Interesting.

In a similar spirit, I recently tried to measure whether the proportion of draws
increases as strength increases. This is true for human players, but not at all
for computers. I ran this study on the big database containing all of Leo
Dijksman's WBEC games, so the range of playing strength was very wide.

I did this because someone pointed at the increase in the proportion of draws
with strength as supporting the hypothesis that the theoretical value of the
starting position is a draw. Comparing with computers indicate that this
increase mainly support the hypothesis that grandmasters are lazy.
