发帖数: 623 | 1 My humble opinion...
4 card overcall is routine and often necessary in matchpoints, as it tends to
be very effective in partial score battles, plus, as cozofu pointed out, this
game of bridge is more of a game of S than any other suits, particularly so in
matchpoint. In imps, your strategy is usually to play sound and you want to
avoid any disasters, and you really don't care about the differences between
+130 and +140.
Opening is something different because your rebidding problem (to show secon |

发帖数: 3277 | 2 you can't always expect for perfect hands. Also, do you think you'll
find 5C without the preempt? There are tons of perfect hands which
can produce a game or slam, but bridge is not a game seeking for
perfect fit. If you try to always get the perfect hand, you'll lose
in a long run for sure.
Also, defending 4H would yield you a positive score, that shouldn't be
a bad score in MP or IMP pairs. If you double and partner bids
4S, would you bid again? That would be a totally guessing game,

发帖数: 295 | 15 Admittedly, your play did have some point.
After ruffing the 1st trick, you can tell that your RHO doubled with
spade AK and trump Ace. Yes, he might have trump AJxx, but there's
no particular reason to commit yourself to that layout. The best way
is just following the percentage play, leading trump twice from table.
Generally, if you are worried too much over nothing, you lose more.
and I believe most of the time, if a bad distribution exists, you can
smell it.

发帖数: 65 | 19 In a MP field, just finesse CQ and try to ruff the 3rd club, because there is
a chance of making 11 tricks, and if LHO holds A32 in trump AND the CK, yes he
finds a great lead and you have to pray it is a low average instead of a
bottom, ie, someone share the same result as you.
In an IMP field, finesse the C9 first. Say it loses to J/10, you still have a
dummy entry in trump to finesse the CQ for the 2nd time, because you only need
10 tricks.
Looks like a "textbook example".

I bid 4H simply for gambling since we are 10 IMPs behind and I think this is a
good chance for fight back.

发帖数: 3277 | 27 Why do you trap with a gameforcing hand? If you can make a game facing a
minimum opener, you should never pass 2D. Now you probably get the point,
2H should never be a dead minimum because partner has denied a gameforcing
hand. Facing some extra value, this hand isn't bad at all, game can be
made facing a lot of minimum reopenings, so just bid it. It's never a matter
of game status and you shouldn't overbid even if you are 10 imps behind
unless you have a very good reason to do so, such as "opps |

发帖数: 3277 | 33 五月十九日BBO自战评述
今天我和杨庆在BBO和Hansa Narasimhan,
Irina Levitina打了一次多桌IMP的练习赛。
她们为即将到来的美国女队选拔赛备战。
Hansa是一个在北加州的桥牌爱好者和赞助者，
Irina是北美顶尖的职业牌手之一，她还曾经获得过
国际象棋的世界冠军的挑战权。
她们打一个比较自然的五张高花开叫体系，标准的
防守信号。
我和杨庆打一个改动相当多的2/1体系，反式信号。
第一副牌双无，杨庆在北家pass, 东家 Irina 开叫1D,
我拿了SJT42 HAJT53 DKT7 C3,
你是决定pass还是叫牌那?
由于是无局，4-5-3-1的牌型，这手只有九个大牌点，
但是点力都在套上，十也很丰富，所以多数牌手拿这手
牌都会争叫1H的。我没有做多少考虑，争叫了1H.
Hansa叫2C, 杨庆叫了2D, 东Pass.很显然他有一手好牌，
即便如此，我们也很难打成局，因此我叫2H是必然的。
Hansa稍微想了一下叫3C,
北和东pass, 你现在叫什么?
很显然Hansa和Irina都是拿了相当低限的牌，这手牌
很可能是20对20的大牌点。杨庆大 |

发帖数: 623 | 34 这个深有同感。
这里我想说的是，有时候实战中未必能够找到最理想的路线，
但即便如此，很多时候也未必会受到惩罚。但是希望进步的牌手
往往是通过事后的分析来找出这些潜在的问题。如果你在日后
实战中十次这类情况下分析对了7－8次，这7－8次就是你潜在的
获得IMP的机会。另外，这类花色选择信号的交流也是非常必要的，
很多时候这些信号可以解决同伴的猜测问题 |

My analysis is as follows. It is not perfect, but I am quite sure the

This is MP. And you are defending 5Sx. Some table will play 4Sx. You
are not competing with them. So let's consider 5H. If it goes down,
then no matter what you do you will get a good score. SO we have to
assume that 5H makes. IN this case, we have to defeat those bid and
make 5H. As they will score 650. We have to score more th |
