Right, if you use a chessprogram this way, there are imo reasons to
question your own drives and motives for doing so. As I see it, it has
anyway very little to do with developing your own chess. Playing these
programs are interesting for me but repeating winning setups are not
what I call creativity. For example I had 2 nice wins vs CM8, as black
in a closed KI with following king's attack. Now, this work is done and
personally I will avoid these lines vs CM in the future. Remember with
much more satisfaction a Kn vs B ending - a pawn up - which was possible
to transform into a win vs CM. Constantly closing positions and slowly
building king's attacks is a well known anti computer strategy. But since
these things are known, and hopefully worked upon by the authors, I personally
find it boring to repeat them once more.
One final thing about CM8: Due to following reasons I find it easier to
play than various other top programs:
1) Very limited and small opening book.
2) Dubious time management (known and will be fixed)
3) Just 1 Mb hash tables as default and no way to easily
adjust it without creating a new personality. Really
quite unbelieavable, cause it was possible in CM6.
4) No tablebases for the endgame.
Still, if you get your pieces out in a wrong way you can get busted
heavily as a cruel reminder of your own stupidity...;)
