这是今天来自BBO转播的现场比赛一副牌:2♣强开叫后,2♥=负应叫,那么当3♣puppet stayman被加倍后,应该如何正确处理呢?

北家pass后,南家不该叫XX,因为pass的理由等于♣无止张,这样南家的半止由于位置缘故,也要视为无止张,这样他接下来再叫3♥,注意是主动叫出手中的四张高花,让持强牌的opp一方做首攻!
开叫人于是会考虑打莫邪森配合,定局4♥.这才是斯台曼被加倍后的正路子。

这样的思路真不是一般人能想出来的,真是好办法!

好!竟然还有这么好的构思,妙!我压根就没想过pass,现在想来pass确是一个好的出路。

北家PASS 3CXX和叫3NT有什么区别呢?
庄位没有变化,不是仍然要下一吗?
是不是想让对方不攻将牌或者还是想让对方逃叫?

没看到首攻C就输5墩将牌?就算不是首攻C,你可以将吃一墩S,还是要多丢一墩。

更为重要的一点是:南家XX并不保证C!类比堪萨斯1nt,是要求开叫人再叫高花,当然,在开叫人对3cx叫pass表示没有C止张时开叫人可以逆用傀儡stm来回答xx。3s=4张h,3h=4张s,4d=4-4高花,3d=3-3高花。如果确有K10xx+的C也是可以pass的。
