Notes about difficulty comparison between current GNUChess "Easy" and "phalanx
-e100 -l- -b-" or "stupid mode".
If you can win GNUChess easy 1 time from 20, then you win phalanx "stupid mode"
always (gnuchess is especially smart for openings).
If you sometimes trick to lose phalanx "stupid mode",
Sorry, right parameters for phalanx are -e 100, not -e 1, or "phalanx -e100 -l-
-b-" to be more precise.
Then it makes few stupid errors, which helps a lot. See more for workaround at:

Workaround to this is using xboard (http://www.tim-mann.org/xboard.html) with
phalanx (http://sourceforge.net/projects/phalanx/) engine.
sudo apt-get install xboard phalanx
mkdir ~/.games
then run
xboard -fcp "phalanx -e 1" -fd ~/.games
where "phalanx -e 1" means passed engine with easiest level
