我本来是想向大家推荐一本好书，ROBSON/SEGAL的“PARTNERSHIP BIDDING AT BRIDGE”，发现大家没什么兴趣，本来也就算了，刚刚在另一个帖子http://www.szbrg.com/bbs/showtopic.asp?id=902&forumid=4&page=3里有关于阻击叫的有趣讨论，我感觉大家如果看看这本书还是有帮助的。当然书是英文的，200多页，如果你阅读以下的文字有困难那就不必费事了：

a) One-major - simple overcall

West North East South
- 1H 2C ?

-2H: natural; usually three-card support;
-2NT: high-card raise with four (plus) trumps and a reasonably high ODR -’limit or better’ values;
-3C: high-card raise with three trumps (or four trumps and a low ODR) - ‘limit or better’ playing ;
-3D: fit-jump to the three level;
-3H: semi-preemptive raise, with four-card (plus) support;
-3S, 4D: fit-jumps to the four-level;
-4C: splinter-jump;
-4H: preemptive raise to the four level;
-4S, 5D: TO PLAY; not fit-jumps.
