Re: [Bug-gnubg] Problems with doubling

[Michael Petch]

When you play a 1 point *match* - a regular win, gammon or backgammon will give you the 1 point you need (The extra don't matter).  So you have a 93% chance to win in the position you posted. GnuBG has 7%. If you could cube (lets say you could), bot would say "My chances are 7%, if I drop your cube I go to 0% and lose the match. If I take, the computer still has a 7% chance".

The cube is only used in matches greater than 1 point or in a money session. This is the reason the bot won't let you cube, and won't ever turn the cube. Your options are to play a money session, or to play matches greater than 1 point.

Yes I am playing 1 point games, and if you say it is that the cube is irrelevant then this would tally with what I have written. But I am not so comfortable with the cube being irrelevant, after all it is in play and it is accepted. I am playing one game and I might equally score 2 from a gammon or via the cube; its still 2 points to me so if gnubg doesn't want to lose by 2 then it should not accept the cube, I reckon.

Unless I am mistaken you are playing a 1 point match. Doubling cube is irrelevant in a pt game. Its possible I put the position in incorrectly, but I think its right.
