3 kings vs 1 king is a draw. That's the reason of the high percentage of draws
at top level. Ideas of adating the rules start being tested at international
level because of this problem.

Through time, I have indeed lowered the impact of 5-6 men EGTB on the result. At
first, I thought that it was a must. Now I have a more mixed feeling about this.
With some good knowledge, many positions could be played quite good. Of course
this is different for the 3-4 men database which are much more important.

I only saw the end of the game Damage-Napoleon (endgame winning for Damage, but
drawn on time), what happened in this game ? I feel Damage is a very strong
program. Though I have not seen its games yet.

By the way, I'd be interested in knowing how big Napoleon's evaluation function
is. Can you tell me this ?
