2NT as first response. Probably he/she realize that later and that produced
the 2H.

c****u 发帖数: 3277 | 5 Well, I don't think there is any relationship between "modern" and
"highly natural". The inventor of fourth suit forcing once said that
his invention is not a convention, but a logical deduction.
I think modern sometimes means aggressive though.
In culbertson's time, they play strong two and strong three which is highly
natural. People nowadays play weak two and weak three which are highly
natural as well I believe.
I almost forgot his convention against interference over 1NT.

If you decide to bid 2H. I have to admit its legitimacy. But maybe you
are not quite aware of what you are doing.
Given the 1NT response, most likely, you are going to play in notrump and
won't have any crazy dream of making a slam. Thus the only problem left
is whether you bid a game or not. Who are going to make the decision for you?
obviously, you should consult your partner. The most straightforward way to
do it is giving a 2NT invitation.

g**********y 发帖数: 14569 | 13 From your pd's perspective, I think 2H is better, because --
In standard system, 1D-2nt shows 19-21 points, very likely 2nt would push your
pd to 3nt.
But 2H shows 17+, now it's your pd's turn. He knows you are 17+, if he respond
2nt, it's a sign that he probably doesn't has extra value. If he bid 3c, I
would take that as invitation for 3nt and go for it. If he bid 3D, I would
most likely pass.
pd's 1nt shows 6-10 points and no 4 cards in major. Given that, I think game
chance is slimmer than pa |

c****u 发帖数: 3277 | 16 With Andrew Gumperz, we play 4 card major opening and no invert minor raise,
so 1D p 2D: simple raise;
1D 3C: GF raise
1D 3D: invitational.
1D 1NT: still can have a bad 4 card major...but it is NT oriented....
over 1D 2C:
2D: showing 5 diamonds, any hand
2H/S: usually denies 5 diamonds, can be 4-4-4-1 or 4-4-3-2 balanced.
2NT: natural, 12-13 HCP.
3C: extra value or good clubs, with good clubs, we always push to game.
This structure works fine I think.

w****b 发帖数: 623 | 17 The advantage of inverted minor is by reserving more spaces, it keeps your
option open and often offer a better chance to cater to 3N, 5 of the minor, or
the minor slam.
The disadvantage of inverted minor is the invitational minor fit hand, or
invitational hand with other minor, can often be a challenge -- that is, if
you play inverted minor for game forcing -- jumping to the other minor can
introduce other problems, so in many cases, you have to either bid you 3 card
major or bid 1NT, which oft |

w****b 发帖数: 623 | 22 You'll have to rebid your C's. 3D in this case is usually not natural. It
should either show a good raise in S and cue, or a lack of direction bid --
even if it's natural, you wouldn't expect pd to raise you with 3 piece AQx.
I would start with a modest 1NT.
(1) If pd responds with 2C/D, we've found at least an 8-card fit and I show my
hand by 2S, then I can pass pd's 3N with peace of mind. Or if pd's suit is D,
I'll pass his signoff (even if he has AQx of D, you may need C ruffs to set it

Forget about the field protection at BBO... as most people's defense are
relatively primitive which encourages overbidding.
As far as 21-23 3NT sometimes there's a good reason. Sometimes you don't see a
way to get there.
I remember a hand from a regional open pairs. I held AQx Q8 T8x AKJTx, both

c****u 发帖数: 3277 | 25 if you play 1NT as forcing or semiforcing, it's usually not a good
idea to introduce your 4 card spade suit with about 16-bad 18 HCP,
because partner usually denies spade suit. so you should normally rebid
2C or 2D here. Thus, we have a free bid: 2S. This 2S can be treated as
GF and starts a relay sequence.
1H-1N-2S:
2NT:relay.
3C/D: natural.
3H: 6 card hearts, about 19 HCP, ask partner to place the final contract.
3S: 5-6 in majors.
2NT: 4-5 in majors.
4C/D/H: self splinter in C/D/S, |

c****u 发帖数: 3277 | 26 The point is that everybody would find 7 NT no mater what he opened.
Also, when the solid suit is major, you usually have more gadgets, because
you may bid 4D over partner's 1NT as splinter to show this kind
of hands. Still, I'd bid 4D with AKQJxxx HQxx Dx CAx. you need partner
to provide three cover cards, something like this: Sx HAKxx Dxxx CKxxxx.
If you open 1S, you still may get passed out if partner holds S- Hxxxxx DJxxxx

No, I am not only talking about bermuda bowl. bridge is somehow a game of

One thing I am sure is that you can't really understand strong pass system,
nightmare, etc in half a week.
Well, that's aggressiveness, not really destructive. I've read a lot of
their hands actually. Actually Meckwell's system is quite straight forward
comparing with other destructive methods: like 8-10 super light 1NT,

no, we have no way to show 6 good clubs and 3 diamonds if we reverse.
if partner raises 2D to 3D, we would have a big headache to get to 6C which
could offen be a better spot. I don't like my 2NT, but it was just a tough
hand for our system. 1NT opening is kind of conservative, 1C then 3C
is possible, but we still may have a problem if partner bids 3S as forcing.
Once I bid 2NT, we do have some easy gadgets. Thus, I believe 2NT was the

It's a misunderstanding that rebidding minor just shows 5 of them. True it

c********n 发帖数: 17 | 44 Bidding is not playing, it is convention between partners:
3NT here means clearly 5332 10 or so HCPs.
Pass 3NT means 2-3 S, stoppers in other 3 suits.
4S means 4 S support (another form of "8 never, 9 ever" :))
The rationale behind this is. unless 1NT hand can ruff something, 4NT can be
made if 4S can be made in most of cases, but 10th trick might make hugh
difference for a 3NT hand with 4S bid.

c****u 发帖数: 3277 | 45 After transfer, it's often very important to know the exact shape
of opener's to decide how high and what suit to play. So it makes

With invitational hands, one can bid 2C then 2S later to show it.
