发帖数: 3277 | 1 Offense-to-defense-ratio is widely discussed. However, upto now, there is
no such formula to give a number of ODR. I am wondering if it's possible
to study a lot of hands, make extensive analysis,
and generate a formula for ODR. Actually ODR should
be dynamic and changes when bidding develops I think.
However, I firmly believe that there might be something in
common for the hand-evaluation. | w****b

if you wish to open 2C or 1D.

发帖数: 3277 | 5 实际赢墩和预计赢墩的差值, 实际防守赢墩和预计防守赢墩的差值是重要的衡量
odr的参数. 也许可以从最简单的问题入手, 比如
AKxxxx 这样的套, 在同伴简单加叫后平均防御赢墩是多少, 平均赢墩数是多少.
如果没有加叫后, 平均赢墩数, 平均防御赢墩.
已知敌人8张配合, 如果左手长, Qx 的预计是多少, 左手短, Qx的预计防御
赢墩是多少, 类似的花色组合非常多, 如果获得这些统计平均值, 也许会对
odr的计算有很大帮助. 说到底, 很多时候叫与不叫还是看这两个差值的
关系我感觉.

发帖数: 3277 | 7 you are also welcome providing some comments and suggestions.
Actually, I think we need a lot of discussions before we reach the
programming stage.

发帖数: 623 | 8 Sigh. I posted a long message this morning and then the server went down and I
lost it all.
Anyway to start with, I was proposing the ratio of winners when defense over
the losers at offense as a starting point. The initial consideration can be
restricts to only the two main suits (oppo's and our's).
Assume both 9 card fit without a loser, then the expected winner on defense is
about 1.4, and the expected loser at offense is definite. So in a 3-1, 2-2,
1-3 case, the initial ratio will be 1.4/1,
