假如2H后,西家的机器人加倍,我的首功肯定是打宕定约的H。于是,选择了其他的花色。机器人不打首攻指示性加倍的话,我在红花色中如何选择出H的首功来。

哦?您敢说首攻J打宕4定约?
Ok,就让我们演练一下吧。
你首攻J,明手垫6!
此刻您拿不拿?
1-A拿掉这一顿,再交你两墩,我真的看不到您的第四枚赢墩长在哪里?
2-不拿忍让一墩,那就没你的赢墩的份啦,交两墩,交一墩,您的第四枚赢墩长在哪里?

别忘了,你和搭档的全部边花都是至少分布三张,--额外将吃无缘没份儿!只有3枚赢墩。

嗯,我看错了,4是铁的。
A拿后,打给A,兑现Q,X到手上的A,用K和KQ可以垫光明手的

只是庄家要注意次序,K一定要垫走一张,不然KQ大牌带不完明手的

谢谢老师指点。

4s那里铁了?攻h,hA后换c就简单宕了。当然,打出这样的防守需要想象力,通常是防不出来,但至少不是铁牌。

The first lead does not matter here. In the actual play line actually quite accurate to let W get in at trick 4 and return at trick 5. All E need to deduce is that N hand has no more developed tricks to discard S hand loser (from the play that is discarded as losers and is well guarded). Therefore all E need to do is to draw all declarer's remaining trump and left dummy with 2 inevitable losers. Just as simple as that.
