这副牌例取自中高级牌手论坛。
问题是:出题人认为可以开叫2,试问:
1-我违背了2开叫原则了吗?
2-换作你,如何开叫你?

2C原则:当你决定用2C时,先找找有没有其更适合的叫品。
只有当绝对需要才这样做。
让应叫人叫牌更简单。
我认为:H套足够坚固。2C后,再叫4H可以明确表示牌情:九个赢墩,与成局确实是一步之遥。
请具体看一副牌例,体会一下:

IMO,我是开叫1,因为手有五失墩。

不过从BBO论坛上看,大家意见分歧大,一部分是我的观点,一部分人支持开叫2.



注:什么是IMO?
网络用语,是In my opinion的缩写,意思是:“在我看来”。
事实上这个词通常是论坛掐架的开始,它的变体有Imho(In my humble opinion:管见所及),基本意思是:"区区在下不才,对这个问题是如此看的,阁下若有高见,尽请说来"的意思。

开叫1,开叫2除了赢墩外还需要大牌点和防御墩。

这牌h独立套8.5~9 赢墩,而不是8-8.5赢墩,开1h实在是低开,就开2c,我想同伴也会乐于接受。
开2c进程2c-2d-4h很清晰表明牌情,让同伴来选择是否继续前进;
开1h,外面的低花分布和28点,多可以再叫,虽然不至于丢局,但是同伴不会想到牌有那么强。比如1h-1s-4h的描述,会不会误解?

2是至多三失墩的牌情。也有一说是四失墩。

这个H套并非坚固套,在缺少一个顶张大牌的前提下怎么没人考虑4C开叫呢

什么样的套称得上坚固?
我把AKXXXXXX八张当做坚因套的。就像经典牌例中把AKQXXX当做坚固套一样
如果要100%的坚固,应该是AKQJTXXX AKQJT98 不是吗?
我们所谓的坚因套,一般情况下(计算的是多大概率)是坚固的即可.

风扬说:书上讲,2C开叫人仅需同伴微弱支持即可成局。那就是说九个以上赢张的说法是靠谱的。

这么怕丢局么?开叫2C是不会丢局,如果同伴给你叫满贯呢?开叫1H有什么可担心的?下一轮4H。或者有约定叫显示好的高花坚固套开叫也可以。

这牌是开叫1,4,2都有点相似的牌,又觉得都不怎么完美的牌,最符合叫牌法的开叫还是1, 但我会选择开叫2C
后再叫4,不过我也不想太高兴,定约权落在opp手中也很正常

像这类问题,没有标准答案,只有依据个人理解而定。那边论坛的意见也是这样的,有赞同也有不同意的。
不过,需要注意的:
1-这也几乎接近美国桥协所规定的开叫2的最低点力要求。
2-开叫强2绝对不允许心理叫,这是规则。

有4C约定就开叫4C,不然开叫1H,基本上不去开叫标准2C,除非有约定2C-4H(坚固套8-8.5赢墩)那可以使用2C。

开叫4是个不错的选择。
风扬举的例子可以开叫4,相信也会发展到满贯的。

我赞成开叫4C,
开叫4C表示8或8.5个赢敦,该套可以缺K或Q
开叫2C后跳叫4级高花表示8或8.5赢墩的非常坚固套

2c是不合适的,有赢墩也不得少于17P;
4C纳米亚茨是合适的;
区区12p,pd 弱应叫,很难想象opps 不参与叫牌。一旦参与,应叫人也许会采取错误的行动。

有赢墩也不得少于17P?从未见有此说,很是费解,不知所云。

贴主的牌例也许没有违背ACBL的底限;the ridiculous ♠ --- ♥ AKQJ76542 ♦ 85 ♣ 74 is an acceptable 2C opening bid under ACBL regulations.
但通常是这样的:
General Requirements for an Opening Bid of 2C:
A. A strong balanced hand of 22 or more high card points - or
B. A strong unbalanced hand with a 6 card suit or longer – and – at least 9 playing tricks
– and - at least 4 Quick Tricks in THREE different suits - or
C. A hand so strong (24/25+) that it risks being passed out with an opening 1 bid.
