Asunto: Deciphering the database stats...

Lets take the queen vs. archbishop ending:

kqka 31 66.7 32.4 9.2 24 30.5 59.3 16.5 29

white has the queen
black has the archbishop

Max_W = maximum number of moves to win.
This is 31 moves for white.

% win = what percent of all of the white to move positions win? In this case, 66.7%

% draw = 32.4%

Ave_W = the average length of the wins for white to move. With 9.2, most are easy wins. With white having more power and the turn to move, this can be a little misleading.

The other states are for black to move. The longest win is 24 moves for the Archbishop side. This does not mean the Arch is stronger since it wins more quickly. It just means if you don't win within 24 moves, you aren't going to win.

Only 30.5% of the positions win with the Arch to move, and 59.3% are draws. The average win legnth is 16.5 moves when the Arch can move and win.

The last stat, Mzugs, is the count of mutual zugzwang positions.
