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.
