overcalls

overcalls

1. The R2SO were later replaced by the Blue two-suiter overcalls which is more descriptive and effective.

R2SO后来被更详尽和有效的蓝梅双套盖叫法取代了.

2. Generally, the BWS requirements for initial constructive defensive actions (takeout doubles and overcalls) are moderate, but two-level overcalls are sound. The vulnerability somewhat affects the minimum strength required.

一般而言,BWS对于加入竞叫(技术性加倍或插叫)的基本要求是中度牌力,但二阶插叫就要更好一点。所保证的最低限力量多少也会视局况情况而定。

3. When responder raises a preempt below game, whether competitively or not, and an opponent overcalls, opener may not bid and there is no special agreement over whether he may double.

当应叫者对阻击开叫加叫但未成局时,不管是否为竞叫场合,若敌方再叫牌,开叫者可能不叫牌,但是否可能加倍则没有约定。

4. The requirements for initial preemptive defensive actions (jump overcalls; the weak version of two-suited actions) are possibly light.

阻击性插叫(跳争叫;两门花色的弱阻击叫)的基本要求可能较轻。
