4. November 2009, 01:25:58 Subject: Re: Bias alanback: I just checked a small, random sample of games: the 13 games (or matches) of regular Backgammon played by alanback in 2009. Out of these 13, 6 games start with identical rolls by black and white. I know, it's hardly conclusive. But still interesting. 4. November 2009, 02:04:34 Subject: Re: Bias  pedestrian: I just did the same exercise on currently open games and 7 out of 15 had identical rolls for the first move 4. November 2009, 02:22:04 Subject: Re: Bias pgt: Just to be clear... is the suspected behaviour that the first move for each player is the same? So if I roll a 3-1 so does my opponent? If so I checked my last 7 games and didn't find it at all... Expected would be 1 in 9? 4. November 2009, 02:25:50 Subject: Re: Bias grenv: No, expected would be 1 in 18. The first player doesn't roll a double, which means that out of all the 36 possible rolls of the second player, only 2 match the roll of the first player. 4. November 2009, 02:37:23 Subject: Re: Bias AbigailII: Ok, but if you take out the doubles, there are only 30 possible rolls I guess... right? so 1 in 15 then? that makes sense... first die 2 in 6, second 1 in 5... 3x5 = 15 4.
