注:E3H为实叫。
请问:1、E叫4D是满贵试探还是对3NT的更改?
2、如果是满贵试探,实力是否够?
3、3NT后E是否应该pass?

看来东西不使用转移叫。3H作为实叫及逼叫,比较老套。

1&2. 东11点,加上同伴13-15,应该不足以试贯。4D应该是对黑花色被攻穿的担心,想作4H或5D。这也显示了3H叫牌的弱点。
3. 在这样的叫牌序列下,很难回答,纯粹靠猜。就实际持牌,是3NT更好。如果CKQ换成CA,是5D更好(4H也行)。

如果东西使用转移叫,通过如下的叫牌序列,东pass 3NT就比较放心了:
1NT - 2D
2H - 3D (第二套)
3NT - pass

如果东西想用3H/3S作为强牌逼叫(实叫),最好是6张以上,已经确定H/S为将牌。以后的其它叫牌,属于扣叫。
