How can south make sure that 3H not cue bid, but 3-card H?
if south has AQTxx Ax Kxxx QJ, what to bid after 2S,
2N showing semi bal or 3H cue showing slam interest?
if south holds AQTxx Ax Kxxxx x
is it still the same bidding?

发帖数: 2804 | 4 3H should not be a cuebid. When trump is agreed at 2-level, it is better to
use 3-level bids as shape-showing. At this point you have room, slam
interest can be shown later, first priority is to get to the best game. So
3H bid should show 5341 shape. With 5242 you can bid 2NT.
However, the given bidding sequence may have been affected by looking at
both hands. Usually the bidding would start with 1S 2C 2D 3S, it is
important to immediately show slam interest with good trump support (by
jumping to 3S). 2S works nicely with this hand, getting to a superior 4-3
fit rather than 5-3 fit, but bidding should not geared toward that.

发帖数: 20570 | 5 2NT shows balanced hands. 3H has to show 3+ hearts here.
3H is not a cue, but shape showing.
For the second sequence, you have to guess. 5-3-4-1 is way more likely than
5-2-5-1 and 4-2 7H is still not a very bad contract, especially after opps
keep silent.

发帖数: 2804 | 6 Sure, but that is exactly you want, right? In this case the best contract is
7H with 4-2 fit! :-))

发帖数: 20570 | 7 3S to show slam interest is not in my book of bidding. In a gf sequence with
gadgets like non-serious 3NT, there is no point to jump to 3S to show slam
interest. Slam bidding is a fine art of showing the shape and strength after
2/1 sequences.

发帖数: 2804 | 9 It depends on your entire system structure. When trump is agreed at 2-level,
many experts don't play serious/non-serious 3NT, since you have room and
3NT can easily be the best contract. Therefore they need to use 3S to show
slam interest with good trumps.
Even if you don't use 3S for that, it is better to assign some specific
meaning to it, so you can offload other bids.

北开叫：
1S - 1NT
2D - 2H
2NT - 3C
3S - 4C
4NT - 7H
1S = 11-15，5+S
1NT = GF
2D = 11-13, with 4+minor
2H = relay
2NT = 4D
3C = relay
3S = 5-3-4-1 shape
4C = RKC with S as trump
4NT = 2 key cards with SQ
7H = This is all I need. Even partner has no other side K, we can still
make 7 since dummy can ruff two clubs.
南开叫：
1C - 1S
1NT - 3D
3H - 4C
4H - 5D
7H
1C = 16+
1S = 5+S, 8+HP
1NT = relay
3D = 5S + 4D, 12+HCP
3H = relay
4C = 5-3-4-1 shape
4H = RKC with S as trump
5D = 2 key cards with SQ

发帖数: 20570 | 14 If you don't play any strength showing bids after 2/1, you system is
incomplete.
If you jump all the way to show slam interest after 2/1, you system is
inefficient.
Of course I have 3S reserved for some other meanings.

发帖数: 1284 | 20 Groetheim不是已经不用CRASH了么？他们体系的新发展是问完牌型后如果叫品仍然低于
4D，则用4D做结束信号，强制转移到4H后再表示对特定花色的满贯兴趣。3NT总是止叫
。除了4D和3NT以外最便宜的花色都是以特定花色为将牌的RKC。比如北开叫的情况，3D
（5-3-4-1）后南最便宜的叫品是4C，这是以最长套（这里是S）为将牌的RKC。如果南
叫4H，则是以次长套（这里是D）为将牌的RKC，依次类推。如果有花色等长的情况，优
先级人工设定为H>S>C>D。
