Hopefully P will pass. We have majority of hcp and I expect 3h will fail and
we may not have any games.
2） 5S
Not sure if 4H is cuebid for S or D. If it is cuebid for D, then I would bid
4nt RKC for D. We probably have slam for either S or D.
3） Pass
No sure about any other bids, and I expect 3d to fail.
4） 2nt
I would pass at IMP.
5） 4S
There is no pre-emp against pre-emp. So I think p's hand is good but not
great (no X first). |

发帖数: 2804 | 3 I don't understand, why do you need an over-trick? In a normal field,
bidding and making this 27-hcp 6S (with seemingly wasted DKQ against a void)
will earn you a top. An over-trick will earn you the same top.
Trying for an over-trick is fine, but if it has even 1% of risk to
jeopardize the contract, then it is not worth it. |

发帖数: 2804 | 4 I think every bid was wrong (sorry for being frank).
1NT is off-shape, but that by itself doesn't create disaster yet. By bidding
1NT, you express the general value of the hand, but you also take the risk
of playing in 5-1 fit (which is the reason I wouldn't bid 1NT). Now you have
to accept that the bid didn't work out as well as you hoped, and honor the
transfer. When you bid 2NT, it should logically be interpreted as "super
accept", at which point partner has every right to jump to 4S with his... 阅读全帖 |

1nt range. N could count 7 quick winners - 1s 5d 1c. E has most left over
hcp and many finesses should be ok. N should bid 3h (to ask S to bid 3nt if
h can be stopped). |

allow him to win and win D later.

发帖数: 20570 | 7 Some thoughts on one hand
This hand was played in the bbo money bridge game. You play with a robot,
your LHO also plays with a robot. The score format is total points.
You hold Ax K9x xx AKQ8xx , both white,
The first question is what to open?
Of course 1NT is a possible choice. However, this hand is probably
too strong for 1NT because of the strong suit in clubs. You don't need
a lot from partner to make 3NT. So you should open 1C, even play with
a robot.
The bidding develops :
1C p 1D 1H ?

发帖数: 20570 | 8 The failure of gib is due to the wrong constraints. GIB thinks that I have
18-19 HCPs, so LHO can't hold both DKQ. Therefore, it's safe to cash all the
H tricks to avoid over tricks. The basic design of gib has many problems,
one of the key problems is that it assumes human opp always plays its system
. No any human players would always assume that opp has their bids and human
players know that opps may sometimes upgrade or downgrade their hands. |

In this hand, Zia and Rosenberg overbid to 4S after 1H(opp) 1S p 2H p 2S p

Of course this is a typical hand showing that the standard new suit
nonforcing style is very difficult to play even for top pairs like Zia and
Rosenberg. One clear improvement is to make 1S overcall sounder, usually in
the range of 1 HCP lower than a typical opening minimum and the responder should
play new suit one round forcing(still, it doesn't guarantee a rebid after

发帖数: 623 | 10 In my humble opinion, in bidding, there are two somewhat distinctive set of
tools: constructive, and destructive. The goals are very different. Of
course you can try to cover both with one set but that will have its own
tradeoff anyway.
Now if you recognize the very different goals, the key issue is to recognize
the situation. And I think that is the key here.
Top level experts can often utilize a very aggressive style as they may be
able to recognize who's bluffing better -- or maybe they can k... 阅读全帖 |

发帖数: 20570 | 11 Here, there are quite a few different schools. One is to play any suit bids
as cuebids to show honors, this is tuned for slam bidding purpose, which is
fine if 3C shows clear slam interest.
Another is to play every bid as natural. This is good for marginal slam
decisions based on shape and game decisions.
A third school is to play a hybrid method. So 3D/H are natural. new suits
are cuebids.
A 4th is to play the 4th suit to show doubts in 3NT, which is strongly tuned
to 3NT bidding, for example x... 阅读全帖 |

发帖数: 20570 | 13 1, It's a huge nonsense of modern bridge. If you have extra distributions
and a weak hand to bid, you should enter the bidding at low level, not pass
then suddenly bid something at 2 or even three level. By doing so (
especially when they have more HCPs than you), you offer them two chances to
beat you, they can double you for a huge penalty or they can fight back and
get more distributional information from you to make extra tricks than
before. Also, it's extremely easy to play against such ki... 阅读全帖 |

发帖数: 20570 | 14 I don't buy this concept at all.
If you hold a good and long D suit and around 14-15 HCP, you simply can't
make a takeout double first then bid your D suit. So you can only bid 2D
first and try to double the next round. For example:
- Axx AKJxxx Kxxx, the only possible sequence here is 2D then later double
2S as a take out.
Also, it's a nonsense to forbid the double with a void in this situation.
You opps are marked with a 8 card fit, so it's no longer dangerous to double
with a void, your partn... 阅读全帖 |

For example, partner may hold a very normal looking AQJxx x ATxx Qxx, it's
almost impossible to beat 2D double and very often, they make an overtrick
without any games on. This is a major disaster you should try to avoid IMO.
In some sense, the takeout double can never be based on too much shape and
too little defensive values. That's also why one sho... 阅读全帖 |

if that's a scenario comes more often, I can give up bridge.
One huger problem is that partner can usually have a defensive oriented hand

seems S QJx H QTxx D xx C AQJx, is a more plausible candidate. so partner
must not double with this hand?
It makes more sense that higher level double tends to show defensive value.

