IMP双有,南做庄3NT:
42
AJ73
9852
J43
AK7
T98
AK43
AK2
叫牌过程很简单:2NT-3C-3D-3NT (东西方未插叫)
首攻S6(长四),东家出SJ,庄家忍让一轮。东续攻S9,庄家赢进,出H8,西家和明手
放小,东家HK吃到,再打黑桃拱出庄家最后一个止张。庄家接着出H10飞,再出红心,
西家HQ,明手HA。这样庄家总共获得两墩黑桃,三墩红心,再加DAK,CAK,共计9墩完
成定约。
现在问题来了:双方哪里打错了?顺便说一下,对错不能只看结果。 | s*******y 发帖数: 946 | 2 红心上,第2轮,西家应该直接上Q吧? 庄家三墩红心拿的太容易了。 | i****e 发帖数: 642 | 3 From the bidding and the lead, it is likely LHO holds long spades, or 4-4.
Based on this assumption, it may be better for declare to check diamonds
before playing hearts.
As the real play goes, after HT wins, declarer already has two tricks in
each suit. He should check whether diamonds break before playing third
hearts. Otherwise when LHO follows Hx rather than HQ, he will have a
headache to choose A or J, either of which can be wrong.
For defense, LHO can jump HQ at first round of H play, knowing it won't be
stupid since declarer has 3 hearts or less. Declarer has to guess what LHO
holding is (only HQ or both H KQ). The better play, depending on how he
guesses the LHO's bridge skill, may be to win HA, play another H to hand (
opps will duck for sure), and then check diamonds.

| b***y 发帖数: 2804 | 4 这副牌从防守方来说,主要失误在于西家第一轮红心没扑HQ。西家可能秉承了“二手低
”的原则,但每副牌的具体情况不同,需要区别对待。这手牌是“二手高”的教科书实
例。如果庄家有HK,这张Q总是死的。最关键的是,明手没有其它进张。
实战中,在西家已经放小之后,防守也并非全盘皆输。想一下,东家如果平静地也跟小
,庄家后面会怎么打?如果庄家转而测试方块,会发现东家持四张方块QJxx。庄家再打
红心,西家放Q,庄家就有得猜了,多半猜错甚至宕二。 |
