发帖数: 2804 | 1 If the condition of down 1 exists (i.e. RHO has 6025 shape), 5Hx may not be
that popular either. Lots of people might be pushed to 5S.
6H is a bad contract, you shouldn't expect to win the board. Just going for
25% is still better than 0. There will always be some pairs that are allowed
to play 4S there. (I am assuming this is another 低级双人赛). |

发帖数: 20570 | 2 pass in both hands.
For the first hand, you should pass then pull partner's possible double to
show a serious slam invitation. This hand offers a great chance in 6H if
partner holds AJxx Qxx xxx xxx, so you gotta try slams here.
For the second hand, pass is the only logical bid after partner's penalty
double. |

发帖数: 20570 | 3 The 4H is a minimum bid, so your partner can't hold a very good hand because
with extras, he can bid 4C. I would bid 1S with AJxx Qxx xxx xxx, but
partner can hold one more J or Q somewhere, which would be good enough to
bid 2S. This is just a minimum requirement to have a good play in 6H. Those
jacks or queens are not relevant in the slam decision.

发帖数: 2804 | 4 OK, so given that a 2S bid ought to show useful 8-10 points (and even some
good 1S hand would make slam playable), is there any hand that partner holds
which doesn't give a good play in 6H? |

这手牌就是我说的，forcing pass可能是理论上正确的叫品，但是如果同伴的2S假如真

发帖数: 2804 | 16 If partner has one more heart and one less club, it will be a much better
slam. But even with this given misfit hand, it is not hopeless. If spades

Partner can easily have xx KQxxx Ax xxxx, then 6H is really good. |

发帖数: 20570 | 17 Here, if you don't play fit showing jumps, 3C is very acceptable.
5H is not absurd either if his partner shows a D void. His partner may still
hold something like: AQxx xxxxx - AKxx, in which case, 6H doesn't have to
be very good.
This 1-5-7-0 hand is almost the minimum requirement to bid beyond 4H. Of
course, if you don't like it, you can change HK to HQ.
Another hand is 1-5-6-1 shape, in which case, you want to cash CA. Still, 5C
should show CA or void for sound players.

partner bids 3C, you can bid 3H. If partner bids 3H, you bid 3S as a cuebid
. If partner bids 3S to show 5-6 in majors and weak hand, you can cuebid 4C
to show some forward going interest, because your partner may still hold

发帖数: 2804 | 28 大概讲一下我的想法。
1）PASS是合理的，甚至可能是本手。不过我倾向于3H，因为四张红心质量很好。虽然
这个叫品有点冒险，但如果我方能成局，最有可能的是4H或3NT，这里都兼顾到了。缺
陷是方块偏短，降低了同伴红心配合的可能。如果我有四张小方块之类的，那么争叫3H
就更心安理得了。最差的叫品当属4C，既越过了3NT，又未必找到高花配合，梅花质量
也不够好。
2）基本的想法是加倍。如果同伴叫3H，我就再叫3S，这显示一手黑桃至少5张但实力不
够直接叫3S（为逼局叫品）的牌。这个牌直接叫3S有点过，冒叫了一个A左右。PASS也
是合理的；如果同伴不能在平衡位置叫牌，也许防守3D是最好的。不过如果PASS而同伴
加倍，那么这个牌就有点难叫，可能必须要4S了。
3）我的叫牌思想是，在前期的时候把牌叫足，即便可能有些冒叫。这样后面到了高阶
我就可以相对保守些了。比方这副牌前面2D已经显示至少5张方块10点以上的牌，跟我
实际持牌差距不大，这里PASS为妥。如果是好的对手，有局瞎叫的可能性不大。加倍可

发帖数: 2804 | 29 I can construct hands that 6C/6H is cold, or 5S makes. But it's everyone's
guess. In general I want opponents to take the last guess, especially at 5-
level. Go for best result possible, not best possible result. Pass.
Curiously, if RHO bids 5S immediately, I probably would take the push and
bid 6C. In the actual bidding, at least I had shown my club support after 4S
, so bidding again is really taking position. |

than 6D.
But the 5D bidding is far from scientific. If there is a way for the
responder to show fit and slam interest, and the open initiates RKC, it will
be easy to land to correct level, and can avoid a lot of guess work.

发帖数: 2804 | 33 对于5NT的答叫，比较标准的是回答最低级的K，而不是K的数目。因为第一轮控制已经
都齐了，剩下的问题是能否拿到13墩，有时候某张特定的K，价值远超过其它的K。
比方这副牌，对5NT问叫，应该回答6D，表示有DK（否定有CK，但不排除有HK）。如果
问叫方感兴趣的是HK，可以继续叫6H，意思为：如果你有HK的话就叫进7，否则就停在6

发帖数: 2168 | 35 totally agree:)
My plan is to play D to knock out dummy's entry.
If declarer has singleton S he can always get back to hand by ruffing S, so
I am assuming he has more than one S. In that case, he needs to use C to
pitch at least one S to get back to hand, so DA would be his precious entry
to later get back to C.
Therefore we should get rid of DA, now.

Declarer holds something like:

发帖数: 2804 | 37 It may also work when declarer has some weird shape such as 1-6-5-1.

is a big mistake. |

LHO holds Jxxx in trump, sometimes you can still pull off a trump coup. If
you are in 7NT but hearts don't break, often you simply cannot come to 13
tricks. Although we can never rule out a possibility of a ruff on opening
lead, I deem 7H to be a slightly safer contract, but both have good chances. |

发帖数: 2804 | 47 Actually the rough bidding didn't gain, it was still down 1. :-)
This is also one of the reasons why I don't like 4S as keycard. Potential
for disaster is high, plus it gives opponents a chance for lead-directing
double (or to find a sac), with minimal gain (only one bidding slot is
gained, and only matters when we cannot afford a 5S response). |
