I wonder if there is a significant difference between 19.8 SE and 19.8 DC
I see the following problem with having 2 crafty19.8 that are almost the same
and it is learning.

Supose Chinito3.25 beats 19.8 SE with white and later learn and repeat the win
against 19.8 DC when DC does not know about the game.
Chinito3.25 loses against 19.8 SE with black so it does not try to repeat the
opening against 19.8 DC and win.

You can see that 19.8 DC suffers from learning of the opponents.
19.8 SE may suffer from learning of another opponent that has opposite order of
opponents.
