[Bug-gnubg] Verification of hypergammon database

[Nikolay Marinov]

Hi All,

   I have problem with hyper gammon database for 3 chequer backgammon. 
I generate it myself and also download a generated copy from the 
internet, but when I try to verify this databases with position

         GNU Backgammon  Position ID: ADAAAQAkIAAAAA
                        Match ID   : cAkAAAAAAAAA 

given in gnubg site I've got the following result:

Position ID:    ADAAAQAkIAAAAA
Match ID:       cAkAAAAAAAAA

Evaluator:      HYPERGAMMON-3

            Player       Opponent
Position         3018          2831

Owned cube                    : -0,0230
Centered cube                 : -0,2310
Centered cube (Jacoby rule)   : -0,2186
Opponent owns cube            : -0,3548

       Win     W(g)    W(bg)   L(g)    L(bg)   Equity    Cubeful  
static: 0,818   0,494   0,087   0,000   0,000    +1,218    +0,798   



Cube analysis
0-ply cubeless equity  +1,218
 0,818 0,494 0,087 - 0,182 0,000 0,000
Cubeful equities:
1. Double, pass         +1,000
2. Double, take         +2,381  ( +1,381)
3. No double            +0,798  ( -0,202)
Proper cube action: Double, pass

which is slightly different from evaluation of the same position given in the 
site. I try this in 0.14 and 0.15 version of gnubg on Windows XP SP2, but both 
returns the same result.

Do You have any idea from where this problem may come? Thaks in advance.

Nikolay.
