Mr. Joost Aan de Brugh has gently implemented this new ZRF which enforces
the Checkmate condition, and in fact, all winning threatenings are defined
as Check. All cases are considered in a logical manner. The old ZRF
generates some artificial moves with the object of calibrate the pieces
values, in the new ZRF this is not performed, and pieces are valued
incorrectly, by example, Withdrawer values is up to five times the
Coordinator value, and three times the Chameleon value. In the same way,
other assigned values by Zillions are not correct. Some corrections are
still needed to obtain a ZRF that can play this game a little better,
although Zillions is not a very strong player anyway, I can say the old
ZRF played Maxima at a level around 1800, if there is possible a
translation of FIDE-ELO here. The new ZRF 'ELO' is, subjectively, around
1600.
