开室:



结果:5N+2 +510

评论:来自威尔士的南北家牌手采取:5442体系,即开叫1保证4张,而1开叫保证5张。

闭室:



结果:4S+3 +510


问题是:我们采用5542体系,如何展开呢?

开室:



结果:2W-1 -100


闭室:



结果:2S-2 -100

评论:两桌都定约2,只是方向相反。有时候是允许第三家拿5张好套开叫弱二的,这副牌南家积极过了头,适得其反。
其实保持弱二开叫--6张总体是个不亏的保险开叫。

闭室南家开叫是策略性的,有投机的含义,即是投机,结果也都是得失互见的。

不赞同S持不太合格的D套作2D开叫,这样的2D不具描述性。

这个是好坏2n吧?使用好坏2n需要和pd进行探讨,必须明确什么时候是好坏2n,什么时候是自然意义。这幅牌在pd2h争叫后,放弃正常意义的2n而约定为好坏2n的得失比姑且不论。就这幅牌而言,取得了巨大的成功!开室没有使用好还2n,在2h后明显失去了再叫的资格,其实N继续3d给了他一次补救的机会,3d后这是一手非常适合做竞叫性x的牌。反观N的3d,则多少有点欠考虑,如果西积极的3dx从而叫到4s,他将追悔莫及!在叫3d之前(单看d套足以叫到3d哈),他应该冷静的分析一下(这里建议大家在高阶的低花争叫前都应该分析一下)另外一门高花套的情况。他只有单张sA,而没有人叫s套,s套在哪里?西很可能是双高的牌,但2h后无法主动叫出。分析到这里,你就会发现冷静的pass2h应该是最佳选择,完全没有必要冒着opp高花进局的风险去抢一个部分定约!
总得来说,叫牌过程是多变的。需要根据不同的局面做出调整,在争叫时需要全盘考虑,而不是只盯着自己的牌猛叫,也就是说要有大局观。
