Subject: CM6 and the relevance of LCTII

Hello,

As I am a new user of Chess Master 6000 ( I never had a former version of CM
before ) I would like to know, according to your experience with this software,
if CM has a particular reputation of being weak in the positional play, in
opposition with its tactical play and its force in the finals.
Let me explain : I just tested 3 programs with the chess test LCTII ( of
Louguet, a french author ). Here are the results I obtained on my 166 Mz Pentium
with 32 Mo Ram (hashtables homogeneized) :

                      Virtual Chess 1.02    Hiarcs 6.0   CM6000

Positional play :     200/420 pts= 47.6%    210/420=50%    145/420=34.5%

Tactical play :       195/360 = 54%         235/360=65.3%  280/360=77.8%

Finals :              60/270=22%            95/270=35.2%   120/270=44.4%

TOTAL                 2355 ELO(according to LCTII) 2440 ELO  2445 ELO (!)


Well my questions are these :

How do you explain the relative weakness of CM600O performance in positional
play in comparison with the 2 other programs ?

What is the relevance of LCTII test to evaluate the strength of programs, when
we know the true ELO rating of CM6000 is at least 100 points higher ?

What are the tests  the more relevant to evaluate the true ELO-rating of a chess
program ? ( I mean whose results get close to the ELO estimated through many and
many games played as usual ) ?

Every remark, opinion, explanation welcome.
