还有,第二轮C要垫Sx, 如果庄家在投入CQ前先引Dx到明手的DKQ10,
你得出D8,不能上A/J,这时庄家经受考验了。
如果上DK/Q,你对家CQ上手后回S到你手,你别动S,回H给明手,
明手被投入而且庄家没有回手兑现C,至少下一;
如果他用10飞J,再用DK/Q投入你,就make。
但他在H还有(双飞你或击落)机会的情况下,在实战中很难说就敢用10深飞DJ。 |

w****b 发帖数: 623 | 4 A D lead would break up the endplay in D and. When East gets in 1st time, he
can simply play DJ to knockout the DA. When get in second time, E can cash
trump (so south cannot ruff C) and cash D, and give E a D ruff if the D8's in
south's hand. NS can get no more than 3S, 2C, and 2D. |

g**********y 发帖数: 14569 | 5 To defend N-S 1NT, perhaps spade lead is the killer. After a spade lead, South

w****b 发帖数: 623 | 6 I'm probably wrong here. It looks East can keep leading D and give west a D

Now the D contract by North looks attracting. 8 tricks might be possible --
the best East can do is to lead DK and then DJ, but East will be endplayed
twice then.

c****u 发帖数: 3277 | 8 well, you still don't get my point, why did our team lose the match?
Not because they don't know how to handle very tough problems, just because
they often screw up simple ones. Just like the 4 spades against Poland,
West holds:

SQ983 HKQT DJ5 CAT98

Polish defender cashed DA and DK, partner followed D 2,6
declarer followed D8 and D7.
Yes, declarer did hide his D3, but isn't it a natural switch of C to
play pd for CK? if part |
|
c****u 发帖数: 3277 | 9 第二副,南北有局。
东开叫1S,
我拿了ST7 H973 DAKT743 CK5
你会争叫2D还是pass.
也许多数牌手这里会Pass, 但是我依然
选择了2D,道理是这样的,这个D套是相当好的六张
套,这样受到惩罚的可能性并不是特别大,而2D占据了
对方的1NT和2C两个叫品。应叫人拿相当多的持牌
类型都会有叫牌困难,比如Sxx HAxx Dxxxx CKJxx,
这个牌2H之后很难办。或者Sxx HAxx Dxx CKJxxxx, 这也很
难办。如果你不对对手在早期施加压力,他们的日子会
好过得多。另外,一个好处是同伴不会有多少平衡得压力。
尽管如此,我心里也不是那么坦然,毕竟,偶尔会承担-800
的罚分。西家跳了3S, 并给出混合加叫的提示,也就是大约7-9
点,四张黑桃支持,同伴pass, 东家很快就叫到了4S.
我的首攻很明确,DA, 明手的牌是:
SQ943 HK62 DQJ CT843
同伴跟出D6, 庄家跟D8。
同伴的D6有可能出自D69或者D652,无论如何,我继续拔DK,
同伴跟出D5, 显示D652三张,而D5这里是花色选择,即欢迎
H换攻,而不欢迎C换攻。下 |

if you let your partner win the first round with his D8, would he shift to

I felt these mortals hold sacred opinion about supporting, so I don't feel
they had an 8 card trump fit. And it'll be a long shot for my poor hand,
given that pd had 3H, to have game. If so, I felt we should have something
good in S. And after all, giving up -160, or collect 200 while we have 400
is no big disaster. But getting 500 in this situation has some moral values
in the 64 board KO.
So I passed in a flash.

C*****9 发帖数: 147 | 14 这是缺将牌Q大满贯局,一度为部分大陆高手所乐用:
通常对大满贯的安全首攻是将牌,因为对方是关键张全了才叫大满贯。但如果成了
规律就会有人利用,你在二手持AJTx vs. K98x或有AKJ的九张配合等情况叫大满贯
于50%。
我曾见到杨拿AKJxx vs. Txx叫大满贯,不飞而敲下首攻人Qx(那是一次节分制并处
于大后手的比赛)。这次对保加利亚比赛杨立新没有那么幸运。

