S的支持),有贯。如果同伴的S短,大牌在H,局都没有。4S也是一个不错的选择。

扣叫2C也可以考虑,但2C通常被理解为对H的支持。如果同伴在2C后叫4H(“接受”邀请),你就面临困难,只好在叫4S。但愿同伴不要理解为满贯(H配合)试探。

1先逼叫一轮。同伴再叫2或2逆叫(2的可能性很小)后再跳叫4,同伴叫2NT跳叫4
