2D = 18-20 balanced
3D = transfer (unfortunately your methods don't allow you to transfer at the four-level)



本题面选自BBO专家牌手论坛。
提醒:
2=18-20hcp,均型。
3=转移(不运气的是,你们的约定不允许你直接在4阶上作转移)
问题:你如何首攻?

如果不是解答题目,而是实战中,我几乎也是攻C5,也有可能攻HQ————程序化的不作为。

现在是考试。同伴拿着18-20点的均型,自己有3点,敌方18点左右叫上4S,依靠的是牌型和配合;另一方面同伴选择加倍,多半是H短和弱。攻将以削弱明手将吃能力,后期可以不断的投入庄家。

我觉得应该攻,期望取得边花的赢墩。万一同伴被投入,至少还有可出脱手。

This is the full hand:

I led a club, but that let it through: club lead ruffed, A, heart ruff, club ruff, heart ruffed and overruffed, K to the ace, spade back to the queen, endplaying East.

I think the club lead is a mistake. They've bid to 4 under their own steam, in at best a 9-card fit, when we might have beeing stopping in 3. They must have some shape to justify that. In particular LHO, a passed hand, competed to 3, so he's likely to have a shortage.


大意如下:
如图是全副牌。

我首攻,但是意想不到的是:被将吃,庄家拔A后,将吃H,接着将吃,再将吃和东家超将吃,然后东家K,庄家A,再反将牌J,东家Q拿住。进入残局投入东家。

我认为首攻是错误的,他们已经叫到了4,已经表明最多9张配。当我们可能停在3H时,opp必须要有一些牌型作掩护,尤其是左手家,pass过的一手牌,敢于竟叫到3阶,所以他很可能有牌型,有短张!

讨论时,有太多的人都感觉首攻有多么合理,想想吧,你南家都手握2张S,同伴均型牌有几张S呢!那么明手如果是牌型牌又能几张?他竟叫的目的无非是看重的是将吃的价值!他还会有赢墩牌力?还会有别的构思?
对付牌型牌,虎口拔出明手的牙为紧要,因为同伴18-20p控制张很多,没什么可担心的了。
