1.又一例经典防守
OPP精确开叫2C,最后3N结束,又我搭档老徐首攻8,过程如下:

我坐西家,同伴首攻8,庄家没有4张(叫牌中2问叫没有叫2),同伴肯定攻出4张套的助攻,我需要要猜同伴是1087x还是87xx;明手放小,我J,庄家A吃住,动AKX到我手,同伴在第三张上垫小2(这牌有点模糊!!),我提K看看,庄家垫10,同伴垫7(我们打小欢迎信号);9没见而庄家居然垫10,想干什么?可以确定同伴没有9,庄家在玩把戏,其实有点弄巧成拙,如果垫9,我还也可能打同伴1087x,但是同伴信号也明显,只是可能出错。现在毅然放弃回J,庄家盖K,彻底断桥,眼睁睁看着3个赢墩无法兑现,痛苦中,后面防守简单了,打K我再仍然防止暗手10XX再进手,然后D投入明手,庄家投降-3.
后续分析,这牌换南家打3N几乎铁牌,通常不可能首攻S!!开室我们队友也是3N首攻d,结果+1.另外我搭档老徐稍微有点疏忽,第三张C应该垫h7断绝我回H希望,当然当打出SJ,防守已经走上平坦大道。

1.首攻:通常来说,4张小攻长2,如果是双连张是否攻顶张呢?就这幅牌而言8比7更利于pd进行判断;
2.h分布的判断:叫牌显示庄家最多3张,庄家的处理跟10明显是画蛇添足,但是他跟9呢?10在同伴哪里吗?
如果他是A9双(3)张,第一墩会怎么处理?显然是跳Q而不是放小,这里不管庄跟10还是9都很容易判断出庄家是A109;
3.hK后需要停下来计算一下庄家的赢敦以及防守的宕墩在哪里?
如果pd有sA,回h简单宕1,回s能断桥(叫牌表明庄家s最多2张),显然选择回s;
如果pd有sK,回h直接送成,回s庄只能吃住sA,残局需要打对分布才能mk;
不管怎么分布,显然这个时候应该回s而不是h。