发帖数: 20570 | 18 This is simply the wrong bidding philosophy. Bridge is a partnership game.
What 4S achieves is just that I think I have an offensive oriented hand, if
they can make 4H, our 4S shouldn't be too expensive. It doesn't show your
shape, which can be very important for partner to get involved at high
levels. 4D shows a respectable hand, so partner can double their 5H with
suitable hands and 4S can be bid based on 7 spades, only 11 HCPs, like
KQxxxxx x KQJ xx. Here, no matter what they make, you know y... 阅读全帖 |

which can be obtained at the table.
let me just assume they lead 3/5, xx shows 10 HCP or more without S fit.
So RHO shows at least 6 spades. LHO didn't lead the obvious S. We can place
him to hold SAx or natural trump tricks like HKQx. D 3 is likely to be led
from three low D or 4 low D or QT3(2).
Now the basic idea is to ruff three spades. Anyway, you can win DA, CA, S to

4-5-3-1 and 9 HCPs. |

发帖数: 2804 | 21 Of course 2NT is not forcing, it just shows 19-21. 3D cannot be forcing
either, it is a weak bid, can be 5-5 in H-D, 0 HCP. That's why 4D is a very
odd bid. It must be based on lots of diamonds. |

发帖数: 2804 | 22 Slam value is impossible, you wouldn't have responded only 1H in first place
. For game hands, you can still cuebid first. I know this is not idea (
transfer is a better treatment), but when partner makes a limited bid on
balanced hands, responder with weak hands often wants to place/improve the
contract. Just like after 1NT opening, responder would sign off with 0 HCP.
Now we have transfer, but in the old days, 1NT-2H is just a sign off. |

发帖数: 2804 | 23 In MP, if partner opens 2NT, are you not transfer (then pass) with 5-6
hearts and 0 HCP? When you have shapely hand (but very weak), often a suit
contract is much better than NT. It is not just about safety, you are trying
to improve the contract. Your hand can be worthless in NT but worth
something in suits. |

发帖数: 2804 | 24 Anything beyond 3NT is bad. 3H can show honor doubleton, since the 2NT tends
to deny 3 hearts (otherwise double 2C). 3S would be fine, showing some
doubt about the strain. Even 3NT is acceptable, since that is the most
likely game (and pays extra dividend in MP). I think 3NT is a little
committal though, but 4D is neither here nor there with this hand. In MP you
just have to try hard to keep 3NT as a possibility, you need a strong
reason to go beyond it, this hand just doesn't warrant it.

Suppose you win CA, play DJ which is likely to force out DK. then you ruff C

HA, play D to take another S finesse, your chance is indeed pretty good,

发帖数: 20570 | 26 There are some fundamental problems in gib bidding. The largest problem is
not its system, its simulation, but it's hand evaluation. Gib's hand
evaluation is based on total points. In trumps or no trumps, it always
assumes that with 25 total points, it would force to game, with 31 total
points, it would force to slams (based on double dummy analysis, 31 total
points can often be enough, however, we all know 33 HCP is usually good).
That's why you see gib sometimes becomes incredibly crazy when h... 阅读全帖 |

see very strange thing, for example after you open 1NT, GIB would transfer
to 2H, but then you find it has a balanced hand with only 4 hearts.
In general, there should be initial rules to follow, for example if you have
13 HPC with 5 spades, you should open 1S. There is no need to construct
sample hands to decide what to open, it is all part of the bidding system
and you have to trust that the system is designed well. P... 阅读全帖 |

发帖数: 20570 | 28 Let me set it straight. Most constraints set by gib are based on total
points. A certain bid usually means a certain amount of total points and
some shape and suit quality information. Then the rules are just based on
total points. Here comes the key problem, both no trumps and trumps are
based on the same total points system. The total points are based on HCP and
distributions. It is simply absurd to count a void as a 3 total point asset
in no trumps. However, gib does that in every hand. So as... 阅读全帖 |

发帖数: 20570 | 30 This hand is also not a clearcut to bid 3NT. 5D can be a quite nice bid,
because partner shows slam interest and outside of H, you still have 9 HCPs,
which is usually enough to have a reasonable play in 3NT. Your H is not a
sure double stopper and your D is relatively weak. 3NT is clear only if you

You couldn't even provide any bridge argument on why you have to bid 4H with

hand without a lot of distributions. Yet, you catch a really good hand to
fit your DQxx, HKT9x and CJ9xx to have a less than 50% game, which can be

For example:
KQJx x xx KQxxxx, this looks like a good 4S since both contracts can easily
be made or 4S sac can be very cheap.
I wouldn't bid 4S with your listed hands, because my general philosophy is
that I don't want to be pushed by opps to a high level with balanced hands. |

HCP featureless hand from your partner. Bidding 4H here is so wrong in a

hand is slightly weaker than an invitational hand if you don't find a fit in
major. Of course I understand the upside of the redouble. This kind of

whether to redouble or to bid my hand is that if I hold no 5 card suit, I
