Re: Cube Action?

結論から言うと、No double/Takeで、実戦ではDouble/Passでした。

コード:

Cube analysis
2-ply cubeless equity  +0.7138 (Money:  +0.7309)
  0.6897 0.4067 0.0768 - 0.3103 0.1288 0.0032
Cubeful equities:
1. No double            +0.6292
2. Double, pass         +1.0000  ( +0.3708)
3. Double, take         +0.4355  ( -0.1937)
Proper cube action: No double, take (34.3%)

METの扱いが鍵です。ただ、通常のそれにくらべて難易度が高いです。

I have a theory, although I have not yet dared to share it with anyone, that cube action in a match may be dependent on the match score.

In other words, when one side trails by a significant margin, it may be correct for him to take a position that is a huge pass for money. This is especially true if there are a lot of gammons involved.

At this score, 10-away/5-away, the trailer can take a ridiculous position like this one, provided that he understands he does not need to be a favorite to redouble to 4. After taking, the trailer cannot be timid or bashful about redoubling to 4 on the smallest of pretenses.

事実、25%のダンスでredoubleが返ります。
