a 5 loser hand with not really good controls in black suits and the value of this hand is solely on the strength of H suit

what if N make some preemptive bid after ur X? u will not be able to speak out ur H suit anymore
instead of bid H after X, u can also bid 1H 1st and show ur strength afterward (e.g. X, cuebid, jump etc.)

oh i see:smile_14:
you mean if you have some other cards to support the other suits, then it's better to bid X :smile_41:

the mainpoint is whether u can still convey the info in later stage
in this hand,if u choose X 1st, take an example, if N bid 4S, what will u do? 5H? dare to X after 4S?
nth u can do even u hold this good hand, so as ur partner, as ur X does not promise a strong hand at all

think of ur partner also
comparing X and 1H, which one can ur partner know more about ur hand?
bidding is not only a one ppl game

就咁睇, S: 12+, 4d+, no 5 major
而自己15 hcp, 單張鐵甲
只要partner 4+hcp, it is very likely that we can make a 3H contract
so i think EW has an advantage in getting the contract
therefore dlb forcing partner to bid

say, in an extreme case
N: 10 hcp, 5S and bid 1S
E: 0 hcp and pass
final contract 4S
although partner does not have any information on me
as S is dummy, I have strong defence cards

vs. a mild opp, this is not a problem
just consider ur "extreme" case, and opp not as wild as i described, N bid 3S instead of 4S, what can ur side do? possible 4H but u and ur p hv no clue at all!

回覆 #16 ninjablack 的帖子

my point is the possibility of 3H EW contract > 3S NS contract

assumption of 3S contract includes:
a) NS has 8+S cards, where I have 3 already and S has 5-
b) hcp of NS is above 20, since I have good defence

assume a natural distribution between N and E
(that they have similar point and card distribution)
NS is more likely to end with a D contract instead of S

so i will have time to show my H if they have no S major

moreover bidding 1H will be misleading to me
as I interpret 1H as 10-12hcp, 4+H only
while dlb imply 12+ hcp

倘若你叫 X/1H

你同伴應叫3S
你會怎叫:smile_41:

3S 應該係止叫
hcp NS> EW
partner 弱分, 長S
so pass

我和partner沒有這樣的規舉:smile_13:

同埋今個case, 假設佢知我有開叫牌力 (from my dlb)
partner 第一次pass, 然後3線開新花式, must be 5+ cards and is a stop bid (even I have no support) rather than an invitation for game contract

e, 你提醒左我wor
紅心鐵甲, 咁應該有機會4S bor:smile_40:

anyway, 我信partner, and partner信我
佢知我有擋,就夠上三線,所以可以唔理我邊門有擋:smile_30:

x 可以讓partner叫出他最長的花色
讓你慢慢思考
當然, 1H也是一個直接的叫法

各有好處

indeed, it is a compromise between you and your partner:smile_30:

ninjablack 2007-11-8 12:24 AM

what's the 3S here?
if not weak hand then will go 4S

alexskt 2007-11-8 06:09 PM

我這幾題都是一些牌型較怪的手牌
所以要考慮到怎叫是十分有難度的

3S 很有可能是我叫錯了
因為實際上我們的同伴是擁有6隻S   7大牌分

如果跟你個system, 唔係會2S openning嗎

如果是我 (開了牌後的吹水:smile_30: )
N dealer: P  - P -1D-X
             2D-2S- P -3H
             P  -3S - P -4S:smile_30:

我覺得partner應該應2S多於3S
同埋我都唔係好知點叫上4S (但應該會做到)

請指教

多謝大哥的提點
這的確是小弟的疏忽:smile_30:
看來我這個叫牌討論真是錯漏百出:smile_13:

雖然即使有7分大牌分, 6+up以上S仍然是可以不叫的

但看來這也是個不錯的選擇:smile_42:
