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.
