點解係pass:smile_41:

pass

小弟認為如果對手可以開叫, 咁假設佢有13分, 佢partner可以答叫, 小極都有6分呱... 咁佢地最少都19分.
咁我地都係廿一、二分, 上game好似好危險...

但係你有時都要考慮一下distribution的問題
當你一手牌有1副雙張,一副單張
對手很有可能係差唔多情況

咁如果計埋distribution ge話
對手咪可以開叫!!!!!
還記得你partner double嗎:smile_41:
他之後還叫diamond
即可能他少heart + 多diamond
何不上game:smile_41:

if E is a reliable p (wont lie on table), i would bid 6D

ninjablack 2007-10-27 11:15 PM

the reason is that E made a 4D free bid after X, which implies a strong hand with strong D suit
though S bidded 2H after E's X, but with the assumption above and ur hand hold, i think S's hand is rather weak hand (0-6) with H support(e.g. xxxx /Qxx in H) instead of normal 6+ 3cd+ H support
the reason that S bidding in this way is due to the uneven hand shape that deserve a competitive bidding here

with the fierce competitive biddings by opps, it's likely that ur side wont waste many HCP in H
with opp's HCP lying in N's hand mostly, that would favor finesse by us, and thus ur C suit can provide source of tricks for discarding losers in p's hand

Agree 4D is showing strong diamond suit. Therefore, it doesn't imply a classical shape like 4-1-4-4.

Therefore, the chance of double fit is not that high and I would like to keep the bidding low by simply bidding 5D and end the auction.

The chance of making is still high, and by law of total tricks, it would be a good sacrifice if 5D doesn't make, esp you are holding a stiff in heart.

(By the way, I would had bidded 4C instead in the first bid ^^)

[size=4]請考慮一點:[/size]
[size=4]對手叫了heart suit, 之後又應叫3 heart[/size]
[size=4]對手的heart一定很強[/size]
[size=4]你的partner double, [/size]
[size=4][size=4]他的分一定在13分up[/size]
更表示他的heart短
他很可能有club Ace King 或沒有clubs 但spade強[/size]

North 有13分
South 又double後bid, 可能有幾分support partner
partner同我最多得27HCP甚至更少
5D有D危
我都係pass.................

This hand is not for NT, skipping 3NT is therefore not a loss.

Bidding 4C can show a good hand which has a strong interest in 5C and allows room for corrections if partner is holding spade suit.

呢副牌, 可以先叫5D或者滾6D
p剪完出D起碼16分, D應該有KQ, 淨低11分, 樂觀D咪兩條A, 加埋potential飛中CK就6硬; 想穩陣D就5D話有D支持囉:smile_38:

I am not playing bridge safe. I play bridge for highest expected gain.

If you want to be safe, even though you hold 28 HCP together, you should still stop at 1NT. :loveliness:
