RE: [Bug-gnubg] Moving Pieces and Dice Throws

[Ian Shaw]

Paul is right that the piece selection is a little off.

I've found that clicking on the left-hand edge of the chequer does not
work, whereas clicking on the right side does.

The dead spot is always the  left edge, whether you are the top or
bottom player, or playing anti-clockwise or clockwise, or playing
full-screen or in a window.

Paul, look at Settings, Options, Dice, and check that Dice Manipulation
is not enabled. I've always used Mersenne Twister without problems but
you can choose from a number of dice generators.  Failing that, I
respectfully suggest that your observations exhibit the well-known bias
to remember the bad sequences, or that your sample size is likely too
small to carry much statistical weight. It may not convince you, but
I'll state it anyway: many world class players use gnubg and trust that
it's dice are fair.

Regards,
Ian

        Hi Paul,
        
        Here's a couple of suggestions to try:
        
        For piece selection, try making the window bigger, removing the
panels on the
        right or trying the full screen mode.
        
        To convince yourself gnubg isn't cheating select the manual dice
option and roll
        the dice rolls yourself (for both sides).
