不明白这用的是什么叫牌法?按照Blackwood Convention,开叫1NT应叫2C表示两个高套
都可以打.

No major also can use stayman, in some convention.
I had used 2C stayman, then 3C ask minor suits, anyone ever used that?

c****u 发帖数: 3277 | 11 如果假设西有HA, E有DQ,那就让明手DA过去,兑现两轮club,
手里垫两个红心
South has : S5
HKT
DKJ
西受挤,只能留成 1s HA, Hx, Dx Dx, 然后飞过dia, 兑现Dk,
sp投入西即可.
如果E有HA, 西有DQ, 定约几乎无法完成。

If west has HA, east has DQ, your way works well. However,
if east has both HA and DQ, or west has both the cards, what
will happen?
There is better way :-) will post in next week, if no one try
to answer it.

b****y 发帖数: 105 | 14 wann's answer is right.
The declarer, Perron from France, played the fourth spade and made
the contract.
Why this play is the best way? In the following I am trying to give
an explanation. (please correct me if any error)
after this round, the remaining cards of N/S are
N: D A832
C QT8
S: H KT97
D KJ4
Now west has only H & D to play.
1. west play HA, follows a small H(Q/J)
drop 2 small D from dummy. East must keep 3 Clubs, at most 2 Dimonds.
Now lead a small |
b****y 发帖数: 105 | 15 The real distribution of the hands is:
West: S KJT6
H AQJ864
D 95
C
East: S 987
H 3
D QT76
C A9643
In the 6th round when Perron played the fourth spade, east was forced
to drop his H3. West felt that cashing HA was not good, so he played
back a small D. Cashed DJ,DK,and DA, Perron played the fourth D and
east was again been throw-in and dummy's CQT8 won the last three rounds. |

After two round of clubs.
In this case, if west hold D Q X X
Contract will set one 'cause squeeze doesn't work.
~~~~~~
Contract set one.
Already: 2 Spades, 1 Clubs
Potential: (1 Dia and 1) Hearts or (1 clubs and 1 Hearts)

西还HQ,而东在之前垫过一个dia, 大概依然会飞dia,这就跟我的打法没什么区别了。

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
西如果不回HQ, 不增加了做成的机会? Spade 肯定是要丢的。
主动进攻在这并不太好(偶是这样认为的 :-), 不如交给对
手, 给对手犯错的机会比自己犯错好多了. 同时还保留飞的
机会.

如西还HQ你不需要飞DQ.因为如果东有DQ,TA会被投入.
