Only full pairs of games are counted (player A white against player B black and player B white against player A black)
The table data cells contain
game balance ( number of games / number of players )
* Number unreliable, too few games.
Games selection 1, "All players".
All games in the games archive.
Games selection 2, "Strong players".
Subset of games selection 1, including only strong players with max rating above 1500.
Games selection 3, "Very strong players".
Subset of games selection 2, including only very strong players with max rating above 1700.
Games selection 4, "Ultra strong players".
Subset of games selection 3, including only ultra strong players with max rating above 1900.
White = defenders. Black = attackers.
The tafl game balance is calculated as:
(number of most winning color's wins) divided by (number of least winning color's wins),
the number positive if white is more winning, negative if black is more winning.
Draws are counted as half wins.
Examples:
White wins 20 times and black wins 10 times. Balance = +20/10 = +2 (white has twice the chance of winning than black).
White wins 20 times and black wins 30 times. Balance = -30/20 = -1.5 (black has 1.5 times the chance of winning than white).
White wins 10 times and black wins 10 times, and 20 draws. Balance = 20/20 = 1 (perfect balance).
Average is calculated this way:
average of a/b, c/d, e/f and g/h is (a+c+e+g)/(b+d+f+h)