我想杨叫7C时肯定在期待着缺将牌Q大满贯局,但是很不幸西持: S43 HQ865 DKQ93
CQT5是的确不会攻将的,但也敲不下来。

b***y 发帖数: 2804 | 32 Sorry, forgot to mention, they lead 4th best from length and strength, but
second best from no honor. So LHO will not have holdings like T8765, he
would have led D8 instead. |
|
w****b 发帖数: 623 | 33 I also wanted to ask this. The 4th lead makes the problem so much hard. If
it was 3/5th, a D return is usually right. And if pd led D8, there is no
layout that a D return would be right.
So if you get this wrong on table, your conversation should be: let's do 3/
5th lead from now on. You've chosen an unfortunate defensive method. |
|
b***y 发帖数: 2804 | 34 Yes, not equal, but I wouldn't say "no layout can be right with D8 lead".
Even though with D5 lead there is a higher chance that diamond return would
succeed, is there any layout that playing CK first (plan to return diamond
next) will cost, compared with immediate diamond return? |
|
a****s 发帖数: 524 | 35 suppose D8 (3rd/5th) was led.
Must play partner having an ace, otherwise you don't stand much chance, as
6S + 2H + 1D + 1A = 10 already.
Since playing him with SA is a bit far-fetched given the bidding, we will go
with CA.
I don't quite see how CK first would solve your problem. It has no
difference than playing a diamond first. since after CK stands, what else
can you do? not to mention the chance partner may disastrously overtake with
Ax.
CK was an illusion. You must decide NOW, either return ... 阅读全帖 |

Back to the hand, obviously there is no need to duck this trick. I win HJ
then play D8 to cut off communications. Partner has to have a diamond honor
to beat the contract. I think playing a club is fine as well, playing a
spade may put our side under unnecessary pressure when declarer has SK and
DA. |

b***y 发帖数: 2804 | 39 如果确知方块3-3的话,从手里出D6较好。假设左手D8/D9盖过,明手DQ,右手DK赢进后
续出方块,手里应该放D7(限制性选择原理)。左手持J8x,J9x,Jxx的时候会成功,
只有98x的情况是失败(J98的话没区别,总是做不成)。
如果加上方块4-2的可能,两种打法可能很接近。 |

实战中,明手放小,东家DQ,庄家DA吃住。打一张梅花,西家CA吃住,续攻方块,东家
DK赢进,再出第三轮方块到庄家手里,西家垫一张黑桃。此时方块已穿,庄家继续梅花
,东家CK吃到并再兑现两张方块。防守方共取得两墩梅花三墩方块,定约宕一。
东家实际持牌:52 / T982 / KQ952 / K6

|
b***y 发帖数: 2804 | 41 Actually you were right. I didn't realize dummy is missing D8. If LHO didn't
start with J8x, the contract is pretty hopeless. If he does have J8x, and
RHO only has 3 hearts and 2 clubs, the contract is now cold. |
|
b***y 发帖数: 2804 | 42 对方的叫牌不可信,一定是哪里有些搞错。不过你的打法基本上是可以的,也确实能兼
顾有些西家持四张红心的结构。有些细节可能要事先想清楚,比方西家2-3-4-4,第二
轮梅花东家赢进穿方块,如果比D8大的话,你要立刻DA吃住再出梅花,西家续出梅花则
明手不能将吃,要垫一张方块。 |
|
i****e 发帖数: 642 | 43 I had thought Q or 8 is a pure guess. It is nice to point out that the D8
is better to take care of KJxx in RHO.
What is in my mind is to play a heart, LHO plays HT, dummy ducks and RHO
discards a spade. Now we have 10 tricks. The only return for LHO is a heart.
Do you think this improves or hurts the chance?
clue |
|
i****e 发帖数: 642 | 44 Once we know LHO has 2 diamonds, we can play DA and small, avoiding the
guess I really hate. It will fail if both DKJ are at RHO.
LHO actually has DJx. So your careful play to D8 will succeed, and will
score easy 12 tricks by squeezing LHO in majors.
The declarer at the table unfortunately played D to Q, and later finesse DJ
for down 1.

|
b***y 发帖数: 2804 | 45 All these lines are pretty close. D to Q is also reasonable, any time LHO
has DK it guarantees the contract, it also makes in most cases where RHO has
both DK and DJ. Technically it is slightly inferior than playing to D8, but
almost negligible. In the end it is just about guessing which diamond card
does LHO hold. |
