南家开叫，过程如下：
S W N E
1H X 2NT* P
3C* P 4H AP
2NT = 4+张红心支持，邀叫或更好
3C = 低限
你首攻CK，明手摊牌：
AJ76
A876
J6
A87
Q832
2
KQT93
KQJ
庄家第一墩明手出CA，同伴C2，庄家跟C6。明手小方块，同伴D5，庄家DA。然后再出D2
，你DQ赢，同伴垫C3。现在你怎么防守？ |

发帖数: 20570 | 2 Declarer shows 5-5 in H/D.
Partner shows 6 clubs(because the second C shows the count and declarer is
unlikely to hold 3 small clubs).
Also, partner didn't pitch S, so he's likely to hold SK.
So the shape is clear now, declarer holds 2-5-5-1 shape. Suppose declarer
holds: xx KQJTx AJxxx x
you need to lead trumps now. Later, partner can overruff dummy and play
another H to defeat it.if you play C, declarer can ruff D with HA, ruff C,
ruff D with H8, partner can overruff, and play H. declarer can ruff D with
H7. that's 5H, 2 H ruffs, SA, DA, CA, ten tricksx

发帖数: 642 | 3 This one seems relatively easy. South has 2551 or 1552 shape. We should
prevent dummy from ruffing 3 Ds. So now return trump. Pd will hold his 9 for
overruff, and then he will return another trump. We end up with 1 black
suit winner, and 3 D winner (including 1 overruff). |

这副牌出现在最近一次荷兰与瑞典女队的交锋中。两桌都叫到4H，都是西家首攻，前三
墩都一样。其中一桌西家在DQ得墩后机械地继续CQ和CJ，此后定约无法击宕；庄家将吃
方块时东家可以超吃一次并且回将牌，但庄家总是可以由明手将吃两墩，加上手里五墩
将牌，以及边花三个A，总共拿到10墩牌。
另一桌西家DQ之后经过思考，回了一张红心，东家机警地放小，此后在明手将吃方块时
用H9超将吃，再回将牌，最终庄家只有9墩牌。 |

发帖数: 2804 | 6 对于本期题目"Kill Point"稍微解释一下。有位桥牌大师说过如下一番话：My belief
is that on almost every bridge hand there is a point of time when the action
of a bridge player is decisive for the fate of the contract. The spotlight
is on him or her. What he or she is doing the rest of the time is not
decisive. I call that point the 'kill point'.
绝大部分的kill point，其实都是很稀松平常的，比方这副牌，正确的防守不难找到，
只需简单数数庄家的赢墩就可以了。但是有些专业牌手也没有搞对。问题就在于，没有
人会提醒你：注意哦，这是一个kill point，多花点时间好好想一下。桥牌是个比赛谁
失误更多的游戏，另一线上有朋友就提到，99%的牌都是无趣的。但是这类kill point
就藏在看似无趣的情形中。人的精力有限，不可能每墩牌都集中全部注意力，这个时候
就看牌感，所谓牌感好的，就是对这类kill point有感觉的，能够把精力花在刀口上。 |
