They also all lose games on endgame same manner. Having won a game by 30 pts
they start giving away those points for - sometimes - imaginary safety,
allowing other player to come within striking distance. Some sort dynamic
komi would be nice  in endgame, but would probably not work.

In Handicaps I think pachi has dynamic komi.
